推送通知的过程可以分为以下几步：  
    1.    应用服务提供商从服务器端把要发送的消息和设备令牌（device token）发送给苹果的消息推送服务器APNs。  
    2.    APNs根据设备令牌在已注册的设备（iPhone、iPad、iTouch、mac等）查找对应的设备，将消息发送给相应的设备。  
    3.    客户端设备接将接收到的消息传递给相应的应用程序，应用程序根据用户设置弹出通知消息。

\- (BOOL)application:(UIApplication \*)application didFinishLaunchingWithOptions:(NSDictionary \*)launchOptions \{  
    // Override point for customization after application launch.  
    //想APNS（苹果推送服务器）注册远程推送通知，APNS返回device token  
    float version = \[\[\[UIDevice currentDevice\] systemVersion\] floatValue\];  
    if (version >= 8.0) \{  
        \[\[UIApplication sharedApplication\] registerUserNotificationSettings:\[UIUserNotificationSettings settingsForTypes:UIUserNotificationTypeAlert|UIUserNotificationTypeSound|UIUserNotificationTypeBadge categories:nil\]\];  
          
        //注册远程推送通知  
        \[\[UIApplication sharedApplication\] registerForRemoteNotifications\];  
    \}else\{  
        //ios8以下  
        \[\[UIApplication sharedApplication\] registerForRemoteNotificationTypes:UIRemoteNotificationTypeAlert|UIRemoteNotificationTypeSound|UIRemoteNotificationTypeBadge\];  
    \}  
      
    return YES;  
\}  
  
//当向APNS注册成功时的回调函数  
\-(void)application:(UIApplication \*)application didRegisterForRemoteNotificationsWithDeviceToken:(NSData \*)deviceToken  
\{  
    NSLog(@"%@",deviceToken);  
    //需要把deviceToken上传到服务端，要服务端提供接口  
\}  
  
\-(void)application:(UIApplication \*)application didFailToRegisterForRemoteNotificationsWithError:(NSError \*)error\{  
    NSLog(@"%@",error.localizedDescription);  
\}  
  
\-(void)application:(UIApplication \*)application didReceiveRemoteNotification:(NSDictionary \*)userInfo  
\{  
    NSLog(@"收到了远程推送通知");  
\}
