Text objects can be targeted for specific types of input, such as plain text, email, numeric entry, and so on. The keyboard style identifies what keys are available on the keyboard and which ones appear by default. The default value for this property is UIKeyboardTypeDefault.
Available types for the keyboards are:
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).
#if __IPHONE_4_1 <= __IPHONE_OS_VERSION_MAX_ALLOWED
UIKeyboardTypeDecimalPad, // A number pad with a decimal point.
#endif
UIKeyboardTypeAlphabet = UIKeyboardTypeASCIICapable, // Deprecated
} UIKeyboardType;
Available types for the return key are:
typedef enum {
UIReturnKeyDefault,
UIReturnKeyGo,
UIReturnKeyGoogle,
UIReturnKeyJoin,
UIReturnKeyNext,
UIReturnKeyRoute,
UIReturnKeySearch,
UIReturnKeySend,
UIReturnKeyYahoo,

UITextAutocapitalizationTypeSentences,
UITextAutocapitalizationTypeAllCharacters,
