UPDATE: iOS 4.1 Now has this behaviour built into the SDK. You can set your keyboard type to be UIKeyboardTypeDecimalPad ! Finally !
Of the various keyboards you can choose when developing iPhone apps, the number pad doesn’t come with a decimal point. There is a blank button in the bottom left corner that doesn’t do anything, so I’m going to show you how to put a decimal point button there to look like this:
There are a few other tutorial around that show you how to do this, but i believe mine is better….because the code is simpler to use, its more flexible, and the UI colors and button states are perfectly matched to the rest of the keyboard (unlike some of the other tutorials) The code you use to implement this will look like this:
@interface DecimalPointNumberPadViewController : UIViewController <UITextFieldDelegate> {
NumberKeypadDecimalPoint *numberKeyPad;
}
@end
@implementation DecimalPointNumberPadViewController
- (void) textFieldDidBeginEditing:(UITextField *)textField {
numberKeyPad = [[NumberKeypadDecimalPoint keypadForTextField:textField] retain];
}
- (void)textFieldDidEndEditing:(UITextField *)textField {
[numberKeyPad release];
}
@end
- it works on any number of UITextFields that are displayed on your view controller.
- It will only add one decimal point per text field.
To achieve this, here are the basic steps of what i do:
- Create a custom UIButton with clear background and dark grey text.
- For the highlighted state i change the background image of the button and the text color to be white
- I find the UIKeyboard in the application window and add the custom button at the required location
- I add a delegate to the button to listen for click events and pass the event to a handler which adds a decimal point to the current UITextField
Update 5th June 2010: OS4 compatible and using only public API
As using private API’s is against the SDK agreement, I’ve updated the code to remove references to any private API. It is also now compatible with OS 4.0.
Update 20th July 2010: This code was part of the app I’m working on and was accepted by apple.
A copy of my XCode project is here:

2. Cinto Says:
April 27th, 2010 at 10:14 pmI’m having some difficulty using your custom key pad. When I change from a textfield which uses your custom keypad, to one which uses the default keypad, the decimal image still shows up in the lower left corner when I click there even though the numberkeypad has been releases in the textFieldDidEndEditing method.
Any suggestions?

3. admin Says:
May 1st, 2010 at 2:13 pmHi Cinto,
Yes – its seems this was a bug. I’ve updated the XCode project so that it now removes the decimal button from the keyboard when it is released. I’ve tested and it appears to be working ok now.
Thanks

May 9th, 2010 at 7:34 pmDo you know whether this works with:
1) iPad – When using compatibility mode (ie running it using the iPhone UI)?
2) iPhone OS4?I believe some of the other methods were broken when used with the iPad and then worked with some published modifications. However, I believe iPhone OS4 may have broken it again. Thanks.

5. Sarah Says:
May 19th, 2010 at 8:44 amVery nice, thank you. Unfortunately though I’ve experienced the same as StatCoder; this keypad crashes under OS 4.

May 19th, 2010 at 11:20 amHi StatCode/Sarah,
Thanks for pointing this out. I haven’t tested for iPad or iPhone OS4.
My project is about to be tested on OS4 – so I will be fixing this for the OS4 official release.
Thanks
-
7. StatCoder Says:
May 23rd, 2010 at 6:25 amAny luck with OS4? The issue is the ability to obtain the keyboard view in order to add the button:
for(int i = 0; i < [keyboardWindow.subviews count]; i++) {
keyboard = [keyboardWindow.subviews objectAtIndex:i];
// keyboard view found; add the custom button to it
if([[keyboard description] hasPrefix:@"<UIKeyboard"] == YES)
[keyboard addSubview:button];
}I even tried to add the button view to the main window but it still appears behind the keyboard.

May 26th, 2010 at 1:24 pmHey,
I’m VERY new to iPhone dev and have been looking for a solution to this problem for the last couple of days until I found your page. Could you maybe give me a little bit of help with respect to how I actually implement this in my own app? Do I have to link certain things etc?
-
9. admin Says:
May 26th, 2010 at 2:18 pmConor, just download the example code i provide and copy the source into your project. You don’t have to link any libraries.
-
10. admin Says:
May 26th, 2010 at 2:20 pmStatCoder,
I still haven’t looked into it – however i won’t forget as it’s a requirement of the client in my current project, so it will be done – and i will post the solution here.
Thanks

11. Martinq Says:
May 26th, 2010 at 4:23 pmThis really looks great! But me as others can’t get it to work in 4.0, please post here if anyone find a solution. Thanks!
-
12. StatCoder Says:
May 29th, 2010 at 12:56 amI’m starting to believe that there is no way to access the keyboard anymore. You can add a view to the top edge of a keyboard with inputAccessoryView and you can specify your own custom keyboard view with inputView, however, iterating through the windows, the commonly used method to access the keyboard, was broken in the last two betas. I imagine that some developers are creating their own custom keyboards, however, that seems to be a lot of trouble to add a single custom key.

