Iphone – UITextView with “Done” button *and* “Return” key

Figured I would post the snippet right here instead:

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;
}

Swift 4.0 update:

func textView(_ textView: UITextView, shouldChangeTextIn range: NSRange, replacementText text: String) -> Bool {
    if text == "\n" {
        textView.resignFirstResponder()
        return false
    }
    return true
}

UITextField and UITextView both have a text property that you can use to retrieve the string values. For example,

NSString *string = [NSString stringWithFormat:@"%@, %@", textField.text, textView.text];

Keep in mind you'll probably want to examine the strings to make sure they're not empty or contain invalid characters before putting them into a URL.
