In UILabel there’s functionality to truncate labels using different truncation techniques (UILineBreakMode). In NSString UIKit Additions there is a similar functionality for drawing strings.

However, I found no way to access the actual truncated string. Is there any other way to get a truncated string based on the (graphical) width for a given font?

I’d like to have a category on NSString with this method:

-(NSString*)stringByTruncatingStringWithFont:(UIFont *)font forWidth:(CGFloat)width lineBreakMode:(UILineBreakMode)lineBreakMode

    One option is trying different sizes by looping until you get the right width. I.e. start with the full string, if that’s wider than what you need, replace the last two characters with an ellipsis character. Loop until it’s narrow enough.

    If you think you’ll be working with long strings, you can binary search your way towards the truncation point to make it a bit faster.
