I submitted the iphone app to the app store, It was rejected for the point from the resolution center:
2.2 Apps that exhibit bugs will be rejected
We found that your app exhibited one or more bugs, when reviewed on iPhone 4 running iOS 5.1.1, on both Wi-Fi and cellular networks, which is not in compliance with the App Store Review Guidelines.
I have not used any of the network connection related codes. This app will simply create a PDF and send via default mail composer(MFMailComposerViewController) that’s it..
Is there any possibility to resolve this issue.
MFMailComposerViewController is network related code. You need to handle the fail condition with what to do if the app is not connected to a network and so it can’t send it’s email. I suggest testing your application to see how it handles not being on a data network.
You can handle what happens when the email is not sent properly in the delegate method.
