问题描述
随着 iOS 13 的到来，statusBar的视图不再可通过槽访问:
With the arrival of iOS 13 statusBar's view is no longer accessible trough:
value(forKey: "statusBar") as? UIView
由于:
但是由于keyWindow?.windowScene?.statusBarManager似乎不包含与之相关的任何内容，因此尚不清楚应如何使用它来更改颜色.
But it's not clear how it should be used for changing colours as keyWindow?.windowScene?.statusBarManager does not appear to contain anything related to it.
我正在编译具有(iOS 10，*)兼容性的代码，所以我打算继续使用UIKit.
关于这个主题有什么想法吗?
推荐答案
您可以添加一些条件或使用第一个条件.只需为UIApplication创建一些扩展即可.
You can add some conditions or use first one. Just create some extension for UIApplication.
extension UIApplication {
var statusBarUIView: UIView? {
if #available(iOS 13.0, *) {
let tag = 38482
let keyWindow = UIApplication.shared.windows.filter {$0.isKeyWindow}.first
if let statusBar = keyWindow?.viewWithTag(tag) {
return statusBar
} else {
guard let statusBarFrame = keyWindow?.windowScene?.statusBarManager?.statusBarFrame else { return nil }
let statusBarView = UIView(frame: statusBarFrame)
statusBarView.tag = tag
keyWindow?.addSubview(statusBarView)
return statusBarView
}
} else if responds(to: Selector(("statusBar"))) {
return value(forKey: "statusBar") as? UIView
} else {
return nil
}
}
}
更新:对不起，我没有足够的时间在实际项目中对其进行测试，但是它可以在"Hello world"应用程序中使用.您可以阅读有关 keyWindow 的更多信息，以及 statusBarFrame ，以使其更好.
UPDATED: Sorry, I don't have enough time to test it in real projects, but it works in "Hello world" app. You can read more info about keyWindow and statusBarFrame in order to make it better.
extension UIApplication {
var statusBarUIView: UIView? {
if #available(iOS 13.0, *) {
let tag = 3848245
let keyWindow = UIApplication.shared.connectedScenes
.map({$0 as? UIWindowScene})
.compactMap({$0})
.first?.windows.first
if let statusBar = keyWindow?.viewWithTag(tag) {
return statusBar
} else {
let height = keyWindow?.windowScene?.statusBarManager?.statusBarFrame ?? .zero
let statusBarView = UIView(frame: height)
statusBarView.tag = tag
statusBarView.layer.zPosition = 999999
keyWindow?.addSubview(statusBarView)
return statusBarView
}
} else {
if responds(to: Selector(("statusBar"))) {
return value(forKey: "statusBar") as? UIView
}
}
return nil
}
}
