问题 I am trying to set up my onboarding screen in the SceneDelegate. When I run the code below, it compiles, but just goes to a black screen. They're many great onboarding tutorials for AppDelegate, but very few for the new SceneDelegate with iOS13. I took this tutorial and tried to apply it to SceneDelegate, but I can't get it to work: https://www.youtube.com/watch?v=y6t1woVd6RQ&t=537s This is my scene delegate code. var window: UIWindow? func scene(_ scene: UIScene, willConnectTo session:

问题 I made a custom class for this. But it works only for top left corner, not the others: @IBDesignable public class RoundedView: UIView { @IBInspectable public var topLeft: Bool = false @IBInspectable public var topRight: Bool = false @IBInspectable public var bottomLeft: Bool = false @IBInspectable public var bottomRight: Bool = false @IBInspectable public var cornerRadius: Int = 0 public override func awakeFromNib() { var options = UIRectCorner() if topLeft { options = options.union(.topLeft)

问题 I am making an app where the user has to double tap a segue to move to the next storyboard, but I cannot find anywhere where it tells you how to do this. Does anyone know how I can achieve this? 回答1: If you do this in Interface Builder with a storyboard: Drag a tap gesture recognizer from the object library onto your view. Make sure the view you dragged it to has "user interaction enabled" checked. Select the tap gesture you added to your scene (which you can find in your document outline on

I have error in one of my Storyboard: error: IB Designables: Failed to render and update auto layout status for MapViewController: dlopen(GoogleMaps.framework, 1): no suitable image found.

It causes whole storyboard to be blank. 回答1: Use GMSMapView manually by writing code in simulator; Instead of using

问题 I have a UIViewController which was created in a storyboard and has been assigned a storyboard id. This UIViewController is instantiated in various places in code and therefor it didn't make sense to create segues from all the different locations. The view controller needs to be contained in a UINavigationController in order to function properly because it uses the various navigation bar items and can push additional view controllers. The view controller is instantiated from code as follows:
