How to replace Text in UITextInput?

Question

I use UITextInput in customView:

@property (strong,nonatomic) id<UITextInput> textInput;

After typing some chars, I want to go back 4 chars and replace text at this position (replace any to T).Current cursor at the end.

How to do that?

I try replaceRange with UITextRange but don't know how to get position and size with it!

Please help! Thanks in advance!

I just find insertText method. And "Text" has already inserted. I want back 4 chars and replace at this position. — LE SANG, Mar 18 '13 at 02:55
Note: Your `textInput` property should be weak. Strong delegates will likely result in retain cycles. — memmons, Dec 01 '13 at 20:17
