Use setFireDate: to reschedule the timer. You'll need to keep track of the timer in an ivar. For example:

@property (nonatomic, readwrite, retain) NSTimer *timer;

@synthesize timer=timer_;

- (void)setTimer:(NSTimer *)aTimer {
  if (timer_ != aTimer) {
    [aTimer retain];
    [timer_ invalidate];
    [timer_ release];
    timer_ = aTimer;
  }

- (void)dealloc {
  [timer_ invalidate];
  [timer_ release];
}

...

self.timer = [NSTimer scheduledTimerWithTimeInterval:...];

...

self.timer.fireDate = [NSDate dateWithTimeIntervalSinceNow:3]; // reschedule for 3 seconds from now
