Custom View

​

Add Custom view to your project

1. Create a class that conforms to ChoicelyExternalViewControllerFactory protocol:
   class YourCustomViewControllerFactory: ChoicelyExternalViewControllerFactory {
   
       func createViewController(choicelyNavigationitem: ChoicelyNavigationItem?) -> ChoicelyController? {
           return nil
       }
   }
   
2. Declare all your custom views usage inside it’s createViewController() method:
   UIKit

   SwiftUI

   let yourCustomUrl = "choicely://special/your_custom_url"
   let internalUrl = choicelyNavigationitem?.internalUrl
   
   if internalUrl.contains(yourCustomUrl) == true {
     return YourCustomViewController()
   }
   
   // In order to return YourCustomViewController make it a subclass of ChoicelyViewController.
   
   Custom navigation URLs like "choicely://special/your_custom_url" can be set and configured in Choicely Studio.
   This is how you can create custom navigation URLs:
   
3. Set the custom url, click “Add Navigation” and save the changes by clicking “Update” button in the top right corner.
4. Here is the example of fully configured ChoicelyExternalViewControllerFactory:
   UIKit

   SwiftUI

   import ChoicelyCore
   
   class YourCustomViewControllerFactory: ChoicelyExternalViewControllerFactory {
   
     func createViewController(choicelyNavigationitem: ChoicelyNavigationItem?) -> ChoicelyController? {
       let yourCustomUrl = "choicely://special/your_custom_url"
       let internalUrl = choicelyNavigationitem?.internalUrl
   
       if internalUrl.contains(yourCustomUrl) == true {
         return YourCustomViewController()
       }
   
       return nil
     }
   }
   
5. Create an instance of YourCustomViewControllerFactory class and just before ChoicelySDK.initialize(...) assign it to ChoicelySDK.settings.externalViewControllerFactory:
   ChoicelySDK.settings.externalViewControllerFactory = YourCustomViewControllerFactory()
   
   To learn more about other ChoicelySDK settings explore them in XCode with (⌥)+click.
6. That’s it! You’re ready to use your custom views.
   You can mix Choicely content like Articles and Surveys with your own UI logic inside one custom view.
