Continuing the discussion with only myself, so far….
I had the idea to make a trivial test app which just has a PDFView and a “Load”
button.
So I created the app on 10.9 with Xcode 5.0.2. It’s just a vanilla NSDocument
app with a PDFView and a button. Compiles and runs fine on 10.9.
So then I thought I will change the Deployment Target to 10.6.8, the Base SDK
to 10.8, and I switched off auto layout for both the document nib and the main
menu nib, and also set them to build for 10.6 and later.
Archived the app and distributed as just an unsigned application.
Copied to the 10.6.8 test machine, and the app won’t run. I get the console
error:
"unable to load nib file: MainMenu, exiting”
I then dug through the build settings of the main app that’s giving me these
PDFView problems, but I don’t see anything different there. Clearly I’m missing
something, can someone spot what it is?
Many thanks,
Martin
