如何使UILabel在字符边界处截断？

Question

I have some UILabels next to each other horizontally which will contain names.

I can't find any way of getting the text to be truncated at a character boundary - I've tried a line break mode with NSLineBreakByCharWrapping but the characters get chopped off in the middle

I've tried the other line break modes but can't get rid of the partial character (x in this particular example), I don't want part of a character displayed obviously as it looks no good.

Its not feasible to limit the output to a hard coded number of characters because iiiiiiii is a totally different width to wwwwwwww for example. Also I don't want … appearing within the text because as its narrow then there would be too few characters left if part of the available space is consumed with ...

    contactItem.name.frame = nameFrame;
    contactItem.name.font = [UIFont systemFontOfSize:12];
    contactItem.name.textColor = [UIColor whiteColor];
    contactItem.name.textAlignment = NSTextAlignmentCenter;
    contactItem.name.lineBreakMode = NSLineBreakByCharWrapping;
    [self.scrollView addSubview: contactItem.name];

contactItem.name is the UILabel(s). nameFrame is getting horizontally incremented for each contactItem.

Maybe calculate text size yourself and react when it's too long?

Calculating UILabel Text Size

I don't know if this the simplest solution for this problem - but for sure it's the working solution.
