【问题描述】：

当应用程序在后台接收到远程推送通知时，应用程序进入 applicationDidBecomeActive。从那里，我如何从通知中访问数据的 NSDictionary？

【参考方案1】：

通知数据在application:didReceiveRemoteNotification: 中传送到您的应用程序。如果你想在applicationDidBecomeActive: 中处理它，你应该将它存储在application:didReceiveRemoteNotification: 并在applicationDidBecomeActive 中再次读取。

【讨论】：

很抱歉恢复这个，但是当你收到关于 application:didReceiveRemoteNotification 的通知并且你的应用程序在前台时会发生什么，这意味着 applicationDidBecomeActive 将不会被调用。

在application:didReceiveRemoteNotification: 中，您可以查询-[UIApplication applicationState] 以了解您的应用是否已经在前台。如果是，则立即处理通知。

【参考方案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> 
    

【参考方案3】：

我使用这段代码来管理推送：

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。

编码愉快。

【参考方案4】：

如果您的应用在收到并点击推送通知时处于background 状态，则应用将使用application:didFinishLaunchingWithOptions: 而不是application:didReceiveRemoteNotification: 调用。

可以从launchOptions 字典中的application:didFinishLaunchingWithOptions: 访问推送通知负载。

【讨论】：

This is not correct application:didFinishLaunchingWithOptions: 应用在后台时不调用，仅在应用启动时调用。你所说的完全相反，首先它会被称为 application:didReceiveRemoteNotification: 然后是 applicationDidBecomeActive:
