UITableViewCellContentView 上的 shouldReceiveTouch

shouldReceiveTouch on UITableViewCellContentView(UITableViewCellContentView 上的 shouldReceiveTouch)

问题描述

我正在尝试忽略 UITableView 上的 UITapGestureRecognizer 轻按以下内容:

I'm trying to ignore UITapGestureRecognizer taps on a UITableView with the following:

- (BOOL)gestureRecognizer:(UIGestureRecognizer *)gestureRecognizer shouldReceiveTouch:(UITouch *)touch {
      if ([touch.view isKindOfClass:[UITableViewCellContentView class]]) {
          return NO; // ignore the touch
      }
      return YES; // handle the touch
}

它不会编译:使用未声明的标识符'UITableViewCellContentView'

It won't compile: "Use of undeclared identifier 'UITableViewCellContentView'

无证类?需要子类?更好的方法来实现这一点?

Undocumented class? Need to subclass? Better way to accomplish this?

感谢您的帮助.

推荐答案

好像可以这样:

- (BOOL)gestureRecognizer:(UIGestureRecognizer *)gestureRecognizer shouldReceiveTouch:(UITouch *)touch {
    if([touch.view isKindOfClass:[UITableViewCell class]]) {
         return NO;
    }
    // UITableViewCellContentView => UITableViewCell
    if([touch.view.superview isKindOfClass:[UITableViewCell class]]) {
         return NO;
    }
    // UITableViewCellContentView => UITableViewCellScrollView => UITableViewCell
    if([touch.view.superview.superview isKindOfClass:[UITableViewCell class]]) {
         return NO;
    }
    return YES; // handle the touch
}
