一周的學習即將結(jié)束，今天學習到了霓虹燈的做法靠瞎，感覺很happy,分享一下制作方法
//應運程序代理類
//AppDelegate中的方法都是UIApplicationDelegate中的協(xié)議方法
//UIApplication應運程序類
class AppDelegate: UIResponder, UIApplicationDelegate {
//應用程序窗口闯捎，是AppDelegate類的屬性
var window: UIWindow?
//應運程序加載完成的時候觸發(fā)這個方法
func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplicationLaunchOptionsKey: Any]?) -> Bool {
// Override point for customization after application launch.
//想再window對象添加內(nèi)容妖碉，就在這個方法中實現(xiàn)
//UIScreen屏幕類
//UIScreen.main獲取屏幕對象
//UIScreen.main.bounds獲取屏幕大小
self.window = UIWindow(frame: UIScreen.main.bounds)
self.window?.backgroundColor = #colorLiteral(red: 1, green: 1, blue: 1, alpha: 1)
//讓window成為應用程序的主窗口，并使其可見
self.window?.makeKeyAndVisible()
//給window設置根視圖控制器
self.window?.rootViewController = UIViewController()
