how do i let text fit to UIButton?
提问by CCC
problem:
问题：
Button size is enough, however when I change title, the title text cannot fit the button width. Any SDK function can solve this problem, or I need to manually code to solve it?
按钮大小足够了，但是当我更改标题时，标题文本无法适应按钮宽度。有什么SDK功能可以解决这个问题，还是需要自己手动编码才能解决？
Please refer to following pictures.
请参考以下图片。

when I change the title text
当我更改标题文本时
tried some ways before
之前试过一些方法
_button.titleLabel.adjustsFontSizeToFitWidth = YES;
the way will change my font size. I cannot accept the way.[_button setTitleEdgeInsets:UIEdgeInsetsMake(10.0, 10.0, 0.0,0.0)];
the way change label's position only, not label size.[_button.titleLabel sizeToFit];
result is same with picture(3).[_button sizeToFit];
title moved to upper left corner, and the title still the same result.
_button.titleLabel.adjustsFontSizeToFitWidth = YES;
方式会改变我的字体大小。我不能接受这种方式。[_button setTitleEdgeInsets:UIEdgeInsetsMake(10.0, 10.0, 0.0,0.0)];
这种方式只改变标签的位置，而不是标签大小。[_button.titleLabel sizeToFit];
结果与图（3）相同。[_button sizeToFit];
标题移到左上角，标题还是一样的结果。
Just confused, my button size is big enough, why title size is so small?
只是困惑，我的按钮大小足够大，为什么标题大小如此之小？

For people who come across with this question:
对于遇到这个问题的人：
Try using the setter:
尝试使用 setter：
[self.myButton setTitle:@"Title" forState:UIControlStateNormal];
[self.myButton sizeToFit];

Make sure also that the label doesn't adjust later spacing, as that seems to take precedence over adjusting font size. Also make sure the minimumScaleFactor < 1.
还要确保标签不会在以后调整间距，因为这似乎优先于调整字体大小。还要确保 minimumScaleFactor < 1。
button.titleLabel.adjustsFontSizeToFitWidth = YES;
button.titleLabel.adjustsLetterSpacingToFitWidth = NO;
button.titleLabel.minimumScaleFactor = 0.5;

Here is the Swift version:
这是 Swift 版本：
let button = UIButton()
button.titleLabel?.numberOfLines = 1
button.titleLabel?.adjustsFontSizeToFitWidth = true
button.titleLabel?.lineBreakMode = NSLineBreakMode.ByClipping

In IB, just select the button, go to the editor menu, and choose "Size To Fit Content"
在 IB 中，只需选择按钮，转到编辑器菜单，然后选择“大小以适合内容”
