ios – 当主视图控制器是UITabBarController时,自适应显示细节segue转换为模式而不是推送iPhone

>使用自定义UISplitViewController(子类)
>覆盖showDetailViewController操作
>使用traitCollection来确定UISplitViewController的类
>如果水平类是Compact,请获取navigationController来调用showViewController

以下是自定义UISplitViewController的代码：

import UIKit

class CustomSplitViewController: UISplitViewController {

    override func showDetailViewController(vc: UIViewController!,sender: AnyObject!) {

        if (self.traitCollection.horizontalSizeClass == UIUserInterfaceSizeClass.Compact) {
            if let tabBarController = self.viewControllers[0] as? UITabBarController {
                if let navigationController = tabBarController.selectedViewController as? UINavigationController {
                    navigationController.showViewController(vc,sender: sender)
                    return
                }
            }
        }

        super.showDetailViewController(vc,sender: sender)
    }
}

不要忘记在故事板中设置自定义类.

在iPhone 6,iPhone 6和iPad Air的模拟器中测试,并按预期工作.
