I think you need to add something like
[[NSRunLoop currentRunLoop] addTimer: timer forMode:
NSDefaultRunLoopMode];
for your timers in order to have the run loop run them; otherwise,
I think
you've created objects that actually aren't going to do anything
but sit
there.

Subject: NSTimer
Hi folks,
I have an NSTimer that I'm trying to use to periodicly call a
method.
The timer gets created, but it doesn't call my method when it fires.
Here's my code, do you see anything wrong?
-(void)incrementProgressIndicator;
{
NSLog(@"incrementProgressIndicator"); //Never logs
//progressIndicator is an NSProgressIndicator IBOutlet of this
object
//incrementAmount is a double ivar with a written accessor
if (progressIndicator != nil) {[progressIndicator incrementBy:
[self
incrementAmount]];}
}
-(void)incrementProgressIndicatorEveryTimeInterval:
(NSTimeInterval)seconds iterations:(int)iterations;
{
NSLog(@"incrementProgressIndicatorEveryTimeInterval: %f
iterations:
%i", seconds, iterations);
NSTimer *incrementerTimer;
NSInvocation *incrementerInvocation;
incrementerInvocation = [NSInvocation
invocationWithMethodSignature:
[self methodSignatureForSelector: @selector
(incrementProgressIndicator)]];
incrementerTimer = [NSTimer
scheduledTimerWithTimeInterval:seconds
invocation:incrementerInvocation repeats:YES];
//incrementerTimer needs to be invalidated after it fires
(iterations) times, so we set up a
//second timer to wait (seconds * iterations) seconds and
invalidate
the original timer
[NSTimer scheduledTimerWithTimeInterval:(seconds*iterations)
invocation:[NSInvocation invocationWithMethodSignature:
[incrementerTimer
methodSignatureForSelector:@selector(invalidate)]] repeats:NO];
}
