Question

我希望在收到推送通知后导航到某个视图控制器。导航后，导航堆栈应该像用户手动进入视图一样工作。

故事板：http://www.xpos.nl/xpos/images/common/storyboard.png

在AppDelegate.swift中我已经有了：

func application(application: UIApplication, didReceiveRemoteNotification userInfo: [NSObject : AnyObject]) {

    println("didReceiveRemoteNotification")

    let storyboard = UIStoryboard(name: "Main", bundle: nil)

    let destinationViewController = storyboard.instantiateViewControllerWithIdentifier("MessageViewController") as MessageViewController

    let navigationController = self.window?.destinationViewController;

    navigationController?.pushViewController(destinationViewController, animated: false, completion: nil)

}

但是我得到一个错误，即destinationViewController不是窗口的一部分，或者如果我更正（在stackoverflow上尝试其他答案），没有任何反应。

Answer 1

destinationViewController不是窗口的一部分，因为它尚未添加，只是初始化。基于navigationViewController是你的rootViewController的假设，推送到你的destinationViewController，如下所示：

func application(application: UIApplication, didReceiveRemoteNotification userInfo: [NSObject : AnyObject]) {

    println("didReceiveRemoteNotification")

    let storyboard = UIStoryboard(name: "Main", bundle: nil)

    let destinationViewController = storyboard.instantiateViewControllerWithIdentifier("MessageViewController") as MessageViewController

    let navigationController = self.window?.rootViewController as! UINavigationController

    navigationController?.pushViewController(destinationViewController, animated: false, completion: nil)

}

此外：要从“Bestellen”推送到“MessageViewController”然后弹出到“Berichten”，您还需要在这两者之间推送所有其他viewControllers。没有内置的功能或算法来做到这一点。

试试这个

    func application(application: UIApplication, didReceiveRemoteNotification userInfo: [NSObject : AnyObject]) {

    println("didReceiveRemoteNotification")

    let storyboard = UIStoryboard(name: "Main", bundle: nil)

    let destinationViewController = storyboard.instantiateViewControllerWithIdentifier("MessageViewController") as MessageViewController

    self.window?.rootViewController?.presentViewController(destinationViewController, animated: True, completion:nil)

    }
