3D触控动作不起作用(迅捷3)

Question

所以，我已经把所有的事情都做好了。当按下短键动作时，我会在控制台中得到正确的打印。我从这里要去哪里？我搞不懂..。

这是我在中的代码

    var quicklaunch: Bool!
    var viewName: String?

   func application(application: UIApplication, performActionForShortcutItem shortcutItem: UIApplicationShortcutItem, completionHandler: (Bool) -> Void) {
    viewName = shortcutItem.type
    quicklaunch = true
    completionHandler(quicklaunch)
}

func applicationDidBecomeActive(application: UIApplication) {
    if quicklaunch == true {
        quicklaunch = false
        if viewName == "Messages" {
            let rootViewController = self.window?.rootViewController
            let popUpController = UIStoryboard(name: "Main", bundle: nil).instantiateViewController(withIdentifier: "FriendsVC")
            rootViewController?.present(popUpController, animated: true, completion: nil)
            print("Worked")
        }
    }  
}

func application(_ application: UIApplication, performActionFor shortcutItem: UIApplicationShortcutItem, completionHandler: @escaping (Bool) -> Void) {
    if quicklaunch == false {
        quicklaunch = true
        if viewName == "Messages" {
            let rootViewController = self.window?.rootViewController
            let popUpController = UIStoryboard(name: "Main", bundle: nil).instantiateViewController(withIdentifier: "FriendsVC")
            rootViewController?.present(popUpController, animated: true, completion: nil)
            print("Worked")
        }
    }

}

如何让它弹出到正确的视图控制器？

Answer 1

您可以获取rootViewController，然后以模式方式呈现所需的viewController (如果rootViewController是UINavigationController，则将其推到导航堆栈上)。与…有关的东西

let rootViewController = self.window?.rootViewController
let popUpController = UIStoryboard(name: "Main", bundle: nil).instantiateViewController(withIdentifier: "???") as! ???
rootViewController.present(popUpController, animated: true, completion: nil)

用相应的值替换???

编辑

在AppDelegate中创建一个名为quickLaunch的布尔变量和一个字符串变量viewName。然后更新以下两种方法

func application(application: UIApplication, performActionForShortcutItem shortcutItem: UIApplicationShortcutItem, completionHandler: (Bool) -> Void) {
    viewName = shortcutItem.type
    quickLaunch = true
    completionHandler(quickLaunch)
}

func applicationDidBecomeActive(application: UIApplication) {
    if quickLaunch == true {
        quickLaunch = false
        //PRESENT YOUR VIEW MODALLY HERE
    }  
}
