    _slideshow.datasource = self;
    _slideshow.delegate = self;
    [_slideshow setDelay:3]; // Delay between transitions
    [_slideshow setTransitionDuration:1]; // Transition duration
    [_slideshow setTransitionType:KASlideShowTransitionFade]; // Choose a transition type 
    [_slideshow setImagesContentMode:UIViewContentModeScaleAspectFill]; // Choose a content mode for images to display
    [_slideshow addGesture:KASlideShowGestureTap]; // Gesture to go previous/next directly on the image
}

#pragma mark - KASlideShow datasource

- (NSObject *)slideShow:(KASlideShow *)slideShow objectAtIndex:(NSUInteger)index
{
    return _datasource[index];
}

- (NSUInteger)slideShowImagesNumber:(KASlideShow *)slideShow
{
    return _datasource.count;
}

#pragma mark - KASlideShow delegate

- (void) slideShowWillShowNext:(KASlideShow *)slideShow
{
    NSLog(@"slideShowWillShowNext, index : %@",@(slideShow.currentIndex));

KASlideShowDataSource

You need to implement the datasource to display images. KASlideShow can handle UIImage, NNString (name of local image) and NSURL (URL of remote image).

- (NSObject *) slideShow:(KASlideShow *)slideShow objectAtIndex:(NSUInteger)index;
- (NSUInteger) slideShowImagesNumber:(KASlideShow *)slideShow;

Use of a slideshow

[_slideshow next]; // Go to the next image
[_slideshow previous]; // Got to the previous image
[_slideshow start]; // Start automatic slideshow
[_slideshow stop]; // Stop automatic slideshow

KASlideShowDelegate

- (void) slideShowDidShowNext:(KASlideShow *) slideShow;
- (void) slideShowDidShowPrevious:(KASlideShow *) slideShow;
- (void) slideShowWillShowNext:(KASlideShow *) slideShow;
- (void) slideShowWillShowPrevious:(KASlideShow *) slideShow;
- (void) slideShowDidSwipeLeft:(KASlideShow *) slideShow;
- (void) slideShowDidSwipeRight:(KASlideShow *) slideShow;

Transitions

Here are the 3 available types of transitions you can set via setTransitionType.

    KASlideShowTransitionFade
    KASlideShowTransitionSlideHorizontal
