ios - 尽管我收到通知，但 Didreceivenotification 从未被调用

Question

(void)application:(UIApplication *)application
     didReceiveRemoteNotification:(NSDictionary *)userInfo ;

和

 - (void)application:(UIApplication *)application didReceiveRemoteNotification:
                    (NSDictionary *)userInfo fetchCompletionHandler:(void (^)(UIBackgroundFetchResult 
                     result))completionHandler{};

从来没有接到电话，虽然我在 iphone 上收到通知，是否需要添加任何其他功能才能正常工作？谢谢。

更新当应用程序不在后台也不处于事件状态但我没有收到消息时，我尝试了此操作。 - (BOOL)应用程序:(UIApplication *)应用程序didFinishLaunchingWithOptions:(NSDictionary *)launchOptions { //为 |GPPSignIn| 设置应用程序的客户端 ID和 |GPPShare|。

[[UIApplication sharedApplication]
 registerForRemoteNotificationTypes:(UIRemoteNotificationTypeAlert | UIRemoteNotificationTypeBadge | UIRemoteNotificationTypeSound)];

// Clear application badge when app launches
application.applicationIconBadgeNumber = 0;
if ([[launchOptions allKeys] containsObject:UIApplicationLaunchOptionsRemoteNotificationKey]) {

    id userInfo=[launchOptions objectForKey:UIApplicationLaunchOptionsRemoteNotificationKey];
    UIAlertView * alert = [[UIAlertView alloc]initWithTitle:@"MESSAGE" message:userInfo delegate:self cancelButtonTitle:@"ok" otherButtonTitles: nil];
    [alert show];
}

Answer 1

如果您的应用程序关闭并收到通知......

在didFinishLaunchingWithOptions中添加以下代码

if ([[launchOptions allKeys] containsObject:UIApplicationLaunchOptionsRemoteNotificationKey]) 
{    
    id userInfo=[launchOptions objectForKey:UIApplicationLaunchOptionsRemoteNotificationKey];
    NSLog(@"%@",[[userInfo objectForKey:@"aps"] objectForKey:@"alert"]);
    UIAlertView * alert = [[UIAlertView alloc]initWithTitle:@"MESSAGE" message:[[userInfo objectForKey:@"aps"] objectForKey:@"alert"] delegate:self cancelButtonTitle:@"ok" otherButtonTitles: nil];
    [alert show];
}

但是当你点击通知时这个调用
