NSString sizeWithFont: for multiple lines?

Question

Is there an equivalent to NSString's sizeWithFont: method that can be used for calculating the height of text in a UITectView for a given width? All of the methods from NSString only operate on a single line from what I can tell.

Answer 1

From Apple's reference for these NSString methods, you could use -sizeWithFont:constrainedToSize: or -sizeWithFont:constrainedToSize:lineBreakMode: for "Computing Metrics for Multiple Lines of Text".

CGSize size = [theString sizeWithFont:font
                    constrainedToSize:CGSizeMake(width, 100000)];
return size.height;
