Must I test the release build which I submit to Apple? How?

I've heard you gotta test the release build as well, and some things can work different in that build than on the debug build. The big question is, how can I bring a release build o开发者_运维问答n my device without the App Store route? Only by Ad Hoc distribution?

You should create a third build configuration in addition to Debug & Release by copying the Release configuration and changing only the code signing to use the distribution signing key for the app. Call the third one "Distribution." By basing the distribution off the "release" build, the two will be identical save for the code signing.

Now, you just need to test the "release" build on your device and when you're happy it works, build the "distribution" and submit that build to Apple.
