のkeyboardType
プロパティがあります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.

UITextInputTraits
プロトコルの特性ですUITextField
。
現在フォーカスされているフィールドでキーボードタイプをすぐに更新したい場合は、もう1つの手順があります。
// textField is set to a UIKeyboardType other than UIKeyboardTypeEmailAddress
[textField setKeyboardType:UIKeyboardTypeEmailAddress];
[textField reloadInputViews];
への呼び出しreloadInputViews
がないと、選択したフィールド(最初のレスポンダー)がフォーカスを失い、再びフォーカスするまで、キーボードは変化しません。
UIKeyboardType
値の完全なリストはここにあります、または:
typedef enum : NSInteger {
UIKeyboardTypeDefault,
UIKeyboardTypeASCIICapable,
UIKeyboardTypeNumbersAndPunctuation,
UIKeyboardTypeURL,
UIKeyboardTypeNumberPad,
UIKeyboardTypePhonePad,
UIKeyboardTypeNamePhonePad,
UIKeyboardTypeEmailAddress,
UIKeyboardTypeDecimalPad,
UIKeyboardTypeTwitter,
UIKeyboardTypeWebSearch,
UIKeyboardTypeAlphabet = UIKeyboardTypeASCIICapable
} UIKeyboardType;
[textField reloadInputViews];
私が行方不明だったということでした。ありがとう!
reloadInputViews
は、別注のUITextInput
実装でも機能します。
_textField .keyboardType = UIKeyboardTypeAlphabet;
_textField .keyboardType = UIKeyboardTypeASCIICapable;
_textField .keyboardType = UIKeyboardTypeDecimalPad;
_textField .keyboardType = UIKeyboardTypeDefault;
_textField .keyboardType = UIKeyboardTypeEmailAddress;
_textField .keyboardType = UIKeyboardTypeNamePhonePad;
_textField .keyboardType = UIKeyboardTypeNumberPad;
_textField .keyboardType = UIKeyboardTypeNumbersAndPunctuation;
_textField .keyboardType = UIKeyboardTypePhonePad;
_textField .keyboardType = UIKeyboardTypeTwitter;
_textField .keyboardType = UIKeyboardTypeURL;
_textField .keyboardType = UIKeyboardTypeWebSearch;
スウィフト4
条件が満たされたときにキーボードの種類を変更しようとしている場合は、これに従ってください。例えば:私たちはからキーボードの種類を変更する場合のデフォルトのに数パッドテキストフィールドの数が4または5であるときは、この操作を行います。
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()
}
これにはと呼ばれるプロパティがありますkeyboardType
。何をしたいと思うことは、あなたが文字列を持っているところ置き換えである @"Number Pad
と@"Default
してUIKeyboardTypeNumberPad
とUIKeyboardTypeDefault
。
新しいコードは次のようになります。
if(user is prompted for numeric input only)
[textField setKeyboardType:UIKeyboardTypeNumberPad];
else if(user is prompted for alphanumeric input)
[textField setKeyboardType:UIKeyboardTypeDefault];
幸運を!
UIDatePicker
入力として使用したい人のために:
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]];
}
