Answer 1

evanchin is correct. Further more, if you want to do this in Xamarin.iOS (aka monotouch):

var lib = new ALAssetsLibrary();
lib.Enumerate(ALAssetsGroupType.All, (ALAssetsGroup group, ref bool libStop) =>
{
    if (group == null)
    {
        return;
    }
    group.Enumerate((ALAsset asset, int index, ref bool groupStop) =>
    {
        if (asset != null && asset.Editable)
        {
            asset.SetImageDataAsync(new NSData(IntPtr.Zero), new NSDictionary(IntPtr.Zero));
        }
    });
}, error => { });

This code will delete all images that your app added to the ALAssetsLibrary.
