Reload the view in iphone (in viewWillAppear)

I got a little app that has a button whose click is handled via

- (IBAction)click:(id)sender { }

Now, what I want is after click() runs, I want the view to refresh/reload itself, so that viewWillAppear() is re-called automatically. Basically how the view originally appears.

Of course I can call viewWillAppear manually, but was wondering if I can get the framework to do it for me?

viewWillAppear is where to put code for when your view will appear, so it is more appropriate to put code that will be called repeatedly into another method like -resetView, which can then be called by both viewWillAppear and your click method. You can then call setNeedsDisplay from within resetView.

-(void)resetView
{
    //reset your view components.
    [self.view setNeedsDisplay];
}

-(void)viewWillAppear
{
    [self resetView];
}


- (IBAction)click:(id)sender
{
    [self resetView];
}
