未收到推送通知

Question

我在我的应用中实施推送通知，一切似乎都正常，但推送通知未收到我的设备。

从上面的URL发出通知时，我收到了响应;

“连接到APNS消息已成功发送”。

但之后，我的设备上没有通知。请告诉我如何解决这个问题。

在第一次检查出你载荷描述你的推送通知的性质意味着它是否应该短信或警报或应用程序图标徽章。所以我们需要在JSON的合适的设置。检查出来首先，

我得到了同样的错误，因为我正在写错误的设备令牌，请检查您的设备令牌@“< XXx XXXX xxx ..”“更改为@”XXX XXX ..“ 或仅按照步骤

在应用程序委托

在didlaunch

// Register for sound and alert push notifications. 
    [[UIApplication sharedApplication] registerForRemoteNotificationTypes: 
    (UIRemoteNotificationTypeSound | UIRemoteNotificationTypeAlert)]; 

    // Check if the app was launched in response to the user tapping on a 
    // push notification. If so, we add the new message to the data model. 
    if (launchOptions != nil) 
    { 
     NSDictionary* dictionary = [launchOptions objectForKey:UIApplicationLaunchOptionsRemoteNotificationKey]; 
     if (dictionary != nil) 
     { 
      NSLog(@"Launched from push notification: %@", dictionary); 
     // [self addMessageFromRemoteNotification:dictionary updateUI:NO]; 
     } 
    }

} 

- (void)setDeviceToken:(NSString*)token

} 

从上面的代码获得设备令牌。

检查以下

1. 您是否获得了推送令牌。如果是，请从推送令牌中删除空格，然后从中删除> <。

2. 检查设备是否被连接到设置互联网

3. 检查通知是启用（或横幅或弹出式） - >通知 - >您的应用程序 - >选择横幅或警报（弹出）。

很可能，任何这些都会成为问题。

一个简单的把戏： 我有同样的问题，双重检查一切，重新创建pem等，但不能让我的最后一个开发证书超时后，我重新创建它。应用程序工作数月之前。

最终什么帮助真的从电话中擦除并重新安装它。 似乎一些存储的数据有点损坏...

请记住，应用程序然后将注册一个新的令牌。
