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];


}
