Prevent default keyboard from showing when UITextField is pressed

问题

Is there a way to make a custom keyboard to pop up when a user presses on a UITextField. I have a view with a custom keypad on it and I want that to come up when the user presses on the UITextField instead of the default apple keyboard.

回答1:

Since iOS 3.2 there's a property for exactly that, called inputView.

just go like this: [myTextField setInputView:myInputView] - where myInputView is obviously your custom input view. Then the system will pop up your view instead of the predefined keyboards.

回答2:

You may set delegate in your UITextField and return NO in textFieldShouldBeginEditing:.

回答3:

not sure I understand the question? the keyboard type can be assigned to the UITextField so If you want a different one then specify it when initializing the object

UITextField * textFld = [[UITextField alloc] init];
textFld.keyboardType = UIKeyboardTypeNumbersAndPunctuation;
