iAd refusing to display

Question

iAd framework is doing my nut. AGAIN!

Please someone help me towards sanity.

Yesterday was working on the simulator, today it isn't. After an hour of raging at it I actually plug in my brain and log the error (iirc this is on the simulator)

Error Domain=ADErrorDomain
Code=3 "The operation couldn’t be completed. Ad inventory unavailable"
UserInfo=0x5a5bb50 { ADInternalErrorCode=3,
NSLocalizedFailureReason=Ad inventory unavailable }

then I try a reboot.

on the simulator:

Error Domain=ADErrorDomain
Code=4 "The operation couldn’t be completed. Application has iAd Network configuration error"
UserInfo=0x5839510 { ADInternalErrorCode=4,
NSLocalizedFailureReason=Application has iAd Network configuration error }

now try on the device:

Err Domain=ADErrorDomain
Code=1 "The operation couldn’t be completed. (ADErrorDomain error 1.)"
UserInfo=0x19c8c0 {}

finally I find something on Google:

http://useyourloaf.com/blog/2010/11/28/ad-inventory-unavailable-with-ios-42.html

This guy is saying it seems to be an issue with >= iOS 4.2.

So I try again using iOS 4.0 iPhone simulator

Yay, I get yet another error code.

Error Domain=ADErrorDomain Code=0 "Invalid data."

On your device, go to the Settings app. Tap Developer. Under iAd Developer App Testing, tap Fill Rate. Select the error rate you want to test.
