Question

Loading a custom input view into a UITextField, I can arbitrarily change the keyboard type of the standard keyboard between UIKeyboardTypeAlphabet and UIKeyboardTypeNumberPad. Just call something like:

[editingField setKeyboardType:UIKeyboardTypeNumberPad];
[editingField reloadInputViews];

And viola! There is your number pad.

Without changing this block of code, but just making editingField a UITextView instead of a UITextField, it no longer works. According to the docs, these are both compliant with the UITextInput and UITextInputTraits protocols.

It is worth mentioning that the above code actually does work, but only after the user leaves the textView in question and later reselects it. It is almost like reloadInputViews does nothing, and then the textView loads its input views when it becomeFirstResponder.

I have tried all sorts of performSelector: etc and cannot force the issue. Any ideas? How do you make UITextView obey reloadInputViews and dynamically change its inputView?

Answer 1

Are you setting inputView of UITextView to nil before calling?

[editingField setKeyboardType:UIKeyboardTypeNumberPad];
[editingField reloadInputViews];
