The method -sizeWithFont:constrainedToSize:lineBreakMode is now deprecated. You will want to use the method -boundingRectWithSize:options:attributes:context: now.

Here's an examples:

CGSize boundingRectSize = CGSizeMake(widthToConstrainTo, CGFLOAT_MAX);
NSDictionary *attributes = @{NSFontAttributeName : [UIFont fontWithName:fontName size:14]};
CGRect labelSize = [labelString boundingRectWithSize:boundingRectSize options:NSStringDrawingUsesLineFragmentOrigin | NSStringDrawingUsesFontLeading
                                                attributes:attributes
                                                   context:nil];

In the above example I know the width I want to constrain the label to but since I'm not sure of the height, I just max the height param out using CGFLOAT_MAX. For the options you need to use NSStringDrawingUsesLineFragmentOrigin and NSStringDrawingUsesFontLeading if you're trying to calculate the size a label that can be any number of lines.
