Answer 1

Use an NSTimer to trigger regular calls to a method that updates the label.

Answer 2

Ok. Here is something like you need.

Place an IBOutlet Label on your .h file of your view controller & connect in .xib file.

Now, just place following code in your .m file of view controller.

- (void)viewDidLoad
{
    [super viewDidLoad];
    // your label text is set to current time
    lblTime.text=[[NSDate date] description];
    // timer is set & will be triggered each second 
    [NSTimer scheduledTimerWithTimeInterval:1 target:self selector:@selector(showTime) userInfo:nil repeats:YES];

}
// following method will be called frequently.
-(void)showTime{
    lblTime.text=[[NSDate date] description];
}

If you have to format your date before showing it use the NSDateFormatter class.
