myLabel.lineBreakMode = UILineBreakModeWordWrap;
myLabel.numberOfLines = 0;
myLabel.text = @"Some \n dynamic \n multiline \n text";
[myLabel sizeToFit]; // This shrinks the 9999 down to the size of the text
NSLog(@"Actual height is: %f", myLabel.frame.size.height); // Use this for spacing any further elements
[self.view addSubview:title]; // Or add it to a scroll view, or whatever...
