ios13

问题 A large part of my app consists of web views to provide functionality not yet available through native implementations. The web team has no plans to implement a dark theme for the website. As such, my app will look a bit half/half with Dark Mode support on iOS 13. Is it possible to opt out of Dark Mode support such that our app always shows light mode to match the website theme? 回答1: First, here is Apple's entry related to opting out of dark mode. The content at this link is written for Xcode

CFDataRef passwordData = NULL; OSStatus keychainError = noErr; keychainError = SecItemCopyMatching((__bridge CFDictionaryRef)returnDictionary, (void *)&passwordData); NSString *password = [[NSString alloc] initWithBytes:[(__bridge_transfer NSData *)passwordData bytes] length:[(__bridge NSData *)passwordData length] encoding:NSUTF8StringEncoding]; after execute above code segment, password variable value is {length=32,bytes

问题 Since apple has deferred the "Always Allow" permission and only OS can and will ask for that permission based on its own convenience, it is hard to understand what all the scenarios are. If you see the WWDC video: https://developer.apple.com/videos/play/wwdc2019/705/ The guy clearly says at 04:14, "you ask for requestAlwaysAuthorization, apple provides you with the max option of "While In Use", but at the same time the delegate callback says, the app has "Always Allow permission"". This works

问题 I am trying to render an overlay (polygon) on the map using swift MapKit. I can render successfully but when I zoom out too much then zoom in again, all the rendered polygons get disappear. How can I prevent that from happening and force the rendered polygons to stay on the map at all zoom scales? I am using MapKit and MKPolygonRenderer. I add the polygons to the map using the following method in my viewController: // function to add polygon overlay to the map private func addPolygonsToMap()

问题 I need to modify the headers of the request when the request fails but the request doesn't change when I modify the request in retryWhen Here is my implementation: func makeRequest(serviceRequest: URLRequest) { let maxRetry = 2 var localRequest = serviceRequest request(request: localRequest).retryWhen { errors in return errors.enumerated().flatMap { (arg) -> Observable<Int64> in localRequest.setValue("someValue", forHTTPHeaderField: "someKey") let (index, error) = arg return index <= maxRetry

问题 I'd like to detect a modal dismissal in the view controller that's presenting the modal. This method works amazing for detecting the new iOS 13 swipe dismissal on the new card modals: override func prepare(for segue: UIStoryboardSegue, sender: Any?) { if segue.identifier == "MyIdentifier" { segue.destination.presentationController?.delegate = self } } extension MyController: UIAdaptivePresentationControllerDelegate { func presentationControllerDidDismiss(_ presentationController:

问题 i have this struct ContentView: View { var body: some View { ZStack(alignment: Alignment.bottom) { List { Text("Default text").foregroundColor(Color.red) } TextField("Placeholder", text: .constant("")) .frame(minHeight: 30) .cornerRadius(8.0) .padding(10) .background(Color.blue) } } } Actually, when i focus on the TextField, keyboard hide this textfield.
