Question

我检查了我在GitHub和教程中找到的关于该主题的所有内容，但找不到合适的解决方案。

当我在移动推送网关tut中读到时，我可以发送一个字符串或类似的内容：

{
      "aps" : {
        "alert": "If you are reading this, you should have just received an alert.",
        "badge": 9,
        "sound": "bingbong.aiff"
      }
}

所以我尝试将其作为NSString，NSDictionary和NSData发送，但我无法收到。

我尝试的解决方案：

a，

NSString *apns = [NSString stringWithFormat:@"hello world."];
[PubNub sendMessage: apns toChannel:channel_3];

b，

NSDictionary *dict = @{
                       @"aps" : @{ @"alert" : @"new push" }
                       };
[PubNub sendMessage: dict toChannel:channel_3];

c，

// create the apns dictionary
NSString *apns = [NSString stringWithFormat:@"hello world."];
NSDictionary *dict = @{ @"aps" : @{ @"alert" : apns } };


//create the json
NSError *error;
NSData *jsonData = [NSJSONSerialization dataWithJSONObject:dict
                                                   options:NSJSONWritingPrettyPrinted
                                                     error:&error];

 NSString* jsonString = [[NSString alloc] initWithData:jsonData encoding:NSUTF8StringEncoding];
 [PubNub sendMessage: jsonString toChannel:channel_3];

d，

NSString *apns = [NSString stringWithFormat:@"hello world."];
NSDictionary *dict = @{ @"aps" : @{ @"alert" : apns } };


//create the json
NSError *error;
NSData *jsonData = [NSJSONSerialization dataWithJSONObject:dict
                                                   options:NSJSONWritingPrettyPrinted
                                                     error:&error];


[PubNub sendMessage: jsonData toChannel:channel_3];

E，

NSDictionary *pushPub = [[NSDictionary alloc]init];
pushPub = @{ @"alert": someString} ;
NSMutableDictionary *fullPush = [NSMutableDictionary dictionary];
[fullPush setObject:pusPub forKey:@"aps"];
[PubNub sendMessage: jsonData toChannel:channel_3];

我没有更多的想法，我可以尝试除此之外的东西。否则我收到了欢迎信息，所以它已正确实施。

我正在两台iPhone上测试它，并在我的AppDelegate中使用此代码（与设置指南verison相同）。

// #5 Process received push notification
- (void)application:(UIApplication *)application didReceiveRemoteNotification:(NSDictionary *)userInfo
{

    NSLog(@"PUSH TEST LOG");
    NSString *message = nil;
    id alert = [userInfo objectForKey:@"aps"];
    if ([alert isKindOfClass:[NSString class]]) {
        message = alert;
    } else if ([alert isKindOfClass:[NSDictionary class]]) {
        message = [alert objectForKey:@"alert"];
    }
    if (alert) {
        UIAlertView *alertView = [[UIAlertView alloc] initWithTitle:message
                                                            message:message  delegate:self
                                                  cancelButtonTitle:@"Thanks PubNub!"
                                                  otherButtonTitles:@"Send Me More!", nil];
        [alertView show];
    }
}

我在ViewController的'viewDidLoad'

中使用此功能

 [[PNObservationCenter defaultCenter] addClientConnectionStateObserver:self withCallbackBlock:^(NSString *origin, BOOL connected, PNError *connectionError){

        if (connected)
        {
            NSLog(@"OBSERVER: Successful Connection!");

            // Subscribe on connect
            [PubNub subscribeOnChannels:channels];


            // #3 Define AppDelegate
            AppDelegate *appDelegate = (AppDelegate *)[[UIApplication sharedApplication] delegate];

            // #4 Pass the deviceToken from the Delegate
            deviceToken = appDelegate.dToken;

            // #5 Double check we've passed the token properly
            NSLog(@"Device token received: %@", deviceToken);

            // #6 If we have the device token, enable apns for our channel if it isn't already enabled.
            if (deviceToken) {

                // APNS enabled already?
                [PubNub requestPushNotificationEnabledChannelsForDevicePushToken:deviceToken
                                                     withCompletionHandlingBlock:^(NSArray *channels, PNError *error){
                                                         if (channels.count == 0 )
                                                         {
                                                             NSLog(@"BLOCK: requestPushNotificationEnabledChannelsForDevicePushToken: Channel: %@ , Error %@",channels,error);

                                                             // Enable APNS on this Channel with deviceToken
                                                             [PubNub enablePushNotificationsOnChannel:myPushChannel
                                                                                  withDevicePushToken:deviceToken
                                                                           andCompletionHandlingBlock:^(NSArray *channel, PNError *error){
                                                                               NSLog(@"BLOCK: enablePushNotificationsOnChannel: %@ , Error %@",channel,error);
                                                                           }];
                                                         }
                                                     }];
            }
        }
        else if (!connected || connectionError != nil )
        {
            NSLog(@"OBSERVER: Error %@, Connection Failed!", connectionError.localizedDescription);
        }

    }];

我在控制台OBSERVER: Error %@, Connection Failed!"中看到了这个日志，但我也在同一个会话PubNub client successfully subscribed on channels: desiredChannels中有这个，所以我认为客户端可以订阅接收推送消息的频道，问题在于我的消息。可能有人可以给我一个正确的例子，我怎么能在obj-c中做到这一点？

Answer 1

事实证明，其他问题导致我的问题，所以我的一个实现是正确的。

这是一个合适的字典，您可以通过PubNub作为推送消息发送。

NSDictionary *myPushMessage = @{ @"aps" : @{ @"alert" : @"Push notification content" } };

PNChannel *pushReceiver = [PNChannel channelWithName:recevierChannel shouldObservePresence:NO];

[PubNub sendMessage: myPushMessage toChannel:pushReceiver];

如果您关注移动推送网关tutorial，它必须完美运行。

适当格式化的APN消息
