如何在推送通知时导航到查看控制器

pushviewcontroller push-notification swift ios

我想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访问视图一样工作。

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

在AppDelegate.swift中,我已经:

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)

}

但我得到了一个错误,即destinationViewController不是窗口的一部分,或者如果我纠正了这个错误(在stackoverflow上尝试其他答案),什么都不会发生。

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rootViewController的假设,按如下方式推送到destinationViewController:

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)

}

另外:要从“Bestellen”推送到“MessageViewController”,然后弹出到“Berichten”,还需要在这两个视图控制器之间推送所有其他视图控制器。没有内置的函数或算法可以做到这一点。

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)

    }
