Can an NSTimer be rescheduled after firing, and after another trip
through the run loop?
I'd like to "reschedule" a NON-repeating timer in my own code. I
assume that in the simple case it would be something like:
- (void) handleTimer: (NSTimer *) aTimer
{
// ... do things ...
[aTimer setFireDate: someTimeInTheFuture];
[[NSRunLoop currentRunLoop] addTimer: aTimer forMode:
NSDefaultRunLoopMode];
}
I'm pretty sure that this is legal — am I right?
No, as you suspected farther down in your message. NSTimers which are
not repeating are one-shot -- they cannot be rescheduled. Create a
new NSTimer, when you next need it, and add it to the run loop. [And
also self.myTimerIvar = nil; in your timer handler as you thought.]
