The background color of the navigation bar of "Photo Library" displayed by WKWebView in iOS15 does not work with the backgroudColor of UINavigationBarAppearance().
It works on iOS14.
AppDelegate.swift
if #available(iOS 15, *) {
let appearance = UINavigationBarAppearance()
appearance.backgroundColor = .red
UINavigationBar.appearance().standardAppearance = appearance
UINavigationBar.appearance().scrollEdgeAppearance = appearance
UINavigationBar.appearance().compactAppearance = appearance
} else {
UINavigationBar.appearance().barTintColor = .red
}
ViewController.swift
let webConfiguration = WKWebViewConfiguration()
webView = WKWebView(frame: .zero, configuration: webConfiguration)
webView.uiDelegate = self
webView.navigationDelegate = self
view = webView
guard let path: String = Bundle.main.path(forResource: "index", ofType: "html") else {
fatalError()
}
let myURL = URL(fileURLWithPath: path, isDirectory: false)
self.webView.loadFileURL(myURL, allowingReadAccessTo: myURL)
index.html
<!DOCTYPE html>

<meta charset="UTF-8">

<input type="file" name="example" accept="image/jpeg,image/png">

Activity
On an iPad with SafeArea, the height drawn in safeAreaInsets.bottom and Toolbar are different, so there is a gap between the Toolbar and the bottom.
class ViewController: UIViewController {
override func viewDidLoad() {
super.viewDidLoad()
self.navigationController?.setToolbarHidden(false, animated: false)
}
override func viewDidAppear(_ animated: Bool) {
super.viewDidAppear(animated)
let insetsBottom = self.view.safeAreaInsets.bottom
let screenHeight = UIApplication.shared.keyWindow?.bounds.size.height ?? 0
let toolbarFrameY = (self.navigationController?.toolbar.frame.origin.y ?? 0)
print("safeAreaInsets.bottom=\(insetsBottom), toolbar.height with safeArea=\(screenHeight - toolbarFrameY)")
}
}
But, When "Shows Toolbar" is checked in Storyboard, safeAreaInsets.bottom and the height drawn on the Toolbar match.
Why is the behavior different?
Is there any way to deal with this in code?
