问题
I am a developer at iPhone Developer Program assigned to the project for the company. I would like to buy my own licence to develop as an independent programmer. How to do it? Do I need another Apple ID?
回答1:
No, you can be a member of multiple development teams with a single Apple ID. The developer website will ask you which team you'd like to work on when you sign in.
回答2:
I highly recommend not using the same Apple ID for multiple developer programs.
You can do it, but anytime it prompts you to log in, it also prompts you to "Select Your Team". As a separate step. Both on the web and in XCode.
It slows me down and I haven't found any way to make it always choose one as the default rather than asking every time.
[Update: My original answer is well over a year old, and I had been living with the annoyances for a while before posting. I just had our administrator send me a new invitation to my corporate email address so I wouldn't have the conflict. It took me almost no time at all to get my profiles set up again and it's so much nicer to not have to "choose your program" all the time.
So if you set things up this way and you've just been living with it, don't. Save yourself the annoyance and time and just get re-added to the program with a different email address.]
