iOS消息推送實現

客戶端

** 證書和權限的申請：***

•   1 ：App必須要推送權限，申請真機測試權限
  

•   2 ：對應的appID申請推送證書
  

•   3 ：使用推送證書到處P12證書給服務器使用
  

客戶端代碼實現：

• 1：建立我們的推送的項目（注意BundleIdentifier必須和我們推送應用的App id一致）

• 2：在AppDelegate里didFinishLaunchingWithOptions函數里寫

- (BOOL)application:(UIApplication *)applicationdidFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
   ……
   //推送的形式：標記，聲音，提示
   [[UIApplication sharedApplication] registerForRemoteNotificationTypes: UIRemoteNotificationTypeBadge |UIRemoteNotificationTypeSound | UIRemoteNotificationTypeAlert];
   return YES;
}

 
- (void)application:(UIApplication *)applicationdidRegisterForRemoteNotificationsWithDeviceToken:(NSData *)pToken {
   NSLog(@"regisger success:%@",pToken);
   //注冊成功，將deviceToken保存到應用服務器數據庫中
}
- (void)application:(UIApplication *)application didReceiveRemoteNotification:(NSDictionary *)userInfo{
    // 處理推送消息
    NSLog(@"userinfo:%@",userInfo);
   
    NSLog(@"收到推送消息:%@",[[userInfo objectForKey:@"aps"] objectForKey:@"alert"]);
}
- (void)application:(UIApplication *)applicationdidFailToRegisterForRemoteNotificationsWithError:(NSError *)error {
   NSLog(@"Registfail%@",error);
}

服務器端

服務端開發的思路都差不多，使用第三方封裝好的包，這個包如果自己寫還是很麻煩的。
這里以pushSharp 為例，一個開源的c#推送代碼

關鍵代碼說明：

var appleCert = File.ReadAllBytes(Path.Combine(AppDomain.CurrentDomain.BaseDirectory, "../../id4test_push_aps_development.p12"));//證書位置
            //IMPORTANT: If you are using a Development provisioning Profile, you must use the Sandbox push notification server 
            //  (so you would leave the first arg in the ctor of ApplePushChannelSettings as 'false')
            //  If you are using an AdHoc or AppStore provisioning profile, you must use the Production push notification server
            //  (so you would change the first arg in the ctor of ApplePushChannelSettings to 'true')
            push.RegisterAppleService(new ApplePushChannelSettings(appleCert, "WEIWEI")); //Extension method
            //Fluent construction of an iOS notification
            //IMPORTANT: For iOS you MUST MUST MUST use your own DeviceToken here that gets generated within your iOS app itself when the Application Delegate
            //  for registered for remote notifications is called, and the device token is passed back to you
            push.QueueNotification(new AppleNotification()
                                       .ForDeviceToken("cde6d75a0fc144b2bd30e10e15855376e4b53d793e6ccf9495787df19ace48d4")//手機設備token
                                       .WithAlert("Hello World!")
                                       .WithBadge(7)
                                       .WithSound("sound.caf"));
