堆栈视图内部的视图不'；t在iOS中正确显示（Swift）

我试图创建一个包含视图的水平堆栈视图。下面是我的代码，它不能正常工作。此外，角半径未应用于视图

        tag_stack.spacing = 30
        tag_stack.translatesAutoresizingMaskIntoConstraints = false
        tag_stack.axis = .horizontal
        stack_scroll.addSubview(tag_stack)
        
        for views in selected{
           
            let holder_view = UILabel()
            let container = UIView()
            
            container.translatesAutoresizingMaskIntoConstraints = false
            holder_view.translatesAutoresizingMaskIntoConstraints = false
            
            container.heightAnchor.constraint(equalToConstant: 25).isActive = true
            container.backgroundColor = UIColor(red: 47/255, green: 175/255, blue: 249/255, alpha: 1.0)
            container.layer.cornerRadius = 12.5
            
            container.addSubview(holder_view)
           
            holder_view.font = UIFont.systemFont(ofSize: 12)
            holder_view.textColor = .white
            holder_view.centerYAnchor.constraint(equalTo: container.centerYAnchor, constant: 0).isActive = true
            holder_view.leadingAnchor.constraint(equalTo: container.leadingAnchor, constant: 5).isActive = true
            holder_view.trailingAnchor.constraint(equalTo: container.trailingAnchor, constant: -5).isActive = true
            holder_view.text = views

            tag_stack.addArrangedSubview(container)
        }
        tag_stack.leadingAnchor.constraint(equalTo: stack_scroll.leadingAnchor).isActive = true
        tag_stack.trailingAnchor.constraint(equalTo: stack_scroll.trailingAnchor).isActive = true````

您似乎忘记设置所需的属性。不要忘记为所需视图添加

view.clipsToBounds=false

和

view.layer.cornerRadius=x

。

您忘记添加所需的属性，只需转到“属性”和“查看”属性，并检查clipsToBound是否绑定了控件，或者您可以通过添加一行代码来解决此问题，只需添加

if (view.clipsToBound == true){
 view.clipsToBound = false 
}

我知道拐角半径不适用。重写此函数“viewDidLayoutSubviews（）”并尝试在此处设置container.layer.cornerRadius。
