Don't make two views. Start with auto-resizing (struts and springs). That
should be enough in 95% of cases. If you have

No need to make a new image. Jus
Hi all. I'm having a layout problem on all my screens after they're
rotated. It seems as though the view loses all knowledge of the
navigation bar at the top after a rotation, so subviews are shoved up
under it. Check it out:

Resolved. Turns out that doing this after rotation will re-align everything:
[self.navigationController.view layoutSubviews];
Kinda seems like the framework would call that, but I guess not.

The OP wants a solution for iOS. lock/unlockFocus only exist in NSView, not
UIView.
FWIW, I think you (that is, the OP) should start with the simplest solution
available (e.g. Steve's suggestion), test performance, and only optimize if
needed. Don't try to optimize if it's not actually require

Incorrect. There are many reason to have a seedable PRNG, the least of which is
the ability to reasonably debug the randomness. That an arc4ra

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 seei
I don't think random/srandom are superseded. I use them myself for game
creation. The game just has one number associated with it, I use that to seed
random and I can completely recreate the whole game from that one number.
I use the slightly more complicated initstate version. I see no reason

I've made an iOS app that allows users to organize their contacts into groups

It is working great, except I am getting reports that it is failing when trying

You are trying to set seed to a value that is something like
3,281,585,690,000; seed cannot handle this value so it will be set to
4294967295, at least on my machine.

I've seen gnu documentation for srandom that suggest the equivalent of Kevin's
suggestion, namely "srandom(time(0))". Not sure if using the NSDate has any
advantage over a call to time() and it would avoid this type of thing (gnu is
likely to ensure time() and srandom() work correctly together).

It’s never a good idea to seed a RNG with something guessable like this. (An
old exploit against the Netscape browser’s SSL implementation was made possible
in part by doing exactly that.)
All you have to do is call srand

Not all applications of random() have anything to do with security...
