 闪烁的view 动画

- (void) shakeToShow:(UIView*)aView{

    CAKeyframeAnimation* animation = [CAKeyframeAnimationanimationWithKeyPath:@"transform"];

    animation.duration =0.5;

    

    NSMutableArray *values = [NSMutableArrayarray];

    [values addObject:[NSValuevalueWithCATransform3D:CATransform3DMakeScale(0.1,0.1,
1.0)]];

    [values addObject:[NSValuevalueWithCATransform3D:CATransform3DMakeScale(1.2,1.2,
1.0)]];

    [values addObject:[NSValuevalueWithCATransform3D:CATransform3DMakeScale(0.9,0.9,
1.0)]];

    [values addObject:[NSValuevalueWithCATransform3D:CATransform3DMakeScale(1.0,1.0,
1.0)]];

    animation.values = values;

    [aView.layeraddAnimation:animation
forKey:nil];
