Weird. Setting a breakpoint on srandom, setstate or srandomdev never triggers except for my own call of it. Using srandomdev doesn't change anything.
Switching to arc4random() gives me a varying random sequence, so that's a usable solution to my problem. But the behaviour with random() I'm seeing is mysterious. --Graham On 27/05/2011, at 11:15 AM, Dave Keck wrote: >> 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.
