ios13

问题 Please note that this project was created in Xcode 10. I recently upgraded to Xcode 11 and this happened. I have a UINavigationController that pushes the View Controllers. The initial view controller looks OK. But when I segue to another view controller by pushing it, the second view controller overlapped the status bar. This only happened in iOS 13. I tested on a simulator. Using Xcode 11. The navigation bar's visibility is hidden. Setting the Presentation to Full Screen or Current Context

问题 I am working with a SwiftUI based app that relies on a NavigationView to transition from screens. I have a requirement to set the background color on the navigation bar and have found code that makes this work most of the time.

However, when the app is launched in landscape mode, the bar is the default gray and only updates after the first rotation. Below, I have the minimal amount of code to recreate my

问题 I am using UIMenuController to display custom options. It was working fine with a black background and white text on UIMenuItems till iOS 12.

问题 When using PencilKit in iOS 13/iPadOS, how do you change the content in PKDrawing? For example, can I go through all the lines and change the color or width of the lines? Or for selected lines (via lasso)? Or add a straight line in our own code? 回答1: PKDrawing is listed as an Opaque data object. See this Wikipedia Link for an explanation of opaque data object. Unfortunately strokes are not exposed to us. Our only 2 options currently can be found in the docs under Modifying the Drawing.

问题 I am working with SwiftUI, and I have some issues with the TabBar. I want to hide the TabBar on a specific subview. Have tried with UITabBar.appearance().isHidden = true It only works on the direct views in the TabView. But when I place it in a subview it doesn't work. Have anyone a solution for this? Thanks. 回答1: here's no way to hide TabView so I had to add TabView inside ZStack as this: var body: some View { ZStack { TabView { TabBar1().environmentObject(self.userData) .tabItem { Image

问题 I'm confused about implementing external monitor support via Airplay with SwiftUI. In SceneDelegate.swift I'm using UIScreen.didConnectNotification observer and it actually detects a new screen being attached but I'm unable to assign a custom UIScene to the screen. I found a few good examples using Swift with iOS12 and lower, but none of them work in SwiftUI, since the whole paradigm has been changed to use UIScene instead of UIScreen.
