How to hide Textbox Keyboard when “Done / Return” Button is pressed Xcode 4.2

Question

I created a Text Field in Interface Builder. I set it\'s \"Return Key\" to Done. This is a one line only input (so it wont need multiple lines).

How do I hide the virt

Answer 1

UITextView does not have any methods which will be called when the user hits the return key.

Even then if you want to do this, implement the textView:shouldChangeTextInRange:replacementText: method of UITextViewDelegate and in that check if the replacement text is \n, hide the keyboard.

There might be other ways but I am not aware of any.

Make sure you declare support for the UITextViewDelegate protocol.

- (BOOL)textView:(UITextView *)textView shouldChangeTextInRange:(NSRange)range 
replacementText:(NSString *)text {

    if([text isEqualToString:@"\n"]) {
        [textView resignFirstResponder];
        return NO;
    }
    return YES;
}

I hope it will helps a lot.
