My button's titleLabel become “…” on iOS10

问题:

When I use iOS 10 some button label's text become "...". I found the same string (e.x:我是人) in iOS9 uses 48 width. In iOS10 it uses 48.96 width. How to fix?

You have to use "adjustsFontSizeToFitWidth" property of titleLabel of your button

Example:

  myButton.titleLabel.adjustsFontSizeToFitWidth = YES;

This line will automatically adjust font size for the text of myButton based on the width of the button.

Use this link: adjust UIButton font size to width

Another solution is to increase the width of the button, by adjusting constraints.
