我正在使用这行代码来执行segue
[self.window.rootViewController performSegueWithIdentifier:@"viewMessage" sender:self];
但是因为我正在呼叫rootViewController当我需要在viewMessage中寻找loginViewController friendsListTableViewController时，我试图在[self performSegueWithIdentifier:@"viewMessage" sender:self];中寻找@implementations标识符声明self，但我有两个JBSlidingTableViewCell1和performSeguqWithIdentifier一直认为是[friendsListTableViewController performSegueWithIdentifier:@"viewMessage" sender:self];，因为它是一个UITableView，它无法识别performSeguqWithIdentifier我试过friendsListTableViewController但我得到的是performSegueWithIdentifier不是该类的一部分，实际上它是一个UIViewController ......
我试图尽量避免发布代码，因为它有很多，但我只是想看看是否有办法强迫loginViewController指向我的//

鉴于您的应用程序的结构，似乎获取对friendsListTableViewController的引用的唯一方法是查找视图链。因为，nextResponder方法将返回它负责的视图的视图控制器，以下应该从自定义单元的实现文件中获取对所需视图控制器的引用：
self.superview.superview.nextResponder
在这种情况下，单元格的超级视图是表格视图，并且该表格视图位于控制器主视图的子视图中，因此self.superview.superview将您带到控制器的self.view。 nextResponder的文档说：“UIView通过返回管理它的UIViewController对象（如果有的话）来实现这个方法”。因此，在控制器的self.view上调用nextResponder会为您提供控制器。
