At work today I got several people to download my new Film Quiz app. While it worked for some, it didn’t work for others. I was a little confused by this. The only thing I could work out was that if the iOS version was below 4.2 it crashed when you pressed the start quiz button.
After I got home I decided to look into this problem in XCode. I compiled and ran for iOS 4.0 and ran into the error.
What I found was that the iAd banner had changed slightly in iOS 4.2. Version 1.0 of Film Quiz was only tested on iOS 4.3. So there we have it. After a quick Google I found the solution.
Version 1.1 has now been uploaded to Apple for approval and will shortly be available for download.
