Usage

Quick example

- (void)viewDidLoad
{
    [super viewDidLoad];
    _datasource = @[[UIImage imageNamed:@"test_1.jpg"],
                    [NSURL URLWithString:@"https://i.imgur.com/7jDvjyt.jpg"],
                    @"test_3.jpg"];

    _slideshow = [[KASlideShow alloc] initWithFrame:CGRectMake(0,0,320,250)];
    _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
    KASlideShowTransitionSlideVertical

You can furthermore specify the transition duration via setTransitionDuration.

Gestures

Two types gestures are available to interact with the slideshow via the addGesture method. It is possible to add them both.

    KASlideShowTransitionFade
    KASlideShowTransitionSlideHorizontal
    KASlideShowTransitionSlideVertical
