问题 So I'm having a weird issue with the new large titles in iOS 11. Instead of me trying to badly and confusingly explain the issue here is a 10-second screen recording of what is happening: Screen recording of issue on YouTube As you can see there is a weird black bar that appears when transitioning between a view controller that has navigationItem.largeTitleDisplayMode = .never And one that is set to .always Thanks in advance! 回答1: Before the transition set this: self.navigationController?

问题 I'm using a UIImagePickerController with allowsEditing enabled to share images in an App, but found that cropped image is offset for devices running iOS 11 only. My UIImagePickerControllerDelegate implementation is quite simple, just standard actions: func imagePickerController(_ picker: UIImagePickerController, didFinishPickingMediaWithInfo info: [String : Any]) { let image = info[UIImagePickerControllerEditedImage] as! UIImage imageView.image = image picker.dismiss(animated: true,

问题 I'm running the Apple iOS11 example Adding Content to Apple Music on Xcode Version 9.0 beta 3 (9M174d) . I get a Ambiguous use of 'play() in /adding-content-to-apple-music/AppleMusicSample/Controllers/MusicPlayerManager.swift:78:9: Ambiguous use of 'play()' The suggested solutions to explicitly define the selector in order to avoid the ambiguity like: let play = #selector(musicPlayerController.play) did not work in this case.

问题 I have a horizontal paging UIScrollview , following is my VFL constraints for leading/trailing H:|-0-[ScrollView]-0-| (aligned to superview).

问题 I am working on an Augmented Reality iOS app for which i am using ARKIT of iOS 11 beta. I am using ARSCNView(SceneKit) to render my .scn object. I have followed the sample given by apple in order to create an ARSession(https://developer.apple.com/sample-code/wwdc/2017/PlacingObjects.zip). Is it possible to place the 3D model with custom background instead of camera? Like user can select the background color or can provide custom 2D photos as background? 回答1: Your view has a scene property

问题 I'm using this CALayer extension: var borderUIColor: UIColor { set { self.borderColor = newValue.cgColor } get { return UIColor(cgColor: self.borderColor!) } } I thought that maybe because of this extension my borderColor of the Submit button from the bottom of the page doesn't change to white (as I want it to be): But no, I hooked up an IBOutlet and tried to set directly the color like this: submitButton.layer.borderColor = UIColor.white.cgColor Did it in viewDidLoad , viewWillAppear and

问题 I am looking to add a billboarding effect that is similar to this application: https://twitter.com/marpi_/status/897130955105644544 I would like SCNodes that use SCNText geometry to always face the camera. I have attempted with out success: SCNLookAtConstraint with sceneView.pointOfView as the target, but this rotates the node to face away from the camera, resulting in backwards text, and unable to change the nodes position or euler angle. Out of the box, an SKLabelNode will always face the
