> I'm using random(), but every time I run my app I get the same sequence, despite having this code in my app delegate's -appDidFinishLaunching method. Clearly I'm not seeding it right, though I can't see why - I get a different value for seed every time. What gives?

I'm not sure what your problem is, but I believe arc4random() has
superseded random() for a while now.
