I got this soon after launching the app, just trying out all three tools. If it's at all interesting, my app was in the middle of pushing a new view controller when I managed to trigger Bugshot.

Oh, one more thing; I had also just gone to send a Bugshot mail, but then cancelled out of the mail composer.

Once again with feeling (and a stack trace, maybe because I was running in the simulator, with the Bugshot project open?)

I can confirm this is repeatable on an iPhone 5s and the 64 bit and 32 bit simulators.

Ok, I've worked it out.

The unrecognised method was defined on a category and, because the category was included in a static library, it wasn't being linked properly. To fix this you need to add the -ObjC flag to the "Other Linker Flags" of the project that uses the static library along with the -lBugshotKit. This could probably be noted in the README.md.

As an aside, in order to make a .a that would work in simulator builds I had to set BugshotKit's Build Active Architecture Only to No for Debug and Release builds. Should that be made the default?
