- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
說明：當應(yīng)用程序啟動時執(zhí)行收恢，應(yīng)用程序啟動入口。只在應(yīng)用程序啟動時執(zhí)行一次。
application參數(shù)用來獲取應(yīng)用程序的狀態(tài)范舀、變量等，值得注意的是字典參數(shù)：(NSDictionary *)launchOptions了罪，該參數(shù)存儲程序啟動的原因锭环。
若用戶直接啟動，lauchOptions內(nèi)無數(shù)據(jù);
若由其他應(yīng)用程序通過openURL:啟動泊藕，則UIApplicationLaunchOptionsURLKey對應(yīng)的對象為啟動URL（NSURL）,UIApplicationLaunchOptionsSourceApplicationKey對應(yīng)啟動的源應(yīng)用程序的bundle ID (NSString)辅辩；
若由本地通知啟動，則UIApplicationLaunchOptionsLocalNotificationKey對應(yīng)的是為啟動應(yīng)用程序的的本地通知對象(UILocalNotification)；
若由遠程通知啟動玫锋，則UIApplicationLaunchOptionsRemoteNotificationKey對應(yīng)的是啟動應(yīng)用程序的的遠程通知信息userInfo（NSDictionary）蛾茉；
其他key還有UIApplicationLaunchOptionsAnnotationKey,UIApplicationLaunchOptionsLocationKey,
UIApplicationLaunchOptionsNewsstandDownloadsKey。 如果要在啟動時景醇，做出一些區(qū)分臀稚，那就需要在下面的代碼做處理。 比如：應(yīng)用可以被某個其它應(yīng)用調(diào)起（作為該應(yīng)用的子應(yīng)用）三痰，要實現(xiàn)單點登錄吧寺，那就需要在啟動代碼的地方做出合理的驗證，并跳過登錄散劫。
