PhotoProgress: Using NSProgress
This sample demonstrates how to create and compose NSProgress objects, and show their progress in your app.
The app presents a collection view of photos, which will initially be placeholder images. Tap the "Import" button to import the album of photos, showing progress for each individual import as well as an overall progress. The import operation for each photo is composed of a faked "download" step followed by a filter step. Once the import of a photo finishes, the final image is displayed in the collection view cell.
Building this sample requires Xcode 7.0, iOS 9.0 SDK. This sample use new C# 6 features which means that you need IDE with C# 6 support(Xamarin Studio, Visual Studio 2015).
Running the sample requires iPhone/iPhoneSimulator with iOS 9.0 or later.
