I downloaded an SDK (for Mavick drones) and built the sample app for the simulator - everything was fine! However, when I built to run on my iPhone, it spawned a number of keychain request windows for giving permissions to code signing. There seemed to be hundreds, so I clicked 'deny' on one, and everything stopped.
Now however, every time I try to build the app for my iPhone, code signing fails with unknown error -1=ffffffffffffffff
. I've tried restarting Xcode, cleaning the project etc, but nothing seems to fix this.
What can I do to get code signing working again?
