CABasicAnimation 指针旋转动画的问题。

Studio
#1

CABasicAnimation* rotationAnimation = CABasicAnimation animationWithKeyPath:@"transform.rotation.z"];

rotationAnimation.toValue = NSNumber numberWithFloat:(DEGREES_TO_RADIANS(160))];

//rotationAnimation.toValue = ;

rotationAnimation.duration = 1.0f;

rotationAnimation.delegate = self;

rotationAnimation.autoreverses = NO; // Very convenient CA feature for an animation like this

rotationAnimation.timingFunction = CAMediaTimingFunction functionWithName:kCAMediaTimingFunctionEaseInEaseOut];

pinLayer addAnimation:rotationAnimation forKey:@"revItUpAnimation"];

这是一段让指针从起始位置旋转到目标位置的动画代码，但我现在的需求是希望指针能在目标位置停留，而不是回到原位置，我需要怎么修改，求助啊！谢谢大家了。

#2 
rotationAnimation.fillMode = kCAFillModeForwards;
rotationAnimation.removedOnCompletion = NO;
```

 

加上上面两句
