嘗試動畫MKAnnotationView時應用程序崩潰

Question

在線幾個示例後，我試圖爲MKAnnotationView創建動畫。我已經放置在init下面的代碼（）我MKAnnotationView子類：

UIView.animate(withDuration: 10.0, delay: 0.0, options: .repeat, animations: {    
    UIView.addKeyframe(withRelativeStartTime: 0.0, relativeDuration: 0.5, animations: { 
     self.frame = biggerFrame 
    }) 

    UIView.addKeyframe(withRelativeStartTime: 0.5, relativeDuration: 0.5, animations: { 
     self.frame = originalFrame 
     }) 
}, completion: nil) 

只要註解視圖被添加到地圖，應用程序崩潰，但以下情況除外：

2016-09-25 19:32:58.655 MyApp 42[62332:4524529] *** Terminating app due to uncaught exception 'NSInternalInconsistencyException', reason: '+[UIView addKeyframeWithStartTime:duration:animations:] must be called inside the animations block of +[UIView animateKeyframesWithDuration:delay:options:animations:completion:]' 

任何想法我做錯了什麼？

謝謝！

由於控制檯建議，你應該使用：

UIView.animateKeyframes(withDuration: TimeInterval, delay: TimeInterval, options: UIViewKeyframeAnimationOptions, animations: { 
    your animation here 
    }, completion: nil) 

，而不是:)

目前，您正在使用的UIView。 animate（withDuration：delay：Option：animations：Completion :)
