Question

当应用程序在后台时收到远程推送通知时，应用程序会输入applicationDidBecomeActive。从那里，我如何从通知中访问数据的NSDictionary？

Answer 1

通知数据会在application:didReceiveRemoteNotification:中传送到您的应用。如果您要在applicationDidBecomeActive:中处理它，则应将其存储在application:didReceiveRemoteNotification:中，然后在applicationDidBecomeActive中再次阅读。

Answer 2

Swift版本：

var dUserInfo: [NSObject : AnyObject]?

func application(application: UIApplication, didFinishLaunchingWithOptions launchOptions: [NSObject: AnyObject]?) -> Bool {

// code...

if let info = launchOptions?[UIApplicationLaunchOptionsRemoteNotificationKey] as? [NSObject : AnyObject] {
        dUserInfo = info
    }

    return true
}

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

func applicationDidBecomeActive(application: UIApplication) {
    // code...

    self.yourAction(dUserInfo)
}

func yourAction(userInfo: [NSObject : AnyObject]?) {
    if let info = userInfo?["aps"] as? Dictionary<String, AnyObject> {
    }
}

Answer 3

我使用此代码来管理推送：

在AppDelegate

中

@implementation AppDelegate{
    NSDictionary *dUserInfo; //To storage the push data
}

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
    //Check for options
    if (launchOptions != nil)
    {
        //Store the data from the push.
        dUserInfo = [launchOptions objectForKey:UIApplicationLaunchOptionsRemoteNotificationKey];
        if (dUserInfo != nil)
        {
            //Do whatever you need
        }
    }

    return YES;
}

- (void)applicationDidBecomeActive:(UIApplication *)application
{   
    //Data from the push.
    if (dUserInfo != nil)
    {
        //Do whatever you need
    }
}

- (void)application:(UIApplication *)application didReceiveRemoteNotification:(NSDictionary *)userInfo
{
    //Store the data from the push.
    if (userInfo != nil)
    {
        dUserInfo = userInfo;
    }
}

我希望这对某人有用。

快乐的编码。

如果您的应用处于background状态时收到推送通知并点按，则会使用application:didFinishLaunchingWithOptions:而不是application:didReceiveRemoteNotification:来调用该应用。

推送通知有效负载可以在application:didFinishLaunchingWithOptions:字典launchOptions中访问。

如何在applicationDidBecomeActive上访问远程推送通知数据？
