我使用这段代码来旋转任何View:funcrotateAnimation(theView:UIView,duration:CFTimeInterval=20.0,repeatCount:Float=200,toValue:CGFloat=CGFloat(.pi*2.0)){letrotateAnimation=CABasicAnimation(keyPath:"transform.rotation")rotateAnimation.fromValue=0.0rotateAnimation.toValue=toValuerotateAnimation.duration=durationr

我有什么我有一个箭头图像(如左图)。当用户点击它时，它应该会随着动画旋转180度，并且应该看起来像正确的。我做了什么privatevoidrotate(floatdegree,finalinttoggleV){finalRotateAnimationrotateAnim=newRotateAnimation(0.0f,degree,RotateAnimation.RELATIVE_TO_SELF,0.5f,RotateAnimation.RELATIVE_TO_SELF,0.5f);rotateAnim.setDuration(500);toggle.startAnimation(ro
