Or maybe add a comma on the number pad without creating a custom keyboard.
I tried changing NSLocale to to another country but that didn't work. I have a function that separates multiple numbers from textFiled to evaluate them separately separated by commas but the keyboards do not contain a comma and i would rather not use the numbers and punctuation keyboard for this. Any help is appreciated. Using Xcode 7.2.
You can't change the keys on any of the built-in keyboards.
You can create your own keyboard view with the inputs you want (numbers, the comma, backspace) and set it as the inputView of your text field. The system will display your keyboard view instead of a standard keyboard when your text field becomes first responder.
Or you can just create, say, a toolbar with a comma button on it, and set the toolbar as your text field's inputAccessoryView, and let the text field use the standard decimal pad for numbers and backspace. The system will display your input accessory view above the standard keyboard when your text field becomes first responder.
Read “Input Views and Input Accessory Views” in the Text Programming Guide for iOS.

I would like to ensure that names in a multi-line copyright string on the launch screen do not get split by line breaks on different devices. Inside a view controller with a UILabel outlet textLabel, the escape sequence "\u{00a0}" works programmatically:
textLabel.text = "Lots of text before... Firstname\u{00a0}Lastname... and after."
It displays the string with the escape sequence replaced by a space and the words either side always appear on the same line.
However, I can't get it work by putting it in as the value in a UILabel in Interface Builder - either in LaunchScreen or any other View Controller. It just displays the string with the codes left as typed. I've tried all the various combinations of \u, \U, \\u, \\U, \x+, etc. suggested in several SO questions to no avail. I think intervening in the display of the launch screen programmatically is impossible.
Have I missed something?
Don't use \u{00a0} in the text you enter into the storyboard. Enter an actual non-breaking space. The easiest way is to type ⌥-space (option-space).
If you ever need to enter any other special characters, another option is to use the standard Character Viewer. Select Emoji & Symbols from the Edit menu to bring up the Character Viewer. Then find the desired character that you wish to put in a label. You can do this in Swift code as well instead of typing cryptic Unicode escape sequences into your strings.
I Created a keyboard extension like this:
But I don't know where to define my custom keyboard to be a numeric pad.
If any number type textfield tapped by user, the iOS default numeric pad will present with no switch button to my custom numeric pad.
The question is:
How to define my custom keyboard to be a numeric pad?
From Apple's docs Custom Keyboard:
Your custom keyboard is also ineligible to type into so-called phone pad objects, such as the phone number fields in Contacts. These input objects are exclusively for strings built from a small set of alphanumeric characters specified by telecommunications carriers and are identified by having one or another of the following two keyboard type traits:
UIKeyboardTypePhonePad
UIKeyboardTypeNamePhonePad
When a user taps in a phone pad object, the system temporarily replaces your keyboard with the appropriate, standard system keyboard. When the user then taps in a different input object that requests a standard keyboard via its type trait, your keyboard automatically resumes.
So, it looks like you cannot do what you're asking.
I have some alphanumeric content that gets entered routinely and is mostly numbers, so I'm wondering if there's a way to start in the numeric side of the keyboard but still have the option to switch to the alphabetic keyboard in Objective-C for iPhone development specifically. I've found plenty of info on using the numeric keyboard but I'd like to start there but still be able to enter letters if that's possible.
Thanks.
Set the keyboardType property to UIKeyboardTypeNumbersAndPunctuation.
This will default the iPhone's keyboard to show numbers and punctuation but the little "ABC" key will be in the bottom left allowing the user to switch back to the letters (and then back to numbers and punctuation).
Try this:
[Objective - C]
[self.myTextField setKeyboardType: UIKeyboardTypeNumbersAndPunctuation];
[Swift]
self.myTextField.keyboardType = .NumbersAndPunctuation
// You can also set this property from the storyboard.
Is there a native UI control for code input text field, for example like Whatsapp:
No. To achieve this, they're almost certainly tapping into the textField:shouldChangeCharactersInRange:replacementString: method for their UITextField, selectively accepting and formatting user input to match the dash-if-empty approach.
Further, I'm sure they've subclassed the field; per your comments there isn't a blue cursor - which isn't standard for a UITextField.
No there isn't. Use a UITextField, fill it with dashes, keep track of how many characters the user has entered, and replace the dashes accordingly as the user types.
There's a 4-digit code input text field called CodeInputView written in Swift.
In the past I've added a UITextField to the view and set its hidden == true. Then I show/hide the keyboard by calling becomeFirstResponder()/resignFirstResponder() on it. I listen for text did change notifications and update a visible label with the value of the hidden text field.
My aim is to have text boxes - a set amount per level for people to guess a hidden word. I don't want the UITextfield to be tapped and then bring up the keyboard, I'd like to have a different button that brings up the keyboard - if that's possible.
If each box is a separate text field how could I go about entering text. When a user types on the standard apple keypad, how could each character be inputted into a certain text field. I'd preferably like the text to show in the box as soon as a key is tapped.
I'm also having trouble clearing certain letters. Say a user mis-spells something and doesn't realise until the keyboard has resigned as first responder, how could I make it so that a user can tap on maybe two boxes if the rest of the word is spelt right and the program clear it?
Is there any way of writing the program so that it inputs text only if the text field is empty? Continuing with the example above they switch two letters, they tap to clear, they then bring up the keypad and the next key then pressed fills the empty boxes. Not allowing the program to input text in a used text field that only contains a single character?
I'm using Cocos2d - I don't know if that makes a difference. I hope you understand what I mean, although I'm rather bad at explaining.
Thank you in advance for your time and any help :).
Instead of having a textbox that you don't want users to edit, why not use a label?
To show the keyboard, you need to have it linked to some UITextField (or similar). You could use an invisible UITextField, and then monitor the input and send the characters to the correspinding labels. Refer to this question.
To check if a textfield has anything in it:
[textField.text length] > 0, but I would use labels instead of textfields.
I dont really understand the other parts of your question.
