How to cancel UITextView using the Finish button

Question

I was wondering if any of you knew how to access this button that appears above the keyboard when editing.

I have seen this before, there is a transparent black area above the keyboard, and there is a blue Finish button on the right.

I could do it manually using my own animations and buttons above the keyboard in my application to resign UITextView, but I would prefer to use the Apple GUI elements that people know.

Does anyone have any info on where this Done button comes from?

You really don't get access to this button, but through the UITextViewDelegate protocol, you can essentially:

http://developer.apple.com/library/ios/#DOCUMENTATION/UIKit/Reference/UITextViewDelegate_Protocol/Reference/UITextViewDelegate.html

Implement

- (void)textViewDidEndEditing:(UITextView *)textView 

and assign the UIViewController containing the text view to the textview delegate.

Inside this procedure, you can do what you want! You will need to call

 resignFirstResponder 

method.

http://developer.apple.com/library/ios/#DOCUMENTATION/UIKit/Reference/UIResponder_Class/Reference/Reference.html#//apple_ref/occ/instm/UIResponder/resignFirstResponder

You will need to implement a keyboard style that implements this blue button.

FINAL ANSWER

 - (void)textViewDidEndEditing:(UITextView *)textView{ [textView resignFirstResponder]; }
