iOS - Tagged Wrappers
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 tag values can be specified via UIView’s
accessibilityLabel
parameter either from the XCode’s UI Builder or programmatically.
Set tag from UI builder (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)
}
...
}
Set tag 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.registerUIViewController(uiViewController: self)
}
...
}
Where to add the wrappers?
Everywhere you have a white space. Tagged wrappers don’t need to contain ads, it's just for flexibility and future-proofing. Indeed, overloading your app with ads is not the best user experience, but the wrappers don’t need to be filled with ads, that’s why 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.
We can manage which ones are and are not filled from the web interface.
Best practices when adding a wrapper
For Creating the wrappers you need to ensure the wrapper view:
Do not overlap other wrappers on the app content, no matter the size it takes. if it is a space that you have a max Size to it, put it in the tag name.
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. So use as many different tags as possible (like id’s but you can have some of them repeated when it makes sense).
Use a blank (no
subviews
)UIView
as the wrapper view.
Limitations
We can fill either all of the wrappers with a tag or just the first one we find with that tag: if you want to differentiate any wrappers you need to assign a different tag to those. 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 while having the same tag, it’s not possible. We encourage you to ask for advice to our technical support on how to group wrappers.To enable tag lookup in the uiViewController’s view hierarchy and screen navigation tracking you will need to call
R89SDK.shared.registerLifecycle(uiViewController: self)
in theUIViewController.viewDidLoad()
method to explicitly notify theR89SDK
about screen load event. Keep in mind to call it AFTER tag configurations.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.registerUIViewController(uiViewController: self) } ... }
This limitation and R89SDK.shared.registerUIViewController(uiViewController: self)
might be removed in forthcoming versions and replaced with an automatic screen-tracking approach.
