My application was rejected due to the following reasons:
You and Your Applications (and any third party with whom you have contracted to serve advertising) may use the Advertising Identifier, and any information obtained through the use of the Advertising Identifier, only for the purpose of serving advertising. If a user resets the Advertising Identifier, then You agree not to combine, correlate, link or otherwise associate, either directly or indirectly, the prior Advertising Identifier and any derived information with the reset Advertising Identifier." Note: iAd does not use the
AdSupport.framework,ASIdentifierManager, or the Advertising Identifier. Therefore they are not required for iAd implementations and should not be included in your app for iAd support. If your app is serving ads, please: - Ensure that you have tested your app on a device, not just the simulator, and that you have removed all previous versions of your app prior to testing - Provide us the steps to locate ads in your app If your app does not serve ads, please check your code - including any third-party libraries - to remove any instances of: class:ASIdentifierManagerselector:advertisingIdentifierframework:AdSupport.framework
I have tested my app on a device and simulator and it does show You're Connected to iAd test banners. It doesn't let me log into the iAd Workbench so maybe that's the issue?
If iAd is the only advertising network you're using you need to answer No to the following question when submitting your application to the App Store:
Does this app use the Advertising Identifier (IDFA)?
Also, make sure your project does not import the AdSupport.framework. iAd does not use the AdSupport.framework, ASIdentifierManager, or the Advertising Identifier so they are not required and should not be included in your application.
