好的，这是我目前在我的应用程序中所拥有的，主视图具有包含不同任务的tableview。当你触摸它时，它会推送到DetailViewController。我一直在尝试在detailview中制作内部tableview。所以我现在有一个TableController但是现在当我点击一个任务它就冻结了。

self.navigationItem.rightBarButtonItem = addButton;
self.navigationItem.leftBarButtonItem = self.editButtonItem;
//self.navigationItem.rightBarButtonItem = addButton;

如果它有任何构建内部表的东西，这不起作用。

我认为问题可能出在DetailedViewController中的viewDidLoad方法中。修复以下两件事，看看是否有所作为。
这是你的代码，经过调整：
- (void)viewDidLoad
{
[super viewDidLoad];
if(selectedAction isEqualToString: @"details")
{
self.navigationItem.title = @"Task Details";
//lblText.text = selectedTask;
}
else if (selectedAction isEqualToString: @"add")
{
self.navigationItem.title = @"Add Task";
//lblText.text = selectedTask;
}
}
