IOS15之轻扫手势

ios中的手势，也是重点内容，必须学会使用。常见的有7大手势，今天介绍轻扫手势

    UISwipeGestureRecognizer *swipeGes = [[UISwipeGestureRecognizer alloc] init];
    swipeGes.direction = UISwipeGestureRecognizerDirectionLeft;
    [self.tableView addGestureRecognizer:swipeGes];
    [swipeGes addTarget:self action:@selector(swipe)];
}
-(void)swipe{
    NSLog(@"%s",__func__);
}

给tableView添加轻扫手势，方向向左。

其写法跟 给UIButton 添加 事件差不多。

swift 写法:

override func viewDidLoad() {
        super.viewDidLoad()
        let swipe = UISwipeGestureRecognizer(target: self, action: #selector(swipeClick))
        swipe.direction =  .left
        view.addGestureRecognizer(swipe)
    }
    @objc private func swipeClick() -> Void {
        debugPrint("swipeClick")
    }

swift写法更加优雅简洁。
