在您的應用程序中模仿iPhone的撥號盤

Question

我正在製作一個應用程序，需要撥號盤才能從應用程序撥打電話號碼。 iphone撥號盤非常棒，但無法在我的應用程序中模仿它。 我認爲這樣做的唯一方法是爲每個號碼分別設置按鍵，但與原來的撥號鍵盤看起來非常不同。

如果您有UITextField，則可以將其設置爲keyboardType屬性，以在用戶關注它時顯示數字鍵盤。

UITextField *textField; 
textfield.keyboardType = UIKeyboardTypePhonePad; 

keyboardType可以從這個enum什麼：

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). 

    UIKeyboardTypeAlphabet = UIKeyboardTypeASCIICapable, // Deprecated 

} UIKeyboardType;
