- (void)application:(UIApplication *)application didRegisterForRemoteNotificationsWithDeviceToken:(NSData *)deviceToken { 
    NSString *token = [NSString stringWithFormat:@"%@", deviceToken];
    //获取终端设备标识，这个标识需要通过接口发送到服务器端，服务器端推送消息到APNS时需要知道终端的标识，APNS通过注册的终端标识找到终端设备。
    NSLog(@"My token is:%@", token);   
}  
- (void)application:(UIApplication *)application didFailToRegisterForRemoteNotificationsWithError:(NSError *)error {   
    NSString *error_str = [NSString stringWithFormat: @"%@", error];   
    NSLog(@"Failed to get token, error:%@", error_str);   
}

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
  //判断是否由远程消息通知触发应用程序启动
    if ([launchOptions objectForKey:UIApplicationLaunchOptionsRemoteNotificationKey]!=nil) {
        //获取应用程序消息通知标记数（即小红圈中的数字）
        int badge = [UIApplication sharedApplication].applicationIconBadgeNumber;
        if (badge>0) {
           //如果应用程序消息通知标记数（即小红圈中的数字）大于0，清除标记。
            badge--;
          //清除标记。清除小红圈中数字，小红圈中数字为0，小红圈才会消除。
            [UIApplication sharedApplication].applicationIconBadgeNumber = badge;
        }
    }
    //消息推送注册
    [[UIApplication sharedApplication] registerForRemoteNotificationTypes:UIRemoteNotificationTypeSound|UIRemoteNotificationTypeAlert|UIRemoteNotificationTypeBadge];
}
3、在项目AppDelegate.m中加入消息接收处理代理方法。
//处理收到的消息推送
- (void)application:(UIApplication *)application 
didReceiveRemoteNotification:(NSDictionary *)userInfo
{
    //在此处理接收到的消息。
    NSLog(@"Receive remote notification : %@",userInfo);
}

public static void main(String[] args) throws Exception 
{
        try
        {
            //从客户端获取的deviceToken，在此为了测试简单，写固定的一个测试设备标识。
           String deviceToken = "df779eda 73258894 5882ec78 3ac7b254 6ebc66fe fa295924 440d34ad 6505f8c4"
            System.out.println("Push Start deviceToken:" + deviceToken);
            //定义消息模式
            PayLoad payLoad = new PayLoad();
            payLoad.addAlert("this is test!");
            payLoad.addBadge(1);//消息推送标记数，小红圈中显示的数字。
            payLoad.addSound("default");
            //注册deviceToken
            PushNotificationManager pushManager = PushNotificationManager.getInstance();
            pushManager.addDevice("iPhone", deviceToken);
            //连接APNS
            String host = "gateway.sandbox.push.apple.com";
            //String host = "gateway.push.apple.com";
            int port = 2195;
            String certificatePath = "c:/PushTest.p12";//前面生成的用于JAVA后台连接APNS服务的*.p12文件位置
            String certificatePassword = "123456";//p12文件密码。
            pushManager.initializeConnection(host, port, certificatePath, certificatePassword, SSLConnectionHelper.KEYSTORE_TYPE_PKCS12);
            //发送推送
            Device client = pushManager.getDevice("iPhone");
            System.out.println("推送消息: " + client.getToken()+"\n"+payLoad.toString() +" ");
            pushManager.sendNotification(client, payLoad);
            //停止连接APNS
            pushManager.stopConnection();
            //删除deviceToken
            pushManager.removeDevice("iPhone");
            System.out.println("Push End");
        }
        catch (Exception ex)
        {
            ex.printStackTrace();
        }
}
}
