Is it possible to refresh a timer in a Today Widget?

Question

I was wondering is it possible to update the text label of a timer in a today widget. I took a look around but nothing helped me.

Answer 1

I know this is a Swift question, but I found it looking for Objective-C code and so others may too.

-(void) viewDidLoad
{
    [NSTimer scheduledTimerWithTimeInterval:1 // update more than once a second to appear in sync with the system clock
                                     target:self
                                   selector:@selector(updateUi:)
                                   userInfo:nil
                                    repeats:YES];

}


-(void) updateUi:(NSTimer *)timer 
{
   // Update Widget UI as required
}
