在iOS中解析moengage通知响应中的问题？

Question

我在解析Moengage通知响应时遇到了一个问题，如下所示

发自：

   -(void)application:(UIApplication *)application didReceiveRemoteNotification:(NSDictionary *)userInfo fetchCompletionHandler:(void (^)(UIBackgroundFetchResult result))handler
{
  NSLog(@"notification appdelegate  %@",userInfo);
  [self customPushHandler:userInfo];

}

notification app delegate: { "app_extra" = { screenData = { "" = ""; }; screenName = ""; }; aps = { alert = "iOS Test "; badge = 1; "content-available" = 0; sound = default; }; moengage = { "" = ""; cid = ; }; }

- (void) customPushHandler:(NSDictionary *)notification {

 if (notification !=nil && [notification objectForKey:@"app_extra"] != nil) {
    NSDictionary* app_extra_dict = [notification objectForKey:@"app_extra"];

      NSDictionary* app_extra_dict1 = [[notification objectForKey:@"app_extra"]objectForKey:@"aps"];

      NSDictionary* app_extra_dict2 = [[notification objectForKey:@"aps"];

      NSLog(@"Moenage notification %@",notification);
      NSLog(@"Menage   apps  %@",app_extra_dict1);
      NSLog(@"Moenage apps %@",app_extra_dict2);               
      NSLog(@"Moenage %@",app_extra_dict );

   }
  }

日志：

above通知:与上述答复相同 菜单应用程序(null) Moenage应用程序(空) Moenage：

{ screenData = { "" = ""; }; screenName = ""; }

现在我的问题是我正在尝试检索“aps ={iOS=”JSON..can ";“..But --不是JSON..can--请建议我解析这个响应，或者是他们从这个响应中检索"iOS测试”的方法。

通过将上面的响应转换为Jsonstring和than NSDictionary解决了这个问题：

   - (void) customPushHandler:(NSDictionary *)notification {

 if (notification !=nil && [notification objectForKey:@"app_extra"] != nil) {

    NSError *error;
    NSData *jsonData = [NSJSONSerialization dataWithJSONObject:notification
                                                       options:NSJSONWritingPrettyPrinted // Pass 0 if you don't care about the readability of the generated string
                                                         error:&error];

    if (! jsonData) {
        NSLog(@"Got an error: %@", error);
    } else {
        NSString *jsonString = [[NSString alloc] initWithData:jsonData encoding:NSUTF8StringEncoding];

        NSLog(@"Got jsonString: %@", jsonString);

        NSError *jsonError;
        NSData *objectData = [jsonString dataUsingEncoding:NSUTF8StringEncoding];
        NSDictionary *json = [NSJSONSerialization JSONObjectWithData:objectData
                                                             options:NSJSONReadingMutableContainers
                                                               error:&jsonError];


         NSLog(@"json %@",json[@"aps"][@"alert"]);


    }

}

获取数据的格式没有什么问题，也不需要转换为JSON，您已经在NSDictionary中获取数据了。您的答案是将字典转换为JSON，然后再次转换JSON以获得相同的字典，这是没有任何意义的。只需使用以下键即可访问所有值：

- (void) customPushHandler:(NSDictionary *)notification {

if (notification !=nil && [notification objectForKey:@"app_extra"] != nil) {

    NSDictionary* app_extra_dict = [notification objectForKey:@"app_extra"];
    NSDictionary* aps_dict = [notification objectForKey:@"aps"];

    NSLog(@"Moengage notification : %@",notification);
    NSLog(@"Moengage   appsExtra : %@",app_extra_dict);
    NSLog(@"Moengage aps : %@",aps_dict);
}
}

下面是相同的原木：

    Moengage notification :  {
    "app_extra" =     {
        screenData =         {
            key1 = Val1;
        };
        screenName = Screen1;
    };
    aps =     {
        alert = "Hello!!!";
        badge = 1;
        "content-available" = 0;
        sound = default;
    };
    moengage =     {
        cid = 5715f243597b7b0f37a9254a;
        key1 = Val1;
    };
}

 Moengage   appsExtra :  {
    screenData =     {
        key1 = Val1;
    };
    screenName = Screen1;
}

Moengage aps :  {
    alert = "Hello!!!";
    badge = 1;
    "content-available" = 0;
    sound = default;
}

试着像这样打印：

- (void) customPushHandler:(NSDictionary *)notification {
    NSLog(@"notification:%@", notification);
    NSLog(@"Moenage:%@", notification[@"app_extra"]);
    NSLog(@"Menage apps:%@", notification[@"aps"]);
}
