iOS 7 sizeWithAttributes: replacement for sizeWithFont:constrainedToSize

How do you return a multiline text CGSize from the new iOS 7 method sizeWithAttributes?

I would like this to produce the same results as sizeWithFont:constrainedToSize.

NSString *text = @"Lorem ipsum dolor sit amet, consectetur adipiscing elit. Phasellus eu urna quis lacus imperdiet scelerisque a nec neque. Mauris eget feugiat augue, vitae porttitor mi. Curabitur vitae sollicitudin augue. Donec id sapien eros. Proin consequat tellus in vehicula sagittis. Morbi sed felis a nibh hendrerit hendrerit. Lorem ipsum dolor sit."

CGSize textSize = [text sizeWithAttributes:@{ NSFontAttributeName : [UIFont fontWithName:@"HelveticaNeue-Light" size:16.0] }];

This method only produces the height for a single line of text.

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)
