How to replace Text in UITextInput?

Question

I use UITextInput in customView:

MyCode: https://github.com/lequysang/github_zip/blob/master/UITextInputDebug.zip

@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!