13. CParib Says:
May 30th, 2010 at 10:03 pmHello,
I have the same problem of Conor Higgins: I am unable to use your code in my project. These are my steps:
1) I added files “DecimalPointButton.h” and “DecimalPointButton.m” to my project.
2) I added the protocol definition to the view controller with the UITextField.
3) I added the “textFieldDidBeginEditing” and “textFieldDidEndEditing” methods to the view controller, like into the article.With these 3 changes nothing happens. What is my error???
Thank you for your help, and thank you for sharing your wonderful code

June 4th, 2010 at 3:38 pmHi All,
I just spent the last hour fixing this in OS4. I have a fix and will post the code on here this weekend.
Thanks
-
15. StatCoder Says:
June 5th, 2010 at 2:56 pmSomeone posted an email that they received from Apple last night regarding the customization of keyboards:
“The organization and layout of the view hierarchy for the keyboard are undocumented and private. There are no public APIs in the iPhone OS SDK provided for keyboard customizations on the iPhone, and modifying or extending the view hierarchy of the keyboard is modifying or extending a private API.”
-
16. admin Says:
June 5th, 2010 at 9:30 pmHi,
I’ve posted the updated code. I’ve also removed any reference to private API’s.
I now add the button to the topmost window on the phone, whatever it may be. So no reference to any private API’s there. I animate it in so that it doesn’t look too out of place.
To work on OS 4.0 i also had to add a timer to the textFieldDidBeginEditing method – this is to allow the keyboard time to become the topmost window, after which the custom button can sit on top again.
Thanks
Dave -
17. StatCoder Says:
June 6th, 2010 at 4:28 amLooks great, Dave. I guess the timer was the key. It was a cinch to implement and seems to be testing out fine so far. Good work. It’s really appreciated.
-
18. admin Says:
June 6th, 2010 at 7:02 pmCParib,
Have you looked into the source project i provided? Its a small project, and if you look at the view controller in there – it shows you what you need to add to the “textFieldDidBeginEditing” and “textFieldDidEndEditing” methods.
Thanks
Dave -
19. Aaron Wardle Says:
June 7th, 2010 at 5:54 amThanks for the info and example here, I got an email from apple on Friday telling me I could not use private API’s to add a decimal point to the keyboard, and I was starting to think I would have to make my very own keyboard.
This example works perfectly for me.
Thanks Aaron

Let us know what happens after your next app submission.
Thanks
-
21. StatCoder Says:
June 10th, 2010 at 6:36 amI have noticed a couple of issues when using this method with multiple textviews. Sometimes the decimal button reanimates itself onto the keypad when switching directly from one textview to another. If you push an alert view such as after doing a range check, the decimal button will not be there after the alert is dismissed. I’m guessing that the button gets animated onto the alert and then disappears with the alert. Thanks.
-
22. admin Says:
June 10th, 2010 at 9:59 amHey,
Yeah, somebody raised this issue to me this morning. I’ll be working on this later, so i’ll probably post an update later on today.
Thanks
-
23. admin Says:
June 10th, 2010 at 6:42 pmI’ve updated the code to remove the bug with the decimal point re-animating itself.
I’ve also tried pushing a UIAlertView on the screen too, and it still seems to work – but i’m not entirely sure what exactly you meant with your bug. Are you doing a range check on the text field with: shouldChangeCharactersInRange ?
My changes are all in the view controller. I now only release the decimal point if the keyboard is dismissed (instead of on each textfield change).
-
24. Steve Says:
June 13th, 2010 at 4:02 pmI’m trying to modify this sample to implement a Done button rather than a decimal point.
To do this I need to implement the keypadWithDelegate rather than the keypadForTextField, so I can use the decimalPointPressed method to do the same job as backgroundTap in your sample.
I tried modifying keypadWithDelegate to return a pointer like keypadForTextField does, but I’m missing something. When I release the numkeypad the Done button stays on screen.
Can you show me a small sample? Thanks!
-
25. Steve Says:
June 13th, 2010 at 5:20 pmI figured it out. I modified keypadWithTextField to do double duty:
+ (NumberKeypadDecimalPoint *) keypadForTextField:(UITextField *)textField id:_delegate {
NumberKeypadDecimalPoint *keypad = [[NumberKeypadDecimalPoint alloc] init];
keypad.decimalPointButton = [DecimalPointButton decimalPointButton];
keypad.currentTextField = textField; //Save reference to current textfield being edited
[keypad.decimalPointButton addTarget:_delegate action:@selector(decimalPointPressed) forControlEvents:UIControlEventTouchUpInside];
[keypad addButtonToKeyboard:keypad.decimalPointButton];
return [keypad autorelease];
}Then, in the delegate decimalPointPressed, I duplicated the backgroundTap code. I changed the button code to add DoneUp and DoneDown images instead of the decimal point, and voila!

