在iOS 8中更改UISegmentedControl的边框宽度

Question

如何在iOS 8中更改UISegmentedControl的边框宽度？目前，边框宽度为2px，我想将其设置为1px。设置CALayer的边框宽度似乎不起作用。我似乎无法在任何地方找到任何相关信息。

提前感谢您的帮助！

Answer 1

适用于iOS 8.1

   _segmentedControl.layer.borderWidth = 2;

Answer 2

我建议您根据需要使用自定义分割器图像：

[mySegmentedControl setDividerImage:image1 forLeftSegmentState:UIControlStateNormal                   rightSegmentState:UIControlStateNormal barMetrics:barMetrics];
[mySegmentedControl setDividerImage:image2 forLeftSegmentState:UIControlStateSelected                   rightSegmentState:UIControlStateNormal barMetrics:barMetrics];
[mySegmentedControl setDividerImage:image3 forLeftSegmentState:UIControlStateNormal                   rightSegmentState:UIControlStateSelected barMetrics:barMetrics];
