/*
//UIApplicationDelegate委托代理方法
1.程序开始:didFinishLaunchingWithOptions:程序开始
2.程序挂起:applicationWillResignActive
3.程序复原(程序重新激活):applicationDidBecomeActive
注意：应用程序在启动时，在调用了 applicationDidFinishLaunching 方法之后也会调用 applicationDidBecomeActive 方法，所以你要确保你的代码能够分清复原与启动，避免出现逻辑上的bug。
4.程序意外暂行(终止):applicationWillTerminate
5.程序进入后台:applicationDidEnterBackground
6.程序进入前台:applicationWillEnterForeground
//调用方法场景
首次运行：
didFinishLaunchingWithOptions//程序开始
applicationDidBecomeActive//程序复原(程序重新激活)
首次关闭（home）：
applicationWillResignActive//程序挂起
applicationDidEnterBackground//程序进入后台
再次运行：
applicationWillEnterForeground//程序进入前台
applicationDidBecomeActive//程序复原(程序重新激活)
再次关闭：
applicationWillResignActive//程序挂起
applicationDidEnterBackground//程序进入后台