27. Aaron Wardle Says:
June 15th, 2010 at 7:18 pmHi,
I have just tried your latest code and think I have found a glitch, if you randomly click each text box / background a lot of times eventually the . will not appear or over lays on the standard keyboard.
I am testing this with OS4.
Thanks Aaron

31. Brent Says:
June 24th, 2010 at 12:59 pmFirst off, thanks for the great post. Secondly, I’ve noticed that when you go from a UITable view to a new view and call out the keyboard, the decimal point doesnt appear until you click another text field and reload the delegate. Then when you leave the view and go back to the table view the decimal point stays active until the view switch animation i finished. Any recommendations?

32. Ploeter Says:
June 26th, 2010 at 10:32 amHi thank you for all your work and for publishing it…
I think I have found a little error… when I run your sample project and I go in one of the two textfields with a number-keypad but I don’t press anything and then I go into the normal-keypad textfield… I can’t press the “.?123″ key as the decimal point keeps showing up… So I get a decimal point in the normal-keypad textfield, when I don’t want it…
Could take a look at this and see if you have the same issue?
Thanks. -
33. admin Says:
June 27th, 2010 at 7:28 pm@Aaron Wardle
I’ve fixed this issue you reported. Thanks.
@Ploeter
I’ve also fixed this issue.
Both are in the new project I’ve uploaded (version 4).
I’ve only tested on the simulator on OS 3.1.3 and OS 4.

34. Brent Says:
June 28th, 2010 at 3:19 pm@admin
Still getting the decimal point overlay. Would you use any special methods to release the keypad at view transition?
-
35. admin Says:
June 28th, 2010 at 4:02 pmHi Brent,
If you saved a reference to your numberKeyPad in textFieldDidBeginEditing you should be able to remove it from the screen using:
[self.numberKeyPad removeButtonFromKeyboard];
self.numberKeyPad = nil;Try that and let me know how you get on.
Thanks
-
36. Brent Says:
June 28th, 2010 at 7:02 pmOk, it responds from view transition with a:
[numberKeyPad removeButtonFromKeyboard];
numberKeyPad = nil;errors out when you call self.* but it works.
-
37. admin Says:
June 28th, 2010 at 7:32 pmWell you can only call self.* if you have it declared as a property on your view controller.
-
38. Robin Pain Says:
July 1st, 2010 at 3:19 pmIt this a good way to make the decimal point key stay “in place” after orientation?…
In NumberKeypayDecimalPoint.m’s init() add this line:
…
[[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(orientationDidChange:) name:UIDeviceOrientationDidChangeNotification object:nil];
…and this method:
- (void)orientationDidChange:(NSNotification *)notificaton {
if([[UIDevice currentDevice] orientation] == UIDeviceOrientationPortrait)
self.frame = CGRectMake(0, 427, 105, 53);
else
self.frame = CGRectMake(0, 281, 158, 39);
}or is there a “proper” way to do it?
Thanks very much for this excellent article. I am a newbie and would not have had any idea where to start.
-
39. Robin Pain Says:
July 1st, 2010 at 3:50 pm…but when the keyboard window is rotated to Horizontal and then its “parent” is returned to, and then the parent is de-rotated to Vertical and the keyboard re-entered – the button is still in Horizontal position (on top of the ’1′ key)…
…so I altered the above code to this:
- (void)orientationDidChange:(NSNotification *)notificaton {
[self initButton];
}-(void)initButton{
if([[UIDevice currentDevice] orientation] == UIDeviceOrientationPortrait)
self.frame = CGRectMake(0, 427, 105, 53);
else
self.frame = CGRectMake(0, 281, 158, 39);
}and added this line:
keypad.decimalPointButton.initButton;to the keypadForTextField(…) method, just after the if(…) i.e.
if( !(keypad) ) {
…
}
keypad.decimalPointButton.initButton;
keypad.currentTextField = textField;

July 6th, 2010 at 9:40 pmI’m trying to incorporate this into a tab view. I add the tab view manually (starting with view controller then adding the tab view to the main.xib). I got your code to work with my single view controller before adding the tab bar view. When I add the other view and the tab bar, it won’t function. I tried using your original code, added a second view (with exactly the code and nib of the first one with “view 2″ put in so I could tell the difference) and put in the tab bar into main.xib. I think I connected everything correctly but it won’t work. On yours (with the added 2nd view and tab bar) the app works but without the tab bar. On mine, it doesn’t do anything (literally, it shows a black screen – builds just fine, no errors and no exceptions, but black screen on the simulator).
Any ideas? Have you used it in a tab bar controller app before?

