在 IOS 5.1 上，我在故事板上的视图控制器中添加了一个容器视图。我想通过 连接该容器视图IBOutlet，以便在 IB 上轻松管理它。

我尝试使用常规UIView：

@property (nonatomic,weak) IBOutlet UIView *leftView; //connected this to container view on interface builder

那么，如果我使用它，它就不起作用

[self.leftView addSubview:tableVC.view];

如果我以编程方式添加一个 childview 控制器，它可以工作，但它当然会覆盖全屏。

- (void)viewDidLoad
{
    [super viewDidLoad];
    // Do any additional setup after loading the view.
    UIStoryboard*  sb = [UIStoryboard storyboardWithName:@"MainStoryboard"
                                                  bundle:nil];
    UITableViewController *tableVC = [sb instantiateViewControllerWithIdentifier:@"LogMasterViewController"];
    [self.view addSubview:tableVC.view];

    [self addChildViewController:tableVC];
    [tableVC didMoveToParentViewController:self];
}

如何将容器视图连接到子视图控制器？

我刚刚测试了以下，它工作正常：

- (void)viewDidLoad
{
    [super viewDidLoad];

    UIStoryboard*  sb = [UIStoryboard storyboardWithName:@"MainStoryboard"
                                                  bundle:nil];
    UITableViewController *tableVC = [sb instantiateViewControllerWithIdentifier:@"LogMasterViewController"];
    [self.leftView addSubview:tableVC.view];
    tableVC.view.frame = self.leftView.bounds;

    [self addChildViewController:tableVC];
    [tableVC didMoveToParentViewController:self];
}

几个想法：

  1. 如果您LogMasterViewController不是 a UITableViewController，而是带有 a 的视图控制器UITableView，您可能需要确保该 tableview 上没有自动布局或自动调整大小的约束，从而使其将 tableview 的大小调整为您无法再看到的东西。

  2. 您可能想要运行该应用程序，在应用程序完成显示屏幕后暂停它（我在其中放置了一个断点viewDidAppear......该点之后的任何内容也应该可以工作，但不要执行viewDidLoador viewWillAppear），LogMasterViewController然后self.leftView输入在调试器控制台中执行以下命令：

    po [[UIWindow keyWindow] recursiveDescription]

    您可能希望提供唯一标签编号leftView的主要视图，LogMasterViewController以便您可以更轻松地破译输出。无论如何，使用它recursiveDescription来确定表格视图是否已呈现，但只是以一种您看不到表格的方式，或者根本没有添加它。您还可以确认您的leftView（带有唯一tag编号，如果您给它的话）也在那里。

    (lldb) po [[UIWindow keyWindow] recursiveDescription]

    在这个例子中，我的根控制器的主视图 atag为“1”，leftViewatag为“2”，主视图的主视图LogMasterViewController为tag“3”。在这种情况下，这些显示为我输出的第二、第三和第四行（我还看到了UITableViewCells下面的列表）。
