Crash with message "Could not load NIB in bundle"...'MPAdBrowserController'

[Danny_Saladbowl]

I am developing Unity3D game with Mopub for mediation and have a problem with iOS build.

I integrated Mopub Unity plugin version is 4.7.1.
The networks for mediation are Chartboost V, AdMob, and UnityAds.
For each network, I integrated proper version directed by “Supported Mediation Partners” page.
Chartboost ios version 6.4.0,
AdMob ios version 7.1.0,
UnityAds ios version 1.5.6.

Once I used to have problem for building iOS version, but I got through the issue by only adding
Chartboost.framework and GoogleMoblieAds.framework into xCode project.

But when I run the game and if I click some banners and interstitial ads, it crashes with following error.

‘NSInternalInconsistencyException’, reason: ‘Could not load NIB in bundle: ‘NSBundle </var/mobile/Containers/Bundle/Application/51D07C3A-279E-4AC0-A7D0-ACC044B2284F/apple.app/MoPub.bundle> (not yet loaded)’ with name ‘MPAdBrowserController’’

Once I tried to solve this by putting MPAdBrowserController.xib file, but the crash still happened.

Any clues to solve?

Thanks in advance.

Responding to an old question, but posting a solution for future readers:

1. You need to add this file to your project: MoPub.framework/Versions/A/Resources/MoPub.bundle

2. You also need the right security settings in your Info.plist to allow URLs from ads to be opened in the MoPub Ad browser. This is recommended:

<key>NSAppTransportSecurity</key>
    <dict>
        <key>NSAllowsArbitraryLoads</key>
        <true/>
        <key>NSExceptionDomains</key>
        <dict>
            <key>yourdomain.com</key>
            <dict>
                <key>NSIncludesSubdomains</key>
                <true/>
                <key>NSThirdPartyExceptionRequiresForwardSecrecy</key>
                <false/>
            </dict>
       </dict>
  </dict>
