ios13

问题 I use the iOS settings app for my app settings. However, since upgrading my device to iOS13, tapping on one of the rows that should lead to a child settings pane (Appearance, Notifications or PDF Export) causes the iOS settings app to crash, with no debug message in my debugger. This happens regardless of whether the app is the current release version compiled in XCode10, or newly compiled in XCode11. I have the following root.plist file, which contains three child settings pages. I have

问题 In previous iOS versions you could detect if the user had bluetooth enabled or not without actually prompting the user's permission to access bluetooth. In iOS13, CBCentralManager now prompts bluetooth permission just to check if they have bluetooth turned on or not, regardless of if the app is actually going to use bluetooth directly. Our app uses Apple's multipeer connectivity framework to communicate between devices (peer to peer) which uses a combination of wifi and bluetooth, or just

问题 In info.plist file I configured URL Identifier and URL Scheme successfully. Also I am able to open app using custom URL. The problem is when app launches first time the method func scene(_ scene: UIScene, openURLContexts URLContexts: Set<UIOpenURLContext>) does not call. I have some dependent functionality based on above method. So when app launches first time I am not able to see anything in my app. Also I added code in method func scene(_ scene: UIScene, willConnectTo session:

问题 I have an issue with systemLayoutSizeFittingSize on iOS 13 beta. I am working on a plugin for NativeScript which uses the systemLayoutSizeFittingSize of the UICollectionViewCell to "measure and layout" the UIView that is in the cell. What I have been doing is: Manually call systemLayoutSizeFittingSize if I need to force a measure/layout of the UIView that is in the cell or Wait for the OS to call systemLayoutSizeFittingSize and again measure and layout the UIView that is in the cell It all

问题 I am using Xcode 11 GM Seed (11A419c). When I run Metal code on iOS 13 simulator and try to access metal device created using MTLCreateSystemDefaultDevice(), it returns nil. How is Metal supposed to run on simulator without this device? Is there any setting in XCode to fix it? I have Macbook Pro retina 2012 model running Mac OS 10.14.6 if that matters. 回答1: Metal is available in iOS 13 and tvOS 13 simulators only when running on macOS Catalina (10.15) or later. This is documented in the Xcode

问题 We have developed an app in iOS 12 which worked really fine. Now in iOS 13 UIPanGestureRecognizer is not working any more. I've search for solutions but didn't find anything. @IBAction func handlePan(recognizer:UIPanGestureRecognizer) { let translation = recognizer.translation(in: self.view) if let view = recognizer.view { let center = view.frame.origin.y + view.bounds.height / 2 if(center <= SliderView.bounds.height && center >= SliderView.bounds.minY) { view.center = CGPoint(x:view.center.x

问题 I am working on Telegram source code from the archived repo and application crashes in every ViewController and I can see the following error. I also tried to comment out some codes but the crash just moves from one class to another. Is there any way to stop traitCollection from causing these crashes?

问题 I've been trying to make an app for iOS 13 using Swift UI but I keep getting this weird error: "ambiguous reference to member 'buildBlock()'". No matter what I do the error won't go away. I tried commenting of sections of code at a time to see which part might have been causing the issue, but the only thing that ever worked was commenting out the entire view. I've tried cleaning my build folder and deleting derived data. I also tried restarting my computer and Xcode multiple times, nothing

问题 I am currently running Xcode 11.0 and iOS 13.1 (beta). I am experimenting with the newly added functionality in iOS 13 of being able to connect to Wifi hotspots where only the prefix is known: Apple Docs This is perfect for headless accessory's Wifi setup, as you would not need to ask the user to switch to the OS settings in order to connect to the accessory's wifi. But unfortunately I cannot make it work as expected. My code ( Swift 5 ): if #available(iOS 13, *) { // The accessory's wifi
