我想單擊一個按鈕來製作旋轉輪。我點擊了按鈕後旋轉了一個圓形圖像,並在一次旋轉後停止。現在我想顯示一個彈出窗口,顯示他得到了多少點。我打算用標籤來做到這一點。但我很困惑如何顯示彈出窗口。如何在Xcode,Swift3中循環旋轉UIImage後顯示彈出視圖?

您可以使用UIAlertViewController

下行樂3碼

var alert = UIAlertController() 

override func viewDidLoad() { 
    super.viewDidLoad() 
    self.alert = UIAlertController(title: "Congratulations!", message: "You have won 100 points", preferredStyle: .alert) 
    self.alert.addAction(UIAlertAction(title: "Done", style: .default, handler: {action in 
     switch action.style { 
     case .default: 
      //do your other stuff ahead after receiving points 
     case .cancel: 
      print("cancel") 
     case .destructive: 
      print("destruct") 
     }})) 
} 

//your rotation stopped 
//call the UIAlertViewController 
self.present(self.alert, animated: true, completion: nil)
