你说你是在异步填充内容但你是否在主线程的上下文中调用reloadData？ （而不是通过填充内容的主题）

You said you're populating content asynchronously but did you invoke the reloadData in the context of the main thread ? (and not via the thread that populates the content)

Objective-C

[yourUITableView performSelectorOnMainThread:@selector(reloadData)
                                  withObject:nil 
                               waitUntilDone:NO];

Swift

dispatch_async(dispatch_get_main_queue(), { self.tableView.reloadData() })

Monotouch

InvokeOnMainThread(() => this.TableView.ReloadData());
