MWPhotoBrowser — A simple iOS photo browser

MWPhotoBrowser is an implementation of a photo browser similar to the native Photos app in iOS. It can display one or more images by providing either UIImage objects, file paths to images on the device, or URLs images online. Photos can also be zoomed and panned.

Usage

MWPhotoBrowser is designed to be presented within a navigation controller. You pass the browser an array of MWPhoto objects to display. You can create an MWPhoto object by providing a UIImage object, a file path to a physical image file, or a URL to an image.

See the code snippet below for an example of how to implement the photo browser. There is also a simple demo project within the project.

// Create array of `MWPhoto` objects
NSMutableArray *photos = [NSMutableArray array];
[photos addObject:[MWPhoto photoWithFilePath:[[NSBundle mainBundle] pathForResource:@"photo2l" ofType:@"jpg"]]];
[photos addObject:[MWPhoto photoWithURL:[NSURL URLWithString:@"http://farm4.static.flickr.com/3629/3339128908_7aecabc34b.jpg"]]];
[photos addObject:[MWPhoto photoWithURL:[NSURL URLWithString:@"http://farm4.static.flickr.com/3590/3329114220_5fbc5bc92b.jpg"]]];

// Create & present browser
MWPhotoBrowser *browser = [[MWPhotoBrowser alloc] initWithPhotos:photos];
[self.navigationController pushViewController:browser animated:YES];

If desired, you can choose which photo is displayed first:

// Create & present browser
MWPhotoBrowser *browser = [[MWPhotoBrowser alloc] initWithPhotos:photos];
[browser setInitialPageIndex:2]; // Show second page first
[self.navigationController pushViewController:browser animated:YES];

Adding to your project

1. Open MWPhotoBrowser.xcodeproj.
2. Drag the MWPhotoBrowser, Subclasses and Categories groups into your project, ensuring you check "Copy items into destination group's folder".
3. Copy the 4 UIBarButtonItemArrow*.png images and add them as resources to your bundle.
4. Import MWPhotoBrowser.h into your source as required.
