ios - 如果应用程序处于非事件状态，则访问推送负载

Question

我有一个推送通知，当应用收到它时，我调用以下方法

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

    if userInfo["t"] as! String == "rqst"  {

        print("type is help request")

        if let token = NSUserDefaults.standardUserDefaults().objectForKey("authToken") {
            authTokenOfHelper = token as! String
        }

        let storyBoard = UIStoryboard.init(name: "Main", bundle: nil)
        let viewController = storyBoard.instantiateViewControllerWithIdentifier("helperMap")
        let navController = UINavigationController.init(rootViewController: viewController)
        self.window?.rootViewController = nil
        self.window?.rootViewController = navController
        self.window?.makeKeyAndVisible()

        helpRequestReceived = true

    }

}

这会初始化 Storyboard。但是如果我的应用程序被系统杀死并且它已关闭并且设备收到推送，则在点击推送后什么也不会发生。

似乎我必须使用 application(application: UIApplication, didFinishLaunchingWithOptions launchOptions: [NSObject: AnyObject]?) 如果应用程序关闭

但是如何访问 didFinishLaunchingWithOptions 中的 userInfo 呢？

Answer 1

您可以使用 UIApplicationLaunchOptionsRemoteNotificationKey 作为启动选项在 didFinishLaunching 中进行检查。

UIApplicationLaunchOptionsRemoteNotificationKey: Indicates that a remote notification is available for the app to process. The value of this key is an NSDictionary containing the payload of the remote notification. > - alert: Either a string for the alert message or a dictionary with two keys: body and show-view. > - badge: A number indicating the quantity of data items to download from the provider. This number is to be displayed on the app icon. The absence of a badge property indicates that any number currently badging the icon should be removed. > - sound: The name of a sound file in the app bundle to play as an alert sound. If “default” is specified, the default sound should be played.

您可以在 application:didFinishLaunchingWithOptions: 中手动调用 application:didReceiveRemoteNotification:。

objective-c

- (BOOL)application:(UIApplication *)application
didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
    // ...

    if (launchOptions[UIApplicationLaunchOptionsRemoteNotificationKey]) {
        [self application:application didReceiveRemoteNotification:launchOptions[UIApplicationLaunchOptionsRemoteNotificationKey]];
    }

   return YES;
}

swift

func application(application: UIApplication, didFinishLaunchingWithOptions launchOptions: [NSObject: AnyObject]?) -> Bool {
        // Override point for customization after application launch.

        if let remoteNotification = launchOptions?[UIApplicationLaunchOptionsRemoteNotificationKey] as? NSDictionary {

            self.application(application, didReceiveRemoteNotification: launchOptions![UIApplicationLaunchOptionsRemoteNotificationKey]! as! [NSObject : AnyObject])

        }


        return true
    }
