问题 The same error is also triggered setting up Multipeer Connectivity (which uses Bonjour). The code I was using for initiating Bonjour browsing and Multipeer Connectivity was modified from the Apple sample code and worked fine under iOS 13. 回答1: You need to add the following keys to the Info.plist: NSLocalNetworkUsageDescription and NSBonjourServices . E.g. <key>NSLocalNetworkUsageDescription</key> <string>Reason for using Bonjour that the user can understand</string> <key>NSBonjourServices<

问题 I have a collection view, and each collection view cell will have a table view which will have different data for each collection view cell. The collection view is done using a storyboard and works fine, but I can not seem to get a UITableView to work inside of it. The Collection view code is below and any help is appreciated. Ideally a technique that allows me to use storyboard to customise the tableview cell, and I am using Swift 4. extension StoryboardViewController:

问题 I am using xCode 7 beta and swift, and storing my data using Parse.com. In which method in the UITableViewController should I be asking for data from my database? I need to ensure it is all present by the point in the lifecycle of the controller at which the cells need to be presented. Is there anyway to guarantee this if I am loading data asynchronously? 回答1: viewDidLoad would be a good place for this but there might be a few second difference between displaying a blank tableView and when it

问题 I am trying to generate the face mesh from the AR face tutorial with proper vertices label using SCNText. I follow the online tutorial and have the following: enterextension EmojiBlingViewController: ARSCNViewDelegate { func renderer(_ renderer: SCNSceneRenderer,didUpdate node: SCNNode,for anchor: ARAnchor) { guard let faceAnchor = anchor as? ARFaceAnchor, let faceGeometry = node.geometry as? ARSCNFaceGeometry else { return } faceGeometry.update(from: faceAnchor.geometry) } func renderer(_

问题 My app is basically a phone call over MultipeerConnectivity. Here is how I'm setting up the audio session: Note that recordingSession is of type AVAudioSession and captureSession is of type AVCaptureSession. func setupAVRecorder() { print("\(#file) > \(#function) > Entry") do { try recordingSession.setCategory(AVAudioSessionCategoryPlayAndRecord) try recordingSession.setMode(AVAudioSessionModeVoiceChat) try recordingSession.setPreferredSampleRate(44100.00) try recordingSession

I am aware that if you want to handle local notifications when they are received when the app is terminated you are required to access the local notification

问题 Is there a way in iOS to run a fade animation on a UIView (UILabel specifically) that will fade in with a swipe action (so if it paused half way, the left side is visible, right side invisible and middle some gradient between).
