objective-c - 两个 UISplitViewController，1 个(共享)详细 View

Question

设置场景我有:

• 带有 2 个选项卡的选项卡 View Controller
• 每个选项卡都有一个 Split View Controller
• 我想将每个 Split View Controller 的 Detail view 指向相同的 View 。

我附上了一个非常简单的 sample project showing the issue .

在 iPad 5.1 Sim 中运行它，观察每个选项卡。一个显示共享详细信息 View ，一个失败。

NSLog 调试报告第二个 Split View有一个 NULL 详细 View Controller :

2012-04-28 07:21:55.451 svcTest[14597:f803] tabBarController viewControllers = (    "UISplitViewController: 0x6a36100",    "UISplitViewController: 0x6a39ab0")2012-04-28 07:21:55.455 svcTest[14597:f803] svcA.viewControllers = (    "UINavigationController: 0x6a36250",    "UIViewController: 0x6a38720")2012-04-28 07:21:55.457 svcTest[14597:f803] svcB.viewControllers = (    "UINavigationController: 0x6a39cc0")

当您单击第二个选项卡时，出现此错误:

2012-04-28 07:22:58.457 svcTest[14597:f803] Splitview controller  is expected to have a detail children before its used!2012-04-28 07:22:58.459 svcTest[14597:f803] Split view controller  should have its children set before layout!

看 Storyboard，我已经设置了细节 View ，所以这让我很困惑。

非常感谢任何帮助让这个“共享” View 显示在每个选项卡上的帮助。

谢谢!

当为 splitViewController 指定两个以上的 viewController 时，我收到了相同的警告，如下所示:

self.splitViewController.viewControllers = @[masterNavigationController, detailNavigationController, subViewController];

当我从数组中删除“subViewController”时，警告消失了。

阅读苹果关于添加/删除 subview 的文档后，它提到了以下内容:

The array in this property must contain exactly two view controllers. The view controllers are presented left-to-right in the split view interface when it is in a landscape orientation. Thus, the view controller at index 0 is displayed on the left side and the view controller at index 1 is displayed on the right side of the interface.
