Thank you for that. Is there any way to truncate multiline text? I mean adding to your category method like - (NSString*)stringByTruncatingToSize:(CGSize)size withFont:(UIFont *)font; Is it possible? Thanks in advance. Hello. Thank you for that. Is there any way to truncate multiline text?

I've updated the code to check for the string length up front. Krille, thanks for pointing that out. I’ve updated the code to check for the string length up front.

I have a problem with this implementation: Strings are cut, even if they are narrower than the defined maximum width: Example: cell.textLabel.text = [news stringByTruncatingToWidth:240 withFont:[UIFont boldSystemFontOfSize:15]]; So every String is at least missing the last character and gets the ellipsis appended... "Here is a superlong Title to..." -> correct "Short Titl..." -> wrong Cheers Krille Thank you for this post!

By standard naming conventions, it should not. You might want to generalize the string to be appended. - (NSString*)stringByTruncatingStringToWidth:(CGFloat)width withFont:(UIFont *)font endingWith:(NSString*)endString { /* your implementation but using endString */ } and implement your function as - (NSString*)stringByTruncatingStringToWidth:(CGFloat)width withFont:(UIFont *)font { [self stringByTruncatingStringToWidth: width withFont: font endingWith: ellipsis]; } But that's just a small tweak. Does NSString mutableCopy really return a string that needs to be released? By standard naming conventions, it should not.

- (NSString*)stringByTruncatingStringToWidth:(CGFloat)width withFont:(UIFont *)font endingWith:(NSString*)endString { /* your implementation but using endString */ }

and implement your function as

- (NSString*)stringByTruncatingStringToWidth:(CGFloat)width withFont:(UIFont *)font
{
[self stringByTruncatingStringToWidth: width withFont: font endingWith: ellipsis];
}

But that’s just a small tweak.
