Replacement for deprecated sizeWithFont: in iOS 7?

by

Use sizeWithAttributes: instead, which now takes an NSDictionary. Pass in the pair with key UITextAttributeFont and your font object like this:

CGRect rawRect = {};
rawRect.size = [string sizeWithAttributes: @{
    NSFontAttributeName: [UIFont systemFontOfSize:17.0f],
}];

// Values are fractional -- you should take the ceil to get equivalent values
CGSize adjustedSize = CGRectIntegral(rawRect).size;
