试试这个 -

CABasicAnimation* animation = [CABasicAnimation animationWithKeyPath:@"transform.rotation.z"];
animation.fromValue = [NSNumber numberWithFloat:0.0f];
animation.toValue = [NSNumber numberWithFloat: 2*M_PI];
animation.duration = 10.0f;
animation.repeatCount = INFINITY;
[self.yourImage.layer addAnimation:animation forKey:@"SpinAnimation"];
