- (void)applicationDidBecomeActive:(UIApplication *)application

3.程序進入後臺

- (void)applicationDidEnterBackground:(UIApplication *)application

4.程序失去焦點

- (void)applicationWillResignActive:(UIApplication *)application

5.程序從後臺回到前臺

- (void)applicationWillEnterForeground:(UIApplication *)application

6.程序內存警告，可能要終止程序

-(void)applicationDidReceiveMemoryWarning:(UIApplication *)application

7.程序即將退出

- (void)applicationWillTerminate:(UIApplication *)application

8.向蘋果服務器請求deviceToken

    UIRemoteNotificationType types =

    (UIRemoteNotificationTypeBadge

     |UIRemoteNotificationTypeSound

     |UIRemoteNotificationTypeAlert);

    

    //註冊消息推送

didRegisterForRemoteNotificationsWithDeviceToken:(NSData *)deviceToken

10.推送向蘋果服務器請求deviceToken失敗時回調

- (void)application:(UIApplication *)application

- (void)application:(UIApplication *)application
didReceiveRemoteNotification:(NSDictionary *)userInfo

12.接收到遠程通知消息時回調
- (void)application:(UIApplication *)application
didReceiveRemoteNotification:(NSDictionary *)userInfo
fetchCompletionHandler:
(void (^)(UIBackgroundFetchResult))completionHandler

13.接收到本地通知消息時回調
