Answer 1

Implement the shouldChangeTextInRange: delegate method.

Use below approach and the solution work only with @"\n" (new line character).

//In you *.h file make sure you add
@interface v1ViewController : UIViewController 

- (void)viewDidLoad
{
    [super viewDidLoad];
    // Do any additional setup after loading the view, typically from a nib.

    myTextField.delegate = self;
}

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

            if ([text isEqualToString:@"\n"]) {

                [textView resignFirstResponder];
                // Return FALSE so that the final '\n' character doesn't get added
                return NO;
            }
            // For any other character return TRUE so that the text gets added to the view
            return YES;
    }
