是否使用APNs?

首先，APNs不是绝对可靠；它可以取代SMS, 但是在某些情况下也可能代价高昂。

I would like to receive Push Notifications on my iPhone (instead of using expensive SMS gateway services).

一、配置流程

CSR ，保存私钥，设置密码
在新建app IDs的时候就生成SSL certificate（貌似与一般的证书生成不同）
制作pem文件，方便Your Server使用。以下三合一

The CSR
The private key as a p12 file (PushChatKey.p12)
The SSL certificate, aps_developer_identity.cer

二、APNs交互流程

三、代码节选

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions{self.window.rootViewController = self.viewController;[self.window makeKeyAndVisible]; // Let the device know we want to receive push notifications[[UIApplication sharedApplication] registerForRemoteNotificationTypes:(UIRemoteNotificationTypeBadge | UIRemoteNotificationTypeSound | UIRemoteNotificationTypeAlert)];     return YES;}

- (void)application:(UIApplication*)application didRegisterForRemoteNotificationsWithDeviceToken:(NSData*)deviceToken{NSLog(@"My token is: %@", deviceToken);} - (void)application:(UIApplication*)application didFailToRegisterForRemoteNotificationsWithError:(NSError*)error{NSLog(@"Failed to get token, error: %@", error);}

如果收不到apn消息:

1.请检查网络是否正常；

2.应用程序目前是否在前台，如在前台请切换至后台。
