Swift 3按钮文本自动调整大小 [英] Swift 3 Button text auto resizing

问题描述

所以我有基于设备自动调整大小的按钮，我想知道如何使按钮文本自行调整大小，就像具有最小尺寸或比例的UILable一样。

So I have buttons that auto resize based on device and I was wondering how I could make the button text resize on its own like a UILable with the minimum size or scale.

推荐答案

正如Matt所说UIButton标题与UILabel一起显示，您可以使用minimumScaleFactor和adjustsFontSizeToFitWidth等属性，这样字体就会根据可用的大小和内容调整大小已经。

As Matt said above UIButton title is displayed with UILabel, you could use properties such as minimumScaleFactor and adjustsFontSizeToFitWidth, such that the font resizes based on the size that is available and content that it has.

button.titleLabel.minimumScaleFactor = 0.5;
button.titleLabel.adjustsFontSizeToFitWidth = true;
