iOS实现微信摇一摇动画

- (void)viewDidLoad {

    [superviewDidLoad];
    // Do any additional setup after loading the view, typically from a nib.
    self.view.layer.contents= (id)[UIImageimageNamed:@"ShakeforsongBgshade"].CGImage;
}

- (void)motionBegan:(UIEventSubtype)motion withEvent:(UIEvent*)event
{
    NSLog(@"摇一摇开始");
    CGFloatoffset =25;
    CABasicAnimation*animation = [CABasicAnimationanimationWithKeyPath:@"transform.translation.y"];

    animation.duration=1;
    animation.toValue=@(-offset);
    animation.autoreverses=YES;
    [self.topImageView.layeraddAnimation:animationforKey:nil];
    animation.toValue=@(offset);
    [self.bottomImageView.layeraddAnimation:animationforKey:nil];
}

#define kToDadian(x) (M_PI/180* (x))
