如何在swift中嵌入带有拆分视图控制器的标签栏控制器？

Question

我猜测应用代理需要进行更改吗？谢谢你的帮助！

Answer 1

1）通过xcode创建样本Master / Detail

2）在故事板上拖动TabBarController

3）将TabBarController更改为初始视图控制器。

4）控制从TabBarController拖动到SplitViewController

5）为故事板中的SplitViewController分配标题

6）在app delegate中，将SplitViewController的引用替换为如下。

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
