ios - 如何在 swift 中嵌入带有 Split View Controller 的选项卡栏 Controller ？

Question

我猜 app delegate 需要改变吗？感谢您的帮助!

Answer 1

1) 通过 xcode 创建一个示例 Master/Detail

2) 在 Storyboard上拖一个TabBarController

3) 将 TabBarController 更改为初始 View Controller 。

4) 控件从TabBarController拖到SplitViewController

5) 为 Storyboard中的SplitViewController 分配标题

6) 在应用委托(delegate)中替换对 SplitViewController 的引用，如下所示。

let tabBarViewController = self.window!.rootViewController as! UITabBarController
print(tabBarViewController.viewControllers?.count)
var splitViewController:UISplitViewController? = nil
for viewController in tabBarViewController.viewControllers! {
if viewController.title == "Master" {
    splitViewController = viewController as? UISplitViewController
}
}

let navigationController = splitViewController!.viewControllers[splitViewController!.viewControllers.count-1] as! UINavigationController
navigationController.topViewController!.navigationItem.leftBarButtonItem = splitViewController!.displayModeButtonItem()
splitViewController!.delegate = self
