Scenario: There is a developer account, you can add the device to the developer account, the real machine debugging. Now needs to be packaged, installed on the jailbreak phone (this jailbreak phone is not added to the developer account, the other company's people).
Common sense:
No jailbreak, the biggest problem is the device's signature, each program has a corresponding mobile provision file, this file records whether this program is used for publishing or debugging, debugging, is on which device debugging, as well as the corresponding release and debug certificates.
This mobile provision was written in the app when it was bulid. If you use release when you bulid, you can install it on a different device. If you use Debug when you are Bulid, you can only install it on the device specified by mobile provision .
Method:
1 Selecting an iOS device
2 Edit schema for release
3 Build
4 Drag the app to itunes
5 drag to Desktop to generate IPA file
