- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
說明：當應用程序啟動時執行，應用程序啟動入口。只在應用程序啟動時執行一次。
application參數用來獲取應用程序的狀態、變量等，值得注意的是字典參數：(NSDictionary *)launchOptions，該參數存儲程序啟動的原因。
若用戶直接啟動，lauchOptions內無數據;
若由其他應用程序通過openURL:啟動，則UIApplicationLaunchOptionsURLKey對應的對象為啟動URL（NSURL）,UIApplicationLaunchOptionsSourceApplicationKey對應啟動的源應用程序的bundle ID (NSString)；
若由本地通知啟動，則UIApplicationLaunchOptionsLocalNotificationKey對應的是為啟動應用程序的的本地通知對象(UILocalNotification)；
若由遠程通知啟動，則UIApplicationLaunchOptionsRemoteNotificationKey對應的是啟動應用程序的的遠程通知信息userInfo（NSDictionary）；
其他key還有UIApplicationLaunchOptionsAnnotationKey,UIApplicationLaunchOptionsLocationKey,
UIApplicationLaunchOptionsNewsstandDownloadsKey。 如果要在啟動時，做出一些區分，那就需要在下面的代碼做處理。 比如：應用可以被某個其它應用調起（作為該應用的子應用），要實現單點登錄，那就需要在啟動代碼的地方做出合理的驗證，并跳過登錄。
