NZAssetsLibrary is a ALAssetsLibrary extension. This class save, delete and load images from specific album or device folder.

Build Status

Requirements

NZAssetsLibrary works on iOS 5.0+ and is compatible with ARC projects. It depends on the following Apple frameworks, which should already be included with most Xcode templates:

  • AssetsLibrary.framework
  • Foundation.framework

You will need LLVM 3.0 or later in order to build NZAssetsLibrary.

To build the sample is necessary iOS 6+ (sample project use UICollectionViewController class). The sample project uses AGPhotoBrowser.

Adding NZAssetsLibrary to your project

Source files

Alternatively you can directly add source files to your project.

  1. Download the latest code version or add the repository as a git submodule to your git-tracked project.
  2. Open your project in Xcode, then drag and drop all files at NZAssetsLibrary folder onto your project (use the "Product Navigator view"). Make sure to select Copy items when asked if you extracted the code archive outside of your project.

    if (error) {
        NSLog(@"Failed to save image.");
        return;
    }

    NSLog(@"Image saved successfully.");

        NSLog(@"Could not load images.");
        return;
    }
