NatShare is a lightweight, easy-to-use native sharing API for Unity Engine. NatShare supports sharing text, images (using a Texture2D) and media files (using a string path). Currently, you can save media to the camera roll and open the native sharing UI:

To share an image, you can use the SharePayload:

Texture2D image = ...;
using (var payload = new SharePayload())
    payload.AddImage(image);

You can share multiple items at once:

using (var payload = new SharePayload()) {
    payload.AddText("Happy Birthday!");
    payload.AddMedia("/path/to/some/media/file.mp4");
}

Most payloads support a callback argument. This callback will be invoked when the user has finished the sharing activity:

using (var payload = new SharePayload(
    completionHandler: () => {
        Debug.Log("User shared video!");
    }
))
    payload.AddMedia("/path/to/some/media/file.mp4")

You can save images or media files to the camera roll with the SavePayload:

// Save a texture and a media file to the camera roll
Texture2D image = ...;
using (var payload = new SavePayload()) {
    payload.AddImage(image);
    payload.AddMedia("/path/to/some/media/file.gif");
}

After building an Xcode project from Unity, add the following keys to the Info.plist file with a good description:

• NSPhotoLibraryUsageDescription
• NSPhotoLibraryAddUsageDescription

• On Android, NatShare requires API Level 18+
• On iOS, NatShare requires iOS 9+
