问题 I have a SwiftUI view that I want to open a rewarded ad from the Google Mobile Ads SDK when I press a button. The instructions for loading the ads (https://developers.google.com/admob/ios/rewarded-ads#create_rewarded_ad) are in UIKit, and I'm struggling to use them in my SwiftUI app. Is there a way to load the ads using SwiftUI, or if I use UIKit, how do I integrate it into SwiftUI? This is the SwiftUI parent view: struct AdMenu: View { var body: some View { NavigationView { NavigationLink

问题 I'm making a SwiftUI app for macOS and I'd like to use the trackpad as an (x, y) input by detecting the position of the user's fingers. I wanna be able to detect multiple fingers that are resting on the trackpad (not dragging). How do I do that? A similar question has been asked before, but I'm asking again because that was from nearly 10 years ago, the answers are all in Obj-C (one in Swift 3), and I'm wondering if there's an updated methodology. Most importantly, I've no clue how to

问题 I have rewritten my sign in view controller as a SwiftUI View . The SignInView is wrapped in a UIHostingController subclass ( final class SignInViewController: UIHostingController<SignInView> {} ), and is presented modally, full screen, when sign in is necessary. Everything is working fine, except I can't figure out how to dismiss the SignInViewController from the SignInView . I have tried adding: @Environment(\.isPresented) var isPresented in SignInView and assigning it to false when sign in

问题 I'm trying to log screen names in my app but I have like 95% not set in Firebase Analytics. In onAppear for a view I do Analytics.setScreenName("screenName", screenClass: "screenName") Should I do this differently?

As you mentioned, the way the view controller hierarchy of a SwiftUI

问题 Anyone an idea how to create an Alert in SwiftUI that contains a TextField? 回答1: As the Alert view provided by SwiftUI doesn't do the job you will need indeed to use UIAlertController from UIKit . Ideally we want a TextFieldAlert view that we can presented in the same way we would present the Alert provided by SwiftUI : struct MyView: View { @Binding var alertIsPresented: Bool @Binding var text: String? // this is updated as the user types in the text field var body: some View { Text("My Demo
