无法让推送通知正常工作

Question

我正在尝试在我的应用程序中实现推送通知。我正在使用 APNs 身份验证密钥。到目前为止，我发现的每个指南都包含已弃用的方法或在 Swift 中。我对 this one 这样的指南感兴趣，但对 Objective C.

感兴趣

到目前为止我在 AppDelegate.m 里面做了什么：

@import Firebase;

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

    [FIRApp configure];

    NSDictionary *userInfo = [launchOptions objectForKey:UIApplicationLaunchOptionsRemoteNotificationKey];
    if (userInfo) {
        [self application:application didReceiveRemoteNotification:userInfo];
    }

    UIUserNotificationType allNotificationTypes =
    (UIUserNotificationTypeSound | UIUserNotificationTypeAlert | UIUserNotificationTypeBadge);
    UIUserNotificationSettings *settings =
    [UIUserNotificationSettings settingsForTypes:allNotificationTypes categories:nil];
    [[UIApplication sharedApplication] registerUserNotificationSettings:settings];
    [[UIApplication sharedApplication] registerForRemoteNotifications];

    return YES;
}


- (void)application:(UIApplication *)application
didReceiveRemoteNotification:(NSDictionary *)userInfo {



    // Perform different operations depending on the scenario
    if (application.applicationState == UIApplicationStateInactive) {

        // Opening the app
        NSLog(@"Firebase opening app");


    }
    else if (application.applicationState == UIApplicationStateBackground) {

        // Coming from background
        NSLog(@"Firebase background");

    }
    else {

        // Active
        NSLog(@"Firebase active");
    }

}

不幸的是，当我从 firebase 发送消息时，我什么也没收到，xcode 控制台中没有输出，也没有通知。如果您能指出正确的方向，我将不胜感激。

Answer 1

请使用此方法：

-(void)application:(UIApplication *)application didReceiveRemoteNotification:(NSDictionary *)userInfo fetchCompletionHandler:(void (^)(UIBackgroundFetchResult))completionHandler {
//Do something
}

而不是这个：

-(void)application:(UIApplication *)application didReceiveRemoteNotification:(NSDictionary *)userInfo {
 //Do something
}

更新：

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

    [FIRApp configure];

    UIUserNotificationType allNotificationTypes =
    (UIUserNotificationTypeSound | UIUserNotificationTypeAlert | UIUserNotificationTypeBadge);
    UIUserNotificationSettings *settings =
    [UIUserNotificationSettings settingsForTypes:allNotificationTypes categories:nil];
    [[UIApplication sharedApplication] registerUserNotificationSettings:settings];
    [[UIApplication sharedApplication] registerForRemoteNotifications];

 if ([application respondsToSelector:@selector(registerUserNotificationSettings:)])
      {
        #ifdef __IPHONE_8_0
        UIUserNotificationSettings *settings = [UIUserNotificationSettings settingsForTypes:(UIUserNotificationTypeAlert
                                                                                             | UIUserNotificationTypeBadge
                                                                                             | UIUserNotificationTypeSound) categories:nil];
        [application registerUserNotificationSettings:settings];
        #endif
       }
    else
      {
        UIRemoteNotificationType myTypes = UIRemoteNotificationTypeBadge | UIRemoteNotificationTypeAlert | UIRemoteNotificationTypeSound;
        [application registerForRemoteNotificationTypes:myTypes];
      }
    return YES;
}




-(void)application:(UIApplication *)application didRegisterForRemoteNotificationsWithDeviceToken:(NSData *)deviceToken
{

    [[FIRInstanceID instanceID] setAPNSToken:deviceToken type:FIRInstanceIDAPNSTokenTypeSandbox];
}

您没有实现 firebase apn 令牌，也没有连接到数据库。为什么不像这里 firebase example 那样实现它。你甚至设置了 plist 和 POD 库吗？在上面的代码示例中，版本 8/9 的 iOS 部分只有弃用的代码 - 意味着您可以忽略这些代码行。
