尝试动画MKAnnotationView时应用程序崩溃

Question

在线几个示例后，我试图为MKAnnotationView创建动画。我已经放置在init下面的代码（）我MKAnnotationView子类：

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) 

只要注解视图被添加到地图，应用程序崩溃，但以下情况除外：

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:]' 

任何想法我做错了什么？

谢谢！

由于控制台建议，你应该使用：

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 :)
