Question

Is it possible to programmatically change the keyboard type of a uitextfield so that something like this would be possible:

if(user is prompted for numeric i         


        

Answer 1

to make the text field accept alpha numeric only set this property

textField.keyboardType = UIKeyboardTypeNamePhonePad;

Answer 2

Swift 4

If you are trying to change your keyboard type when a condition is met, follow this. For example: If we want to change the keyboard type from Default to Number Pad when the count of the textfield is 4 or 5, then do this:

textField.addTarget(self, action: #selector(handleTextChange), for: .editingChanged)

@objc func handleTextChange(_ textChange: UITextField) {
 if textField.text?.count == 4 || textField.text?.count == 5 {
   textField.keyboardType = .numberPad
   textField.reloadInputViews() // need to reload the input view for this to work
 } else {
   textField.keyboardType = .default
   textField.reloadInputViews()
 }

Answer 3

Yes you can, for example:

[textField setKeyboardType:UIKeyboardTypeNumberPad];

Answer 4

This is the UIKeyboardTypes for Swift 3:

public enum UIKeyboardType : Int {

    case `default` // Default type for the current input method.
    case asciiCapable // Displays a keyboard which can enter ASCII characters
    case numbersAndPunctuation // Numbers and assorted punctuation.
    case URL // A type optimized for URL entry (shows . / .com prominently).
    case numberPad // A number pad with locale-appropriate digits (0-9, ۰-۹, ०-९, etc.). Suitable for PIN entry.
    case phonePad // A phone pad (1-9, *, 0, #, with letters under the numbers).
    case namePhonePad // A type optimized for entering a person's name or phone number.
    case emailAddress // A type optimized for multiple email address entry (shows space @ . prominently).

    @available(iOS 4.1, *)
    case decimalPad // A number pad with a decimal point.

    @available(iOS 5.0, *)
    case twitter // A type optimized for twitter text entry (easy access to @ #)

    @available(iOS 7.0, *)
    case webSearch // A default keyboard type with URL-oriented addition (shows space . prominently).

    @available(iOS 10.0, *)
    case asciiCapableNumberPad // A number pad (0-9) that will always be ASCII digits.


    public static var alphabet: UIKeyboardType { get } // Deprecated
}

This is an example to use a keyboard type from the list:

textField.keyboardType = .numberPad

Answer 5

    textFieldView.keyboardType = UIKeyboardType.PhonePad

This is for swift. Also in order for this to function properly it must be set after the textFieldView.delegate = self

Answer 6

It's worth noting that if you want a currently-focused field to update the keyboard type immediately, there's one extra step:

// textField is set to a UIKeyboardType other than UIKeyboardTypeEmailAddress

[textField setKeyboardType:UIKeyboardTypeEmailAddress];
[textField reloadInputViews];

Without the call to reloadInputViews, the keyboard will not change until the selected field (the first responder) loses and regains focus.

A full list of the UIKeyboardType values can be found here, or:

typedef enum : NSInteger {
    UIKeyboardTypeDefault,
    UIKeyboardTypeASCIICapable,
    UIKeyboardTypeNumbersAndPunctuation,
    UIKeyboardTypeURL,
    UIKeyboardTypeNumberPad,
    UIKeyboardTypePhonePad,
    UIKeyboardTypeNamePhonePad,
    UIKeyboardTypeEmailAddress,
    UIKeyboardTypeDecimalPad,
    UIKeyboardTypeTwitter,
    UIKeyboardTypeWebSearch,
    UIKeyboardTypeAlphabet = UIKeyboardTypeASCIICapable
} UIKeyboardType;
