- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
说明：当应用程序启动时执行，应用程序启动入口。只在应用程序启动时执行一次。
application参数用来获取应用程序的状态、变量等，值得注意的是字典参数：(NSDictionary *)launchOptions，该参数存储程序启动的原因。
若用户直接启动，lauchOptions内无数据;
若由其他应用程序通过openURL:启动，则UIApplicationLaunchOptionsURLKey对应的对象为启动URL（NSURL）,UIApplicationLaunchOptionsSourceApplicationKey对应启动的源应用程序的bundle ID (NSString)；
若由本地通知启动，则UIApplicationLaunchOptionsLocalNotificationKey对应的是为启动应用程序的的本地通知对象(UILocalNotification)；
若由远程通知启动，则UIApplicationLaunchOptionsRemoteNotificationKey对应的是启动应用程序的的远程通知信息userInfo（NSDictionary）；
其他key还有UIApplicationLaunchOptionsAnnotationKey,UIApplicationLaunchOptionsLocationKey,
UIApplicationLaunchOptionsNewsstandDownloadsKey。 如果要在启动时，做出一些区分，那就需要在下面的代码做处理。 比如：应用可以被某个其它应用调起（作为该应用的子应用），要实现单点登录，那就需要在启动代码的地方做出合理的验证，并跳过登录。
