XKPhotoScrollView

[](https://travis-ci.org/Karl von Randow/XKPhotoScrollView)

Usage

The XKPhotoScrollView is a UIView subclass which provides a swipeable and zoomable photo viewer, modelled on the iOS Photos app. It uses a delegate and dataSource approach to notifying your code about events, and for obtaining views containing photos (or whatever you want to present).

The examples project contains a number of examples, showing how you can use the XKPhotoScrollView with Interface Builder, or in code, with or without Auto Layout. The examples also show how it can rotate with your view controller, if you view controller supports auto rotation. Or you can monitor UIDevice for orientation events and tell XKPhotoScrollView to change its orientation internally, so your view controller isn't required to rotate.

To run the example project, clone the repo, and run pod install from the Example directory first.

Here is a short example of integrating XKPhotoScrollView based on the Manual example:

- (void)loadView
{
    XKPhotoScrollView *photoScrollView = [XKPhotoScrollView new];
    photoScrollView.dataSource = self;
    photoScrollView.delegate = self;

    self.view = photoScrollView;
}

#pragma mark - XKPhotoScrollView

#pragma mark XKPhotoScrollViewDataSource

- (void)photoScrollView:(XKPhotoScrollView *)photoScrollView requestViewAtIndexPath:(NSIndexPath *)indexPath
{
    UIImage *image = _images[indexPath.col];
    UIImageView *view = [[UIImageView alloc] initWithImage:image];

    [photoScrollView setView:view atIndexPath:indexPath placeholder:NO];
}

- (NSUInteger)photoScrollViewCols:(XKPhotoScrollView *)photoScrollView
{
    return _images.count;
}

#pragma mark XKPhotoScrollViewDelegate

- (void)photoScrollView:(XKPhotoScrollView *)photoScrollView didTapView:(UIView *)view atPoint:(CGPoint)pt atIndexPath:(NSIndexPath *)indexPath
{
    NSInteger col = indexPath.col;
}

Features

• Supports asynchronous delivery of views, including placeholder vs final views
• Minimum and maximum zoom scales and zoom bounce options
• Rich delegate events
