Here is what i use to detect paste events in UITextView:

 // Set this class to be the delegate of the UITextView. Now when a user will paste a text in that textview, this delegate will be called.
-(BOOL)textView:(UITextView *)textView shouldChangeTextInRange:(NSRange)range replacementText:(NSString *)text {

    // Here we check if the replacement text is equal to the string we are currently holding in the paste board
    if ([text isEqualToString:[UIPasteboard generalPasteboard].string]) {

        // code to execute in case user is using paste

    } else {

        // code to execute other wise
    }

    return YES;
}
