段控制的SelectedTintColor在iOS 13上不是圆角 [英] SelectedTintColor of Segment Control is not rounded corner on iOS 13

问题描述

圆角在iOS 12及以下版本上运行良好，但在iOS 13上已损坏.我创建了一个自定义的Segment控件类.

代码:

  class SegmentedControl:UISegmentedControl {覆盖func layoutSubviews(){super.layoutSubviews()layer.cornerRadius = self.bounds.size.height/2.0layer.borderColor = UIColor(红色:170.0/255.0，绿色:170.0/255.0，蓝色:170.0/255.0，alpha:1.0).cgColorlayer.borderWidth = 1.0layer.masksToBounds = trueclipsToBounds = true}} 

我已经看过这篇文章-

解决方案

我在iOS 13上遇到了同样的问题.然后，我深入研究了它的视图层次结构，然后发现它具有多个子视图.因此，我为iOS 13制作了一个技巧.您必须对iOS 13进行以下更改-

1. 将 selectedSegmentTintColor 更改为 Clear - self.selectedSegmentTintColor = .clear

2. 在 layoutSubviews -

   中添加以下代码段

     for i in 0 ... subviews.count-1 {如果让subview = subviews [i]为?UIImageView {如果i == self.selectedSegmentIndex {subview.backgroundColor = UIColor(红色:170.0/255.0，绿色:170.0/255.0，蓝色:170.0/255.0，alpha:1.0)}别的{subview.backgroundColor = .clear}}} 

希望它能对您有所帮助.

Rounded corner is working great on iOS 12 and below, but it's broken on iOS 13. I've created a custom Segment control class.

Code:

class SegmentedControl: UISegmentedControl {
    override func layoutSubviews() {
      super.layoutSubviews()
      layer.cornerRadius = self.bounds.size.height / 2.0
      layer.borderColor = UIColor(red: 170.0/255.0, green: 170.0/255.0, blue: 170.0/255.0, alpha: 1.0).cgColor
      layer.borderWidth = 1.0
      layer.masksToBounds = true
      clipsToBounds = true

   }
}

I've gone through this post - How to change the colors of a segment in a UISegmentedControl in iOS 13? but I couldn't get any solution.

解决方案

I was facing the same issue on iOS 13. Then I dug into its view hierarchy then I found it has multiple subviews. So I made a trick for iOS 13. You have to do following changes for iOS 13 -

1. ChangeselectedSegmentTintColor to Clear - self.selectedSegmentTintColor = .clear

2. Add following code snippet inside layoutSubviews -

   for i in 0...subviews.count - 1{
   
           if let subview = subviews[i] as? UIImageView{
   
               if i == self.selectedSegmentIndex {
   
                   subview.backgroundColor = UIColor(red: 170.0/255.0, green: 170.0/255.0, blue: 170.0/255.0, alpha: 1.0)
   
               }else{
   
                   subview.backgroundColor = .clear
               }
   
           }
       }
   

I hope it will help you.
