objective-c - 使用自定义表格 View 单元格中的按钮

Question

我在自定义表格 View 单元格中有一个类似于 facebook 的按钮。在我的 tableview 类中，我有以下函数。

- (IBAction)sendLike:(id)sender
          WithString: (NSString *)shareString
              andUrl:(NSURL *)shareUrl{

          //Do all kinds of things


        [fbController setInitialText:shareString];
        [fbController addURL:shareUrl];
        [fbController setCompletionHandler:completionHandler];
        [self presentViewController:fbController animated:YES completion:nil];
    }
}

在我的 cellForRowAtIndexpath 中，我尝试按以下方式调用此方法。

 NSString *shareString = video.name;
        NSURL *shareUrl = [NSURL URLWithString:video.url];
        [cell.facebook addTarget:self action:@selector(sendLike: WithString:shareString andUrl:shareUrl)
                 forControlEvents:UIControlEventTouchUpInside];

但它提示我应该在我的@selector 中放置':'。有人可以帮忙吗？

提前致谢。

你可以这样试试

cell.facebook.tag = indexPath.row.
    [cell.facebook addTarget:self action:@selector(sendLike:)
                     forControlEvents:UIControlEventTouchUpInside];

在sendLike事件中

- (IBAction)sendLike:(id)sender
  {


        //if you want to fetch data from any list then try
        //UIButton *selectedButton = (UIButton*)sender;
        //data = [dataList objectAtIndex:selectedButton.tag];
        NSString *shareString = video.name;
        NSURL *shareUrl = [NSURL URLWithString:video.url];

        [fbController setInitialText:shareString];
        [fbController addURL:shareUrl];
        [fbController setCompletionHandler:completionHandler];
        [self presentViewController:fbController animated:YES completion:nil];
    }
