# castLabs DRMToday on iOS This article describes how to configure castLabs DRMToday with THEOplayer. Head to our page on [DRM](https://docs-preview.optiview.dolby.com/pr-863/theoplayer/how-to-guides/ios/drm/introduction.md) for more general information. ## Integration We provide open-source DRM integrations which are easy to maintain and allow for a modular approach. You can find them in the [DRM integration samples repository](https://github.com/THEOplayer/samples-drm-integration), alongside guides on how to integrate and use them. There currently is no ready-made integration for this DRM provider: you can choose to develop one based on the examples in the repository, or get in contact with us about making one. ## Code example Please refer to [DRM](https://docs-preview.optiview.dolby.com/pr-863/theoplayer/how-to-guides/ios/drm/introduction.md) (custom configuration). ## Resources *
