在objective c中从左向右滑动之后，UIView动画侧视图从右向左滑动

// 创建侧视图和主视图
UIView *sideView = [[UIView alloc] initWithFrame:CGRectMake(CGRectGetWidth(parentView.frame), 0, sideViewWidth, CGRectGetHeight(parentView.frame))];
UIView *mainView = [[UIView alloc] initWithFrame:CGRectMake(0, 0, CGRectGetWidth(parentView.frame), CGRectGetHeight(parentView.frame))];

// 将侧视图和主视图添加到父视图中
[parentView addSubview:sideView];
[parentView addSubview:mainView];

// 添加滑动手势
UISwipeGestureRecognizer *swipeGesture = [[UISwipeGestureRecognizer alloc] initWithTarget:self action:@selector(handleSwipe:)];
[mainView addGestureRecognizer:swipeGesture];

// 滑动手势的回调方法
- (void)handleSwipe:(UISwipeGestureRecognizer *)gesture {
    // 从左向右滑动
    if (gesture.direction == UISwipeGestureRecognizerDirectionRight) {
        // 使用UIView的动画功能实现侧视图从右向左滑动的效果
        [UIView animateWithDuration:0.3 animations:^{
            // 设置侧视图的新位置
            sideView.frame = CGRectMake(CGRectGetWidth(parentView.frame) - sideViewWidth, 0, sideViewWidth, CGRectGetHeight(parentView.frame));
        }];
    }
}
