是否有可能以编程方式更改的UITextField的键盘类型，所以这样的事情是可能的：编程改变的UITextField键盘类型

if(user is prompted for numeric input only) 
    [textField setKeyboardType: @"Number Pad"]; 

if(user is prompted for alphanumeric input) 
    [textField setKeyboardType: @"Default"];

我建议你将'doozy'这个词改为更常用的东西。请记住，SO是国际站点，不是北美站点 – abbood

有一个UITextField一个keyboardType属性：

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;

您的密码应为

if(user is prompted for numeric input only) 
    [textField setKeyboardType:UIKeyboardTypeNumberPad]; 

if(user is prompted for alphanumeric input) 
    [textField setKeyboardType:UIKeyboardTypeDefault];

哇。非常简单。谢谢！ –

请注意，这不会阻止聪明/错误的用户输入其他字符。例如：如果表情符号键盘在*之前处于活动状态*他们点击您的号码字段，他们可以自由地在其中输入笑脸。对此，你无能为力，这绝对是苹果的错误，但你应该**确保你的代码不会崩溃，如果你在数字字段中得到非数字。 –

今天发现，这是'UITextField'采用的'UITextInputTraits'协议的属性。 – rounak

是你可以，例如：

[textField setKeyboardType:UIKeyboardTypeNumberPad];

有一个属性为这keyboardType。你想要做的是取代你的字符串@"Number Pad和@"Default与UIKeyboardTypeNumberPad和UIKeyboardTypeDefault。

你的新代码应该是这个样子：

if(user is prompted for numeric input only) 
    [textField setKeyboardType:UIKeyboardTypeNumberPad]; 

else if(user is prompted for alphanumeric input) 
    [textField setKeyboardType:UIKeyboardTypeDefault];

祝您好运！

，以使文本字段接受字母数字只设置该属性

textField.keyboardType = UIKeyboardTypeNamePhonePad;

值得一提的是，如果你想有一个当前重点场更新键盘立即输入，还有一个额外的步骤：

// textField is set to a UIKeyboardType other than UIKeyboardTypeEmailAddress 

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

没有调用reloadInputViews，键盘不会改变，直到选定字段（first responder）失去和获得焦点。

的UIKeyboardType值can be found here，或的完整列表：

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

这是有用的信息知道，我会建议做一个问答式自答问题，只是为了提取有关当前重点字段输入更改的信息（这就是我找到这个答案时寻找的） – Stonz2

它也是值得一提的是，在当前未关注的文本字段上调用reloadInputViews不会立即改变键盘类型。所以最好先调用[textfield becomeFirstResponder]，然后[textField reloadInputViews] – Qiulang

它是'[textField reloadInputViews];'我错过了。谢谢！ –

谁想要使用UIDatePicker作为输人：

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]]; 
}

_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;

textFieldView.keyboardType = UIKeyboardType.PhonePad

这是迅速的。此外，在为了这个正常工作，必须在

后设置这是UIKeyboardTypes为雨燕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 
}

这是从列表中使用键盘类型的例子：

textField.keyboardType = .numberPad
