What Are They?

The tagged wrapper is an iOS UIView with a requirement to have accessibilityLabel specified, either from the XCode UI builder or programmatically. This is used to find the views in the Single tag where you want us to add the monetization inventory. You need to add as many as you can, remember that placing a tagged wrapper does not mean we need to use it.

Example

As mentioned tags are specified by using the accessibilityLabel to set the tag value, and that can be specified either from the XCode UI Builder or programmatically,

Set From Xcode (recommended)

Here is what it looks like in the UI Builder. Here we have a blue wrapper on top and a green one on the bottom. Accordingly, the top wrapper has specified to have a tag named top_wrapper_tag and the one in the bottom bottom_wrapper_tag.

In this case, the UIViewController looks like this

import UIKit
import R89SDK
class MainViewController: UIViewController {
    ...
    override func viewDidLoad() {
        super.viewDidLoad()
        ...
        // This line is necessary to inform R89SDK about app navigation.
        R89SDK.shared.registerUIViewController(uiViewController: self)
    }
    ...
}

Programmatically (alternative)

As an alternative approach, we can specify the accessibilityLabel using code, here is the equivalent setup but from the UIViewController.

import UIKit
import R89SDK

class MainViewController: UIViewController {
    
    @IBOutlet var topWrapperUIView:UIView!
    @IBOutlet var bottomWrapperUIView:UIView!
    ...
    override func viewDidLoad() {
        super.viewDidLoad()
        ...
        // Setting tags programmatically 
        topWrapperUIView.accessibilityLabel = "top_wrapper_tag"
        bottomWrapperUIView.accessibilityLabel = "bottom_wrapper_tag"
        // This line is necessary to inform R89SDK about app navigation.
        R89SDK.shared.registerLifecycle(uiViewController: self)
    }
    ...
}

Where To Add The Wrappers?

While it is true that filling your app with ads to the brim is not the best user experience, we recommend you add the wrappers everywhere where there is a blank space on the screen. Even if you do not want to fill them in, it is okay. We can manage which ones are filled and which are not from the web.

Best Practices When Adding a Wrapper

Creating views, you need to make sure the wrapper view:

• Do not overlap other wrappers or the app content.

• Every blank space is a good space for a wrapper (even if you do not plan to use it).

• Do not use only one tag for all of your wrappers, it will be hard to configure your monetization and change it according to your needs.

Limitations

• We can fill either only one wrapper with a tag or all of them: if you want to exclude some wrappers you need to put a different tag to those views, that is grouping. E.g.: if you want us to fill a wrapper at the bottom of the screen that has the tag ads_wrapper we can fill that. However, if you have multiple wrappers with the same tag, and you want to fill all of them and exclude some others while having the same tag, it’s not possible. We encourage you to ask for advice from our technical support on how to group wrappers.

• To enable tag lookup in the uiViewController’s view hierarchy you will need to call R89SDK.shared.registerLifecycle(uiViewController: self) to register viewController in the SDK. Keep in mind to call it AFTER tag configurations.

  import UIKit
  import R89SDK
  
  class MyViewController: UIViewController {
      
      @IBOutlet var topWrapperUIView:UIView!
      @IBOutlet var bottomWrapperUIView:UIView!
  
      override func viewDidLoad() {
          super.viewDidLoad()
          //Tag configurations 
          topWrapperUIView.accessibilityLabel = "top_wrapper_tag"
          bottomWrapperUIView.accessibilityLabel = "bottom_wrapper_tag"
          //Registration of UIViewController
          R89SDK.shared.registerLifecycle(uiViewController: self)
      }
  }
