Ale*_*kis 6 html xcode uinavigationbar ios swift
我在导航栏上使用大标题,当我点击一个单元格进入下一个控制器时,大标题有一个奇怪的动画(如下面的 gif 所示)。它不会立即消失。
我尝试了以下解决方案,但没有(https://www.morningswiftui.com/blog/fix-large-title-animation-on-ios13)
我的代码:
在第一个视图控制器上:
override func viewWillAppear(_ animated: Bool) {
super.viewWillAppear(animated)
navigationItem.title = "New Order"
navigationController?.navigationBar.prefersLargeTitles = true
}

在第二个视图控制器上(带有大标题):
override func viewWillAppear(_ animated: Bool) {
super.viewWillAppear(animated)
navigationItem.title = "Menu"
self.navigationController?.navigationBar.prefersLargeTitles = false
}

法比奥的答案是解决方案,但现在我有另一个问题:
当我点击一个单元格时,导航栏的一部分是黑色的(如下所示)

尝试在第一个视图控制器上插入:

super.viewWillAppear(animated)
navigationItem.title = "New Order"
navigationController?.navigationBar.prefersLargeTitles = true
navigationItem.largeTitleDisplayMode = .always
}

对于第二个问题:在 SceneDelegate 中:var window: UIWindow?
在函数场景中放置此行:
window?.backgroundColor = .yourColor

像这样:
func scene(_ scene: UIScene, willConnectTo session: UISceneSession, options connectionOptions: UIScene.ConnectionOptions) {
// Use this method to optionally configure and attach the UIWindow `window` to the provided UIWindowScene `scene`.
// If using a storyboard, the `window` property will automatically be initialized and attached to the scene.
// This delegate does not imply the connecting scene or session are new (see `application:configurationForConnectingSceneSession` instead).
guard let _ = (scene as? UIWindowScene) else { return }
window?.backgroundColor = .white
}
