iOS set Keyboard Type

It is simple to set keyboard type for your TextField
First of all, let's get enum

typedef enum {
   UIKeyboardTypeDefault,
   UIKeyboardTypeASCIICapable,
   UIKeyboardTypeNumbersAndPunctuation,
   UIKeyboardTypeURL,
   UIKeyboardTypeNumberPad,
   UIKeyboardTypePhonePad,
   UIKeyboardTypeNamePhonePad,
   UIKeyboardTypeEmailAddress,
   UIKeyboardTypeAlphabet = UIKeyboardTypeASCIICapable
} UIKeyboardType;

// set keyboard type to UITextField, Done.
[textField setKeyboardType:UIKeyboardTypeDecimalPad];
