ios11

My app reports and records location, altitude, rotation and accelerometer data (DeviceMotion) while in the background. This works fine on ios 10.3.3. On IOS 11, I no longer have access motion data while the device is locked. Altitude data and location data is still streaming to the console, though. Has something changed in IOS 11 that prevents me from accessing motion data or am I doing trying to access it in a way that Apple now blocks like OperationQueue.main Here is how I'm starting motion updates. If the phone is unlocked, all works fine. If I locking the phone, no more updates.: let

Prior to Xcode 9 and iOS 11 I had a UITextView within a UITableViewCell that contained multiple links. Each link worked as expected, however since upgrading to iOS 11 and Xcode 9, the links no longer work. The UITextView doesn't appear to recognise any touch interaction with func textView(_ textView: UITextView, shouldInteractWith URL: URL, in characterRange: NSRange, interaction: UITextItemInteraction) -> Bool never firing. Has anyone else found this same problem after upgrading? Turns out there wasn't a problem after all. Changes in the way UITextView responds to touches in iOS11 means that

How to draw a border to highlight a SCNNode and indicate to user that the node is selected? In my project user can place multiple virtual objects and user can select any object anytime.

I want to use Apples visual format language to constrain a view to the new Safe Area Layout Guide in iOS 11. However, I get an exception: -[NSLayoutYAxisAnchor nsli_superitem]: unrecognized selector sent to instance 0x1c447ed40 //Make View Dictionary var views: [String: Any] = ["left": self.leftContainer] //Check swift version and add appropriate piece to the view dictionary if #available(iOS 11, *) { views["topGuide"] = self.view.safeAreaLayoutGuide.topAnchor }else{ views["topGuide"] = self.topLayoutGuide } //Make the constraint using visual format language let leftVertical =

I am trying to use the new large title system in iOS 11 using Swift. When the title gets too long (see image example), it adds ... instead of line breaking or shrinking the text size. How can I add a line break? Here is some of the code I'm using to set up the title: self.navigationController?.navigationBar.prefersLargeTitles = true self.navigationController?.navigationBar.largeTitleTextAttributes = [NSForegroundColorAttributeName: MyGlobalVariable.themeMainColor] self.navigationController?.navigationBar.largeTitleTextAttributes = [NSFontAttributeName: UIFont.systemFont(ofSize: 22)]
