inRead - MoPub mediation

This article shows you how to deliver Teads Native ads on your application using the MoPub Mediation adapter.

Using CocoaPods to have Teads Mopub mediation plugin will automatically import the Teads inApp SDK framework.

Sample App on GitHub
Teads inApp SDK iOS sample App


  • Platform: iOS 14.5+
  • Xcode: 12.5+
  • MoPub SDK: 5.13+


Before installing the Teads MoPub adapter, you will need to integrate MoPub SDK into your application.


If your project is managing dependencies through CocoaPods, you just need to add this pod in your Podfile.

It will install the Teads adapter along with the Teads inApp SDK.

  1. Add Pod named TeadsMoPubAdapter your Podfile:
pod 'TeadsMoPubAdapter', '~> 5.0'
  1. Run the following to install the adapter in your project.
$ pod install --repo-update to install
  1. Follow the Defining a Custom Event step below to finish the integration.


  1. Integrate the latest version of the Teads inApp SDK to your project.
  2. Download the latest release of TeadsMoPubAdapter.
  3. Drop adapter files in your iOS project.
  4. Follow the Defining a Custom Event step below to finish the integration.

Defining a Custom Event

In order to display a Teads ad using MoPub, you need to create a custom event.

See this article for more test PIDs serving different creative formats.

Name Value
Custom Event Class TeadsMoPubAdapter.MPAdapterTeadsBanner
Custom Event Class Data {"PID": "#PID#"}


Don't forget to replace the #PID# with your Teads placement ID.



MPAdView automatically refreshes an ad unit at a time interval specified via the MoPub web interface. You need to disable automatic refreshing content

You have the ability to pass extra parameters in order to customize third-party ad network settings. For Teads, you need to pass TeadsAdapterSettings.

  • Register your TeadsAdapterSettings into MPAdView using register.
let settings = TeadsAdapterSettings { settings in
let mopubAdView = MPAdView(adUnitId: MOPUB_AD_UNIT_ID)
mopubAdView.delegate = self
mopubAdView.register(teadsAdSettings: settings)
mopubAdView.stopAutomaticallyRefreshingContents() //disabling auto refresh content
mopubAdView.loadAd(withMaxAdSize: kMPPresetMaxAdSizeMatchFrame)

Ad Resizing

The code below must be implemented to enable the resizing of the mediated ad slot making possible the rendering of square and vertical creatives.

Register to ad resizing through TeadsAdapterSettings by providing your delegate class and the MPAdView that need to be resized

var mopubAdView: MPAdView!
@IBOutlet weak var slotHeight: NSLayoutConstraint! // set to 0 on InterfaceBuilder

let adSettings = TeadsAdapterSettings { settings in
    settings.registerAdView(mopubAdView, delegate: self)

Simply conform to the Teads delegate TeadsMediatedAdViewDelegate and implements the didUpdateRatio function.

You can implement delegate as below, we keep internally a weak reference to it, so it's not retained when you don't need it anymore:

func didUpdateRatio(_ adView: UIView, adRatio: TeadsAdRatio) {
    let height = adRatio.calculateHeight(for: slotView.frame.width) // call calculateHeight
    slotHeight.constant = height //update NSLayoutConstraint of the slot