41. admin Says:
July 6th, 2010 at 10:17 pmSounds like you have other unrelated issues. You might be better posting this question on some forums such as the apple dev forums. Sounds like you haven’t reconnected your view to your controller at a guess. And yes, I use this code within a tab bar controller.

The code that you displayed on this page (for “how to implement” the look) is confusing me. What file am I supposed to put it in?
Sorry, I’m completely new to all of this.

July 17th, 2010 at 12:29 pmI’ll tell you that the old code with the method (void) keyboardWillShow:(NSNotification *)note is working with OS4. But you need a bit update.
You don’t need to detect the keyboard prefix because in a TextEdit, because natively, you have a keyboard with it.
I’ll post my code when i am in my mac. -
47. Vivelee Says:
July 21st, 2010 at 10:34 amStrange thing. Your new code works very good… until i save it.
When i debug your code- there is a dot and turning off keyboard.
When i just save project (eg in IB but without doing any changes- just saving) dot and turning off keyboard is lost :/ After debugging there is nothing more than just normal number pad (without dot) and it doesn’t turn off.Why is it working like this?

I’ve been working with this code and it seems to be working as in I’m not getting any errors but the decimal button just isn’t showing up. What am I missing? Has anyone else experienced something like this? I thought it might have something to do with the fact that I have 2 view controllers, but it still shouldnt really be causing that.
If anyone can help it would be great. I’m pretty confused at this stage.

-
54. Ivan Says:
July 30th, 2010 at 6:59 pmI’m sure you are aware that you can receive notifications for when the keyboard appears. Why not use the UIKeyboardDidShowNotification instead of the timer to trigger the adding of the button? I guess it might be harder to animate it in in that case. The fact that the implementation uses a timer makes me uncomfortable though, but otherwise, great work.
-
55. Ralf Says:
August 2nd, 2010 at 7:44 pmHi Bob1601,

in the myproject.h i added:
- #import “NumberKeypadDecimalPoint.h” at the beginning of the file (after the UIKit)
- NumberKeypadDecimalPoint *numberKeyPad; in the interface
- the property before the @endin the .m file i added:
-@synthesize of my labels, my fields and “numberKeyPad”
- i did “copy and past” of textFieldShouldBeginEditing, textFieldDidBeginEditing and textFieldDidEndEditing.when i tap on my text fileds, appear the normal number pad.
i’m sure that the label are connected with the class: i can use their contents to calculate and display the result.

October 31st, 2010 at 7:08 pmWhat happens if the device is using an OS less than 4.1? Will it just show a numeric keypad without the decimal? Also, this still isn’t the ideal numeric keypad. It still is arrange in the telephone keypad order with “1″ in the top left rather than the traditional calculator or keyboard numeric keypad with the “1″ in the lower left. It also has the letters from the telephone keypad.

[super setNeedsDisplayInRect:rect];….
}cheers

March 12th, 2011 at 9:45 pmFirst off, thanks for posting this great code. One problem is when the keyboard pops up, the view no longer shifts up (via the keyboardWillShow notifications). Is there something that needs to be changed to react to this ‘new’ number pad?
Thanks again.

July 14th, 2011 at 6:44 pmcool idea, but …
#1 what about the landscape mode ? the dot is not visible.#2 for me, the dot also shows up in other types of input fields that are in the same view (ie Numbers and Punctuations).

September 19th, 2011 at 7:33 pmFrom OS 4.1 & above, the Decimal Keyboard is now available in the SDK.
Try this:
yourTextField.keyboardType = UIKeyboardTypeDecimalPad;

November 24th, 2011 at 5:29 amI have used the code to show a DONE button on the numeric keypad. It works perfectly fine till iOS 4.3. However, I am facing a strange problem using this code in iOS 5.0. For any textfield having a numeric keypad, if there are any validations done and if we get an Alertview. Then once the focus goes back to the same text field the Keypad comes up without the DONE button (i.e. DONE button disappears) and strangely this happens in iOS 5.0 only. Could you please provide some inputs on this ? It would be of great help.

January 7th, 2012 at 4:54 pmJust figured out, that there is a bug since iOS4.3. if Emoji Keyboard is enabled. If you use Emoji keyboard in i.e. messages and leave it (don`t change it back to normal), the Emoji Keyboard appears as well in the App where the NumberKeyPad usually should appear. Has somebody maybe already a fix for that? Thank´s in advance, Best regards, Jens
