Question

im kinda new to iOS.
I know that a void method i.e

-(void) pressed {

}

can be called this way:

[self pressed];

and viewDidAppear
can be called something like this:

[self viewDidAppear:YES];

I was wandering on how to do it in this method below, or how to re-Call it:

- (NSUInteger)numberOfItemsInCarousel:(iCarousel *)carousel
{

    return [images count];
}

Answer 1

That may me data source method… It is called from a controller.

//And it may be called in the controller as below where delegate is object of some class
    iCarousel *iCarouselObj;
    if(delegate && [delegate respondsToSelector:@selector(numberOfItemsInCarousel:)])
        int items = [delegate numberOfItemsInCarousel:iCarouselObj];

//The below code is just to tell you how to call a method with arguments
iCarousel *iCarouselObj;
int items = [self numberOfItemsInCarousel:iCarouselObj];
