You just need to set frame in center of the screen ... change your one line code with it -

title = [[UILabel alloc] initWithFrame:CGRectMake(self.view.frame.size.width/2 - 200,self.view.frame.size.height/2 - 100,400,200)];

now your label is shown in the center of screen .. This will help you change the frame according to your use...

Has Hardik Thakkar said, the best way would be to use the center method. That way, even if your label would grow, it will always be centred.

UILabel *label = [[UILabel alloc] initWithFrame:CGRectMake(300,200,400,200)];
label.text = @"something";
label.center = self.view.center; (this should always be you superview)

Now, even if your label is bigger than the size you were expecting, it will always be centred
