iOS 7 sizeWithAttributes: replacement for sizeWithFont:constrainedToSize

well you can try this :

NSDictionary *attributes = @{NSFontAttributeName: [UIFont fontWithName:@"HelveticaNeue" size:14]};// NSString class method: boundingRectWithSize:options:attributes:context is// available only on ios7.0 sdk.CGRect rect = [textToMeasure boundingRectWithSize:CGSizeMake(width, CGFLOAT_MAX)                                          options:NSStringDrawingUsesLineFragmentOrigin                                       attributes:attributes                                          context:nil];

This is how I did it:

    // Get a font to draw it inUIFont *font = [UIFont boldSystemFontOfSize: 28];CGRect textRect;NSDictionary *attributes = @{NSFontAttributeName: font};// How big is this string when drawn in this font?textRect.size = [text sizeWithAttributes:attributes];// Draw the string[text drawInRect:textRect withAttributes:attributes];

Here's my method to deal with both situations, goes in an NSString category.

- (CGSize) sizeWithFontOrAttributes:(UIFont *) font {    if (IS_IOS7) {        NSDictionary *fontWithAttributes = @{NSFontAttributeName:font};        return [self sizeWithAttributes:fontWithAttributes];    } else {        return [self sizeWithFont:font];    }}
