问题 I'm trying to implement a dynamic view composed UI elements sent by the backend, meaning it is not known beforehand how many and which UI elements will be displayed, the server sends JSON containing the types of fields that need to be rendered. So for example the sever sends: type: paragraph type: textfield Then I instantiate a class I have for each of those elements and add their views as subviews to my main dynamic view: class DynamicViewController: UIViewController { // array of subviews,

问题 Let's say I have three view controllers. On the first one, I tap a button and present the second view controller modally. On the second one, I tap a button and store the presenting view controller (first), then set the third view controller as the root view controller. Finally, I have a button on the third view controller that grabs the stored controller and sets that as the root view controller. When I restore the first view controller, I find that its presentedViewController property is nil

问题 I have one base class MyViewController: UIViewController initialized by MyViewController.xib with some outlets. I only have set File Owner class in MyViewController.xib to MyViewController , no any init methods in MyViewController.swift (all inherited from UIViewController ), and following line works just as expected: let vc = MyViewController() view property is set, outlets is set. I wish to subclass MyViewController : SecondViewController: MyViewController { override init() { super.init() }

问题 I have a SwiftUI view that I want to open a rewarded ad from the Google Mobile Ads SDK when I press a button. The instructions for loading the ads (https://developers.google.com/admob/ios/rewarded-ads#create_rewarded_ad) are in UIKit, and I'm struggling to use them in my SwiftUI app. Is there a way to load the ads using SwiftUI, or if I use UIKit, how do I integrate it into SwiftUI? This is the SwiftUI parent view: struct AdMenu: View { var body: some View { NavigationView { NavigationLink

问题 The problem is this: I need to be able to get analytics on didSelectRowAtIndexPath throughout a big existing app with lots of tableViews. My first thought of this is doing method swizzling on didSelectRowAtIndexPath: but my app crashes with "unrecognized selector sent to instance" message depending on the stuff is accessed in the original didSelectRowAtIndexPath implementation. Here is how I try to achieve this in a UIViewController category: #import "UIViewController+Swizzle.h"
