The todayString has to change as device time changes. That means, you need to create a timer of 60 seconds, and update time for every 60 seconds.

You need to do it like this:

NSTimer *timer = [NSTimer timerWithTimeInterval:60.0 target:self selector:@selector(updateTimer:)
                                                   userInfo:nil repeats:YES];
[[NSRunLoop mainRunLoop] addTimer:timer forMode:NSDefaultRunLoopMode];

- (void) updateTimer:(id) object
{
  // Write required code here.
}
