How to add Done button to the keyboard?

Question

UPDATE:

I also tried implementing UITextViewDelegate delegate and then doing in my controller:

- (BOOL)textViewShouldEndEditing:(UITextView *)textVie         


        

Answer 1

Ok, so I too have been struggling with this very issue. Currently I am accessing a UITextView in a UITableViewCell (via Tags). Because I am using prototype cells I cannot use IBActions nor IBOutlets like everyone suggests. Instead, I am using;

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

This will then provide me with the text each time the user hits a button. My solution then, was to get the ascii character for new line; "/n". If that is the text that was entered, I would resign the first responder. For example;

// If the text length is 0 then the user is deleting something, so only check the ascii character if there is text to check
if (text.length != 0) {
    // Get the Ascii character
    int asciiCode = [text characterAtIndex:0];
    // If the ascii code is /n or new line, then resign first responder
    if (asciiCode == 10) {
        [alertTextView resignFirstResponder];
        [DeviceTextView resignFirstResponder];
    }
}

Not sure if anyone else will need this hacky solution but I figured I'd put it out there in case someone needs it!
