Shrink title label text of UIButton when it reaches max number of lines

I have a UIButton that I want resizing the text font depending on the size of the NSString. I want the maximum number of lines to be 3 and if the NSString length exceeds 3 lines then the font shrinks until all the text is shown. This is what I have so far:

button.titleLabel.textAlignment = NSTextAlignmentCenter;
button.titleLabel.lineBreakMode = NSLineBreakByWordWrapping;

button.titleLabel.adjustsFontSizeToFitWidth = YES;
button.titleLabel.numberOfLines = 3;

However this code does not do as I please; the UIButton text contains ... if the NSString exceeds 3 lines. Any ideas?

It is a bug to set the lineBreakMode when you want to the text to shrink. Just remove the line that sets lineBreakMode and it will work.

You also need to set the minimumScaleFactor of the label. The default is 0.
