How do I get `UIScreen.main.scale` after iOS 16
问题
UIScreen.main.scale 将被弃用。以下是UIKit.UIScreen文档中的内容：
@available(iOS, introduced: 2.0, deprecated: 100000, message: "Use a UIScreen instance found through context instead: i.e, view.window.windowScene.screen")
open class var main: UIScreen { get } // 设备的内部屏幕
deprecated: 100000 表示将被弃用。
所以我的问题是，我应该如何替换这个方法？
在主要的应用程序中，可以使用以下方法，但在扩展应用程序中 UIApplication.shared 不可用。是否有解决此问题的解决方案？
@available(iOSApplicationExtension, unavailable)
extension UIWindow {
static var current: UIWindow? {
for scene in UIApplication.shared.connectedScenes {
guard let windowScene = scene as? UIWindowScene else { continue }
for window in windowScene.windows {
if window.isKeyWindow { return window }
}
}
return nil
}
}
@available(iOSApplicationExtension, unavailable)
extension UIScreen {
static var current: UIScreen? {
UIWindow.current?.screen
}
}
英文:
UIScreen.main.scale will deprecated.
here it the document in UIKit.UIScreen
@available(iOS, introduced: 2.0, deprecated: 100000, message: "Use a UIScreen instance found through context instead: i.e, view.window.windowScene.screen")
open class var main: UIScreen { get } // the device's internal screen
deprecated: 100000 means to be deprecated.
So my question is how do I replace this method?
use below method can work in main App, but UIApplication.shared doesn't available in extension app. Is there any solution to resolve this problem
@available(iOSApplicationExtension, unavailable)
extension UIWindow {
static var current: UIWindow? {
for scene in UIApplication.shared.connectedScenes {
guard let windowScene = scene as? UIWindowScene else { continue }
for window in windowScene.windows {
if window.isKeyWindow { return window }
}
}
return nil
}
}
@available(iOSApplicationExtension, unavailable)
extension UIScreen {
static var current: UIScreen? {
UIWindow.current?.screen
}
}

得分: 1
extension UIViewController {
func screen() -> UIScreen? {
var parent = self.parent
var lastParent = parent
while parent != nil {
lastParent = parent
parent = parent!.parent
}
return lastParent?.view.window?.windowScene?.screen
}
}
在以下位置使用此扩展：
func scene(_ scene: UIScene, willConnectTo session: UISceneSession, options connectionOptions: UIScene.ConnectionOptions) {
let screen = windowScene.screen
}
英文:
extension UIViewController {
func screen() -> UIScreen? {
var parent = self.parent
var lastParent = parent
while parent != nil {
lastParent = parent
parent = parent!.parent
}
return lastParent?.view.window?.windowScene?.screen
}
}
and use this extension in
func scene(_ scene: UIScene, willConnectTo session: UISceneSession, options connectionOptions: UIScene.ConnectionOptions) {
let screen = windowScene.screen
