Which UIKeyboardType can I use on the iPad

Question

I have a textField object in an app for iPad. I would like to give the user a convenient keyboard for entering numbers. In my code, I added:

UITextField *textField = [[UITextField alloc] initWithFrame:frame]; textField.keyboardType = UIKeyboardTypeDecimalPad; 

According to the docs, this is a valid keyboard type, but when I edit a text box, a regular ASCII keyboard appears. However, when I change it to:

 textField.keyboardType = UIKeyboardTypePhonePad; 

The keyboard looks like this:

Ideally, I would like the keyboard to have only numbers and a decimal point, but is this impossible on the iPad? Does anyone have a definitive list of which keyboards work on iPhone vs iPad? Apple is unclear. I also saw this question , which is similar, but none of the answers touch my point.

Thanks!

Answer 2

I tested which types of keyboards are available for iPad / iPhone using Simulator after receiving a warning

"Cannot find a keyboard that supports Type 8 for the Wildcat-QWERTY-Pad; using 2592645918_Wildcat-Alphabetical-Keyboard_Capital-letter"

on iPad for UIKeyboardTypeDecimalPad . Hope this is helpful for the next person who stumbles here.

IPad:

• UIKeyboardTypeASCIICapable
• UIKeyboardTypeNumbersAndPunctuation
• UIKeyboardTypeURL
• UIKeyboardTypeNumberPad
• UIKeyboardTypeNamePhonePad
• UIKeyboardTypeEmailAddress
• UIKeyboardTypeTwitter

So everything except UIKeyboardTypeDecimalPad . using the UIKeyboardTypeDecimalPad , you only get helmets on your wrist in iOS 5.1 or 6.1.

iPhone:

• UIKeyboardTypeASCIICapable
• UIKeyboardTypeNumbersAndPunctuation
• UIKeyboardTypeURL
• UIKeyboardTypeNumberPad
• UIKeyboardTypeNamePhonePad
• UIKeyboardTypeEmailAddress
• UIKeyboardTypeDecimalPad
• UIKeyboardTypeTwitter

i.e. all of them
