如何从AppDelegate打开特定的选项卡视图

Question

我的根视图是标签栏控制器,我想在收到特定通知时在特定选项卡上打开应用程序.如果我使用presentViewController,标签栏会消失.有没有具体的方法来做到这一点？

Answer 1

func application(application: UIApplication, didFinishLaunchingWithOptions launchOptions: [NSObject: AnyObject]?) -> Bool {
    let myTabBar = self.window.rootViewController as! UITabBarController // Getting Tab Bar
    myTabBar.selectedIndex = 2 //Selecting tab here
    return true
}
