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：//每次唤醒- (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 = AnalyticsJSONTypeV
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.
