我正在学习如何在没有Interface Builder(即故事板,xib等)的情况下创建iOS应用程序.下面是我正在使用的基本应用程序委托类.问题是,当显示时,UIWindow不会用完设备的全屏(参见附件截图).这发生在我测试的所有设备和模拟器上.为什么不使用全屏？
import UIKit
@UIApplicationMain
class AppDelegate: UIResponder,UIApplicationDelegate {
lazy var window: UIWindow? = {
debugPrint("AppDelegate: Creating Window")
let screen: UIScreen = UIScreen.mainScreen()
let window: UIWindow = UIWindow.init(frame: screen.bounds)
window.backgroundColor = UIColor.whiteColor()
return window
}()
lazy var rootViewController: ShapesViewController = {
debugPrint("AppDelegate: Creating Root View Controller")
let rootViewController = ShapesViewController.init(nibName: nil,bundle: nil)
return rootViewController
}()
func application(application: UIApplication,didFinishLaunchingWithOptions launchOptions: [NSObject : AnyObject]?) -> Bool {
debugPrint("AppDelegate: applicationWillEnterForeground")
window?.rootViewController = rootViewController
window?.makeKeyAndVisible()
return true
}
}
解决方法
问题是我没有发布图像或故事板.由于某些原因没有这个,应用程序默认为3.5“大小.相信这个评论：
A launch storyboard or xib must be provided unless the app requires full screen
