购物车的动画效果，这么简单的逻辑

    [UIViewanimateWithDuration:1.0animations:^{

        ImageView.frame=CGRectMake(ScreenWidth-55, -(screenHeight - CGRectGetHeight(self.view.frame) - 40), 0,0);

        ImageView.transform =CGAffineTransformRotate(ImageView.transform,M_PI);

    } completion:^(BOOL finished) {

        //动画完成后做的事

    }];
