@IBOutlet weak var selectorSemiView: UIView! 
@IBOutlet weak var blurEffect: UIVisualEffectView! 
@IBOutlet var outerAreaRecognizer: UITapGestureRecognizer! 
override func viewDidLoad() { 
    super.viewDidLoad() 
    selectorSemiView.layer.cornerRadius = 15 
    selectorSemiView.layer.shadowColor = UIColor.gray.cgColor 
    selectorSemiView.layer.shadowOffset = CGSize.zero 
    selectorSemiView.layer.shadowRadius = 7 

}

selectorSemiView是一個容器視圖UIView的陰影，cornerradius不工作

當我運行這個程序，沒有陰影，沒有圓角。

我的代碼有什麼問題？

你的代碼是好的，但你忘了設置不透明度，如果您需要了解更多信息，你可以得到另一個答案在SO，對於如

selectorSemiView.layer.cornerRadius = 15 
    selectorSemiView.layer.shadowColor = UIColor.gray.cgColor 
    selectorSemiView.layer.shadowOffset = CGSize.zero 
    selectorSemiView.layer.shadowOpacity = 1.0 
    selectorSemiView.layer.shadowRadius = 7.0 
    selectorSemiView.layer.masksToBounds = false
