iOS - 使用PubNub发送Apple推送通知

Question

我正在整合PubNub（一种允许设备相互发送消息的服务）到我的iOS应用程序中。

我已按照页面上的说明操作：http://www.pubnub.com/docs/ios-objective-c/mobile-gateway

我已在 AppDelegate.m ：

中注册推送通知

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

    if ([[[UIDevice currentDevice] systemVersion] floatValue] >= 8.0) {
        [[UIApplication sharedApplication] registerForRemoteNotifications];
        UIUserNotificationSettings *settings = [UIUserNotificationSettings settingsForTypes:(UIUserNotificationTypeBadge
                                                                                             |UIUserNotificationTypeSound
                                                                                             |UIUserNotificationTypeAlert) categories:nil];
        [[UIApplication sharedApplication] registerUserNotificationSettings:settings];
    }

    return YES;
}

-(void) application:(UIApplication *)application didRegisterForRemoteNotificationsWithDeviceToken:(NSData *)deviceToken {
    NSLog(@"Application registered for push notifications");
}

-(void) application:(UIApplication *)application didFailToRegisterForRemoteNotificationsWithError:(NSError *)error {
    NSLog(@"Device failed to register for push:");
}

-(void) application:(UIApplication *)application didReceiveRemoteNotification:(NSDictionary *)userInfo {
    NSLog(@"Received push");
}

我正在 ViewController ：

中发送通知

NSDictionary *push = @{@"pn_apns" :
                               @{@"aps" : @{
                                         @"alert" : @"notification"
                                         }
                                 }
                           };

[self.pubNub sendMessage:@"sample" applePushNotification:push toChannel:[PNChannel channelWithName:@"test channel"] compressed:NO withCompletionBlock:^(PNMessageState state, id data) {
        switch (state) {
            case PNMessageSending:
                NSLog(@"sending message");
                break;

            case PNMessageSendingError:
                NSLog(@"error sending message");
                break;

            case PNMessageSent:
                NSLog(@"message sent");
                break;

            default:
                break;
        }
    }];

我收到消息发送回调，但推送通知未传递到第二个设备。
