Should the rfc1034identifier be removed from the CFBundleIdentifier in plist file?


The :rfc1034identifier just formats it (if needed) so there are no illegal characters* in the bundle name. You're unlikely to have a product that is called by an illegal character but it's not impossible.

I'd leave it in there but it's really up to you.

(Actually, most of the time I just hardcode the bundle - that way if the product name changes for any reason, it's still got the same bundle identifier when I come to update it in the app store)

*such as a space or a dot - they will be replaced with a dash so 'My Game' would become 'My-Game'


My understanding (though trial and error) is that the identifier must be unique for each app that you submit, or load onto an iOS device via iTunes or directly. So even if your used a '*' as the identifier (1), each app must have it's own unique identifier. So, unless you change the PRODUCT_NAME from app to app, you want to append something after ${PRODUCT_NAME:rfc1034identifier}, to make sure it's unique. I add a date in YYMMDD format to do this : ${PRODUCT_NAME:rfc1034identifier}110524 (for May 24, 2011)

(1) ie: in the provisioning portal, when you create a a new app id, you put a '*' in the 'Bundle Identifier (App ID Suffix)" field
