topViewController：无法识别的select器错误与custome segue导航控制器

我试图从这个github解决scheme使用“Slideout Sidebar”。

这是我的故事板：

我使用惰性加载方法为我的Uicollectionview在我的委托

代码我有这个：

ParseOperation *weakParser = parser; parser.completionBlock = ^(void) { if (weakParser.appRecordList) { dispatch_async(dispatch_get_main_queue(), ^{ myCollectionViewController *rootViewControllers = (myCollectionViewController*)[(UINavigationController*)self.window.rootViewController topViewController]; [weakParser.appRecordList valueForKey:@"id"]); rootViewControllers.entries = weakParser.appRecordList; if(weakParser.appRecordList == nil) NSLog(@"weakParser.appRecordList is nill"); if(weakParser.appRecordList != nil) NSLog(@"weakParser.appRecordList is Not nil l"); [rootViewControllers.collectionView reloadData]; }); } 

如果我修改后运行我的项目，它会返回这个错误：

如果我注释掉Parsoperation中的代码段，视图和滑动条完美的工作，但collectionview新数据没有显示，所以我想修改后的topcontroller不再是“topViewController”。

我尝试了这个代码块内的客户继续，但没有发生：

  UIStoryboardSegue * segue; UINavigationController *navController = (UINavigationController*)[segue destinationViewController]; myCollectionViewController *rootViewControllers = (myCollectionViewController*)[navController topViewController]; 

也尝试过这一个（有收集视图的类里面的数据，但是没有调用数目的函数）：

  ParseOperation *weakParser = parser; UIStoryboard *mainStoryboard = [UIStoryboard storyboardWithName:@"MainStoryboard" bundle: nil]; myCollectionViewController *svc =[mainStoryboard instantiateViewControllerWithIdentifier:@"MainCategory"]; parser.completionBlock = ^(void) { if (weakParser.appRecordList) { dispatch_async(dispatch_get_main_queue(), ^{ svc.entries = weakParser.appRecordList; [svc.collectionView reloadData]; }); }
