- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions{

returnYES;

}//程式啟動進入執行的操作--初始化SDK,確定根視圖操作等

- (void)applicationWillResignActive:(UIApplication *)application{

}//應用失去焦點執行的操作

- (void)applicationDidEnterBackground:(UIApplication *)application{

}//應用程式進入後台執行的操作----記錄後台所處的頁面

- (void)applicationDidEnterBackground:(UIApplication *)application{

}//程式進入前台執行的操作----記錄頁面驗證手勢密碼和指紋密碼在應用視窗彈出，消失處理等問題

- (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.

}//程式已經處於焦點執行的操作

- (void)applicationWillTerminate:(UIApplication *)application {

    // Called when the application is about to terminate. Save data if appropriate. See also applicationDidEnterBackground:.

}//程式被終止進行的操作

 這個可以類比視圖的生命週期進行，在確定的時間段進行處理  從視圖啟動到視圖銷毀過程對比理解，執行相應的操作。
