Istnieje keyboardType
właściwość dla UITextField
:
typedef enum {
UIKeyboardTypeDefault, // Default type for the current input method.
UIKeyboardTypeASCIICapable, // Displays a keyboard which can enter ASCII characters, non-ASCII keyboards remain active
UIKeyboardTypeNumbersAndPunctuation, // Numbers and assorted punctuation.
UIKeyboardTypeURL, // A type optimized for URL entry (shows . / .com prominently).
UIKeyboardTypeNumberPad, // A number pad (0-9). Suitable for PIN entry.
UIKeyboardTypePhonePad, // A phone pad (1-9, *, 0, #, with letters under the numbers).
UIKeyboardTypeNamePhonePad, // A type optimized for entering a person's name or phone number.
UIKeyboardTypeEmailAddress, // A type optimized for multiple email address entry (shows space @ . prominently).
UIKeyboardTypeDecimalPad, // A number pad including a decimal point
UIKeyboardTypeTwitter, // Optimized for entering Twitter messages (shows # and @)
UIKeyboardTypeWebSearch, // Optimized for URL and search term entry (shows space and .)
UIKeyboardTypeAlphabet = UIKeyboardTypeASCIICapable, // Deprecated
} UIKeyboardType;
Twój kod powinien brzmieć
if(user is prompted for numeric input only)
[textField setKeyboardType:UIKeyboardTypeNumberPad];
if(user is prompted for alphanumeric input)
[textField setKeyboardType:UIKeyboardTypeDefault];

Warto zauważyć, że jeśli chcesz, aby aktualnie skupione Pole natychmiast zaktualizowało typ klawiatury, jest jeszcze jeden krok:
// textField is set to a UIKeyboardType other than UIKeyboardTypeEmailAddress
[textField setKeyboardType:UIKeyboardTypeEmailAddress];
[textField reloadInputViews];
Bez wywołania reloadInputViews
, klawiatura nie zmieni się, dopóki wybrane pole (first responder) nie straci i odzyska fokus.
Pełna lista wartości UIKeyboardType
znajduje się tutaj , lub:
typedef enum : NSInteger {
UIKeyboardTypeDefault,
UIKeyboardTypeASCIICapable,
UIKeyboardTypeNumbersAndPunctuation,
UIKeyboardTypeURL,
UIKeyboardTypeNumberPad,
UIKeyboardTypePhonePad,
UIKeyboardTypeNamePhonePad,
UIKeyboardTypeEmailAddress,
UIKeyboardTypeDecimalPad,
UIKeyboardTypeTwitter,
UIKeyboardTypeWebSearch,
UIKeyboardTypeAlphabet = UIKeyboardTypeASCIICapable
} UIKeyboardType;

textFieldView.keyboardType = UIKeyboardType.PhonePad
To dla Swifta. Również aby to działało poprawnie musi być ustawione po textFieldView.delegate = self

Aby pole tekstowe przyjęło wartość alfanumeryczną Ustaw tylko tę właściwość
textField.keyboardType = UIKeyboardTypeNamePhonePad;

Istnieje właściwość o nazwie keyboardType
.
To, co będziesz chciał zrobić, to zastąpić ciągi @"Number Pad
i @"Default
przez UIKeyboardTypeNumberPad
i UIKeyboardTypeDefault
.
Twój nowy kod powinien wyglądać mniej więcej tak:
if(user is prompted for numeric input only)
[textField setKeyboardType:UIKeyboardTypeNumberPad];
else if(user is prompted for alphanumeric input)
[textField setKeyboardType:UIKeyboardTypeDefault];

Dla osób, które chcą użyć UIDatePicker
jako wejścia:
UIDatePicker *timePicker = [[UIDatePicker alloc] initWithFrame:CGRectMake(0, 250, 0, 0)];
[timePicker addTarget:self action:@selector(pickerChanged:)
forControlEvents:UIControlEventValueChanged];
[_textField setInputView:timePicker];
// pickerChanged:
- (void)pickerChanged:(id)sender {
NSDateFormatter *formatter = [[NSDateFormatter alloc] init];
[formatter setDateFormat:@"d/M/Y"];
_textField.text = [formatter stringFromDate:[sender date]];
}

Swift 4
Jeśli próbujesz zmienić typ klawiatury, gdy warunek jest spełniony, wykonaj to. Na przykład: jeśli chcemy zmienić typ klawiatury z Default na Number Pad , gdy liczba pola tekstowego wynosi 4 lub 5, wykonaj następujące czynności:
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 work
} else {
textField.keyboardType = .default
textField.reloadInputViews()
}
