What is the best way to show multiple lines text in the UILabel?

CGRect currentFrame = myLabel.frame; CGSize max = CGSizeMake(myLabel.frame.size.width, 500); label.font = [UIFont systemFontOfSize:13.0]; CGSize expected = [myString sizeWithFont:myLabel.font]; myLabel.numberOfLines = 0;

CGRect currentFrame = myLabel.frame; CGSize max = CGSizeMake(myLabel.frame.size.width, -1); CGSize expected = [myString sizeWithFont:myLabel.font]; myLabel.numberOfLines = -1;

myLabel.numberOfLines = 0; CGRect currentFrame = myLabel.frame; CGSize max = CGSizeMake(myLabel.frame.size.width, 500); CGSize expected = [myString sizeWithFont:myLabel.font constrainedToSize:max lineBreakMode:myLabel.lineBreakMode]; currentFrame.size.height = expected.height; myLabel.frame = currentFrame;

You have to use UITextView for this purpose, otherwise Apple will rejects your app submission
