Answer 1

If you want to know the desired height for a certain width , you can use the following code:

 NSString *yourString = @"My great text o0"; CGSize s = [yourString sizeWithFont:[UIFont systemFontOfSize:12] constrainedToSize:CGSizeMake(width, MAXFLOAT) lineBreakMode:UILineBreakModeWordWrap]; // s.height is your your height

Answer 2

 label.text = @"some text of random length"; [label sizeToFit]; 

If the text can be more than 1 line, add label.numberOfLines = 0; before calling sizeToFit;

Answer 3

try it

 NSString *sample = @"..."; CGSize txtSz = [sample sizeWithFont:[UIFont fontWithName: @"Helvetica" size: 16]]; CGRect lblFrame = CGRectMake(10,50, txtSz.width, txtSz.height); yourLabel.frame = lblFrame; 

Answer 4

It's 2016 and sizeWithFont long gone.

Now in Swift 3 use:

 let text = "Random Text" let size = (text as NSString).size(attributes: [NSFontAttributeName : UIFont.systemFont(ofSize: 50)]) let label = UILabel(frame: CGRect(x: 0, y: 0, width: size.width, height: size.height))
