thanks everyone for the answers.
i agree that Ashley's method is far more readable than using modulus
calculations, so i'll look into that further as i can't seem to get it
working yet.
currently, i have this working using modulus calculations, but it
starts at 00 for the hours and minutes...
/* snip */
- (void)updateTime:(NSTimer *)theTimer
{
NSTimeInterval now = [NSDate timeIntervalSinceReferenceDate];
NSTimeInterval interval = now - startTime;
//Tag #1 x 3600 Seconds = 3600 Seconds = 2 Hours.
//Tag #2 x 3600 Seconds = 7200 Seconds = 2 Hours.
//Tag #3 x 3600 Seconds = 10800 Seconds = 3 Hours.
int hoursSelected = ([self timeMenuSelection] * 3600);
NSTimeInterval remaining = hoursSelected - second;
if (remaining >= 0)
{
int hours = remaining / 3600;
int minutes = (remaining / 60) % 60;
int seconds = remaining % 60;
NSLog(@"%.2d %.2d %.2d ", hours, minutes, seconds);
}
else
{
NSLog(@"TIME'S UP!");
[killTimer invalidate];
[killTimer release];
killTimer = nil;
}
}
