使用snapkit设置autolayout后,iOS框架出错

我在UIStoryboard中添加了一个UIView并将其绑定到一个名为testView的自定义UIView类,接下来,我在requireView函数的textView中创建了一个名为subView的UIView,

这是我的一步

1初始化subView

2将新的子视图添加到textView

3设置自动布局

4 set cornerRadius(view.frame.height / 2)

运行应用程序后,cornerRadius不会更改

然后我尝试打印subView的框架,得到(0,0)

这是我的代码

required init?(coder aDecoder: NSCoder) {
   super.init(coder: aDecoder)

   circelView = UIView()
   self.addSubview(circelView)
   circelView.snp_makeConsTraints(closure: { (makE) -> Void in
       make.size.equalTo(80)
       make.top.equalTo(self.snp_top)
       make.right.equalTo(self.snp_right)
   })
   print(circelView.framE) //get wrong frame
   circelView.layer.cornerRadius = circelView.frame.size.height / 2
   circelView.layer.masksToBounds = true
}

override func viewDidLayoutSubviews() {
    print(circelView.framE) // The frame will have been set
    circelView.layer.cornerRadius = circelView.frame.size.height / 2
}
