UILabel *description; // fit framework to largest measurement you privation ... CGSize labelSize = [description.matter sizeWithFont:description.font constrainedToSize:description.framework.dimension lineBreakMode:description.lineBreakMode]; description.framework = CGRectMake( description.framework.root.x, description.framework.root.y, description.framework.measurement.width, labelSize.tallness);
Replace : Alternative for deprecated
sizeWithFont:constrainedToSize:lineBreakMode:Mention, Alternative for deprecated sizeWithFont: successful iOS 7?
CGSize labelSize = [description.matter sizeWithAttributes:@{NSFontAttributeName:description.font}]; description.framework = CGRectMake( description.framework.root.x, description.framework.root.y, description.framework.measurement.width, labelSize.tallness);
