Dynamically getting height of UILabel according to

Question

I am using the this method for getting the height of the UILabel Dynamically:

+(CGSize) GetSizeOfLabelForGivenText:(UILabel*)label Font:(UIFont*)fontForLabel Size:  (CGSize)LabelSize{
    label.numberOfLines = 0;
    CGSize labelSize = [label.text sizeWithFont:fontForLabel constrainedToSize:LabelSize lineBreakMode:NSLineBreakByCharWrapping];
    return (labelSize);
}

With this solution I am getting the exact size of UILabel if my code is running on below iOS 8 but if I run my application on iOS7 then it is returns a different value.

The method sizeWithFont:constrainedToSize:lineBreakMode: is deprecated in iOS7. You should use sizeWithAttributes: instead.

Example:

NSDictionary *fontAttributes = @{NSFontAttributeName : [UIFont systemFontOfSize:15]};
CGSize textSize = [self.myLabel.text sizeWithAttributes:fontAttributes];
CGFloat textWidth = textSize.width;
CGFloat textHeight = textSize.height;
