最近看到了用户的头像可以前后旋转，还是蛮酷炫的就写了段实现方法，给需要帮助的人吧。

// 头像动画    [self rotate360WithDuration:2.0 repeatCount:1];    _headImageView.animationDuration = 2.0;    _headImageView.animationImages = [NSArray arrayWithObjects:[UIImage imageNamed:@"profileFansV2"],                                      [UIImage imageNamed:@"profileCartListV2"],[UIImage imageNamed:@"profileCartListV2"],                                      [UIImage imageNamed:@"profileCartListV2"],[UIImage imageNamed:@"profileCartListV2"],                                      [UIImage imageNamed:@"profileFansV2"], nil];    _headImageView.animationRepeatCount = 1;    [_headImageView startAnimating];

- (void)rotate360WithDuration:(CGFloat)aDuration repeatCount:(CGFloat)aRepeatCount{    CAKeyframeAnimation *theAnimation = [CAKeyframeAnimation animation];    theAnimation.values = [NSArray arrayWithObjects:                           [NSValue valueWithCATransform3D:CATransform3DMakeRotation(0, 0,1,0)],                           [NSValue valueWithCATransform3D:CATransform3DMakeRotation(M_PI, 0,1,0)],                           [NSValue valueWithCATransform3D:CATransform3DMakeRotation(M_PI, 0,1,0)],                           [NSValue valueWithCATransform3D:CATransform3DMakeRotation(2*M_PI, 0,1,0)],                           nil];    theAnimation.cumulative = YES;    theAnimation.duration = aDuration;    theAnimation.repeatCount = aRepeatCount;    theAnimation.removedOnCompletion = YES;       [_headImageView.layer addAnimation:theAnimation forKey:@"transform"];}
