as xcode 3 and xcode 4 is totally different. i'm a bit lost to submit app to app store.
Do i still need to duplicate "Release" to create "iphoneDistrubition" configuration. Or can I straight away use Release?
Is Archive in xcode4 = Build in xcode3 for the purpose of submission app.
If Archive = Build, the icon of the app is very blur in xcode4 organizer. Is that normal?
Is there any other additional steps to follow in xcode4 to submit app to appstore.
Thanks for any help. =)
Xcode 4 makes it easier to submit.
As you have discovered, all you have to do is archive.
The blurry icon is expected behavior as it is a bigger square than on the device.
After you archive you will have the option to submit to the app store, just make sure you are using the right provisioning profile and you will be good to go.
It is useful to know xcode 4 also allows you to do the validation test before submitting so when you submit you are certain there are no problems.
Hope it helps!
