RE: NSTimer



According to
<http://developer.apple.com/documentation/Cocoa/Conceptual/Timers/index.html
> that's not the case:

"Note that run loops retain their timers, so you can release the timer after
you have added it to a run loop."

Since +scheduledTimerWithTimeInterval:invocation:repeats: adds it to the
default run loop, it should live past the end of this method just fine.

These NSTimers are autoreleased, and are likely getting deallocated
before they can do anything.  You should retain them, keep a reference
to them, and then release them once you're done with them.
