ios推送

原文地址：blog.csdn.net/ios_che/article/details/7428413

推送通知的步骤：1、询问是否允许推送通知。2、如果用户允许在APPDELEGATE 中实现

- (void)application:(UIApplication *)application didRegisterForRemoteNotificationsWithDeviceToken:(NSData *)deviceToken{

}

3、将token发送到服务器上

4、服务器收到toke后 发送推送通知，客户端相应该推送同通知

代码如下：

- (void)applicationDidBecomeActive:(UIApplication *)application{    /*     Restart any tasks that were paused (or not yet started) while the application was inactive. If the application was previously in the background, optionally refresh the user interface.     */        //每次醒来都需要去判断是否得到device token    [NSTimer scheduledTimerWithTimeInterval:0.5 target:self selector:@selector(registerForRemoteNotificationToGetToken) userInfo:nil repeats:NO];    //hide the badge    application.applicationIconBadgeNumber = 0;    [[CheckVersion sharedCVInstance] checkVersionOfServer];        [[AnalyticsUtil sharedAnalyticsUtil] appLaunch];        AnalyticsJSONElement *viewElement = [[AnalyticsJSONElement alloc] init];    viewElement.jsonType = AnalyticsJSONTypeView;    viewElement.typeID = @"0";    [[AnalyticsUtil sharedAnalyticsUtil] postAnalyticsMsgToServerWithElement:viewElement];    [viewElement release];    }- (void)applicationWillTerminate:(UIApplication *)application{    /*     Called when the application is about to terminate.     Save data if appropriate.
