ios - 如何将容器 View 连接到 childviewcontroller.view

Question

在 IOS 5.1 上，我在 Storyboard上的 View Controller 中添加了一个容器 View 。我想通过 IBOutlet 连接那个容器 View ，这样我就可以在 IB 上轻松地管理它。

我尝试使用常规的 UIView:

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

然后，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 subview Controller ，它会工作，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 View 连接到 subview Controller ？

Answer 1

我刚刚测试了以下内容，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. 如果您的 LogMasterViewController 不是 UITableViewController，而是带有 UITableView 的 View Controller ，您可能想要确保您对该 tableview 没有自动布局或自动调整大小的约束，这些约束会使其将 tableview 的大小调整为您再也看不到的东西。

2. 您可能想要运行该应用程序，在该应用程序完成显示屏幕后暂停它(我在 viewDidAppear 中放置了一个断点......该点之后的任何内容也应该有效，但不要在 self.leftView 中使用 LogMasterViewController 执行 viewDidLoad 或 viewWillAppear，然后键入以下命令在调试器控制台中:

   po [[UIWindow keyWindow] recursiveDescription]
   

   您可能希望为您的 leftView 和 LogMasterViewController 的主视图提供唯一的标记编号，以便您可以更轻松地破译输出。无论如何，使用此 recursiveDescription 来确定 TableView 是否已经呈现，但只是以一种让您看不到表的方式，或者它是否根本没有添加。您还可以确认您的 leftView(带有唯一的 tag 编号，如果您给了它的话)也在那里。

   (lldb) po [[UIWindow keyWindow] recursiveDescription]

   在这个例子中，我给了我的根 Controller 的主视图一个 tag 为“1”，leftView 有一个 tag 为“2”，LogMasterViewController 的主视图有一个 tag 为“3”。在这种情况下，它们显示为我输出的第二、第三和第四行(我还看到下面列出的我的 UITableViewCells)。
