CameraRoll

CameraRoll provides access to the local camera roll / gallery. Before using this you must link the RCTCameraRoll library. You can refer to Linking for help.

Permissions

The user's permission is required in order to access the Camera Roll on devices running iOS 10 or later. Add the NSPhotoLibraryUsageDescription key in your Info.plist with a string that describes how your app will use this data. This key will appear as Privacy - Photo Library Usage Description in Xcode.

saveToCameraRoll()

static saveToCameraRoll(tag, type?)

Saves the photo or video to the camera roll / gallery.

On Android, the tag must be a local image or video URI, such as "file:///sdcard/img.png".

On iOS, the tag can be any image URI (including local, remote asset-library and base64 data URIs) or a local video file URI (remote or data URIs are not supported for saving video at this time).

If the tag has a file extension of .mov or .mp4, it will be inferred as a video. Otherwise it will be treated as a photo. To override the automatic choice, you can pass an optional type parameter that must be one of 'photo' or 'video'.

Returns a Promise which will resolve with the new URI.

getPhotos()

static getPhotos(params)

Returns a Promise with photo identifier objects from the local camera roll of the device matching shape defined by getPhotosReturnChecker.

Expects a params object of the following shape:

  • first : {number} : The number of photos wanted in reverse order of the photo application (i.e. most recent first for SavedPhotos).
  • after : {string} : A cursor that matches page_info { end_cursor } returned from a previous call to getPhotos.
  • groupTypes : {string} : Specifies which group types to filter the results to. Valid values are:
    • Album
    • All
    • Event
    • Faces
    • Library
    • PhotoStream

    • Videos
    • Photos // default
  • mimeTypes : {string} : Filter by mimetype (e.g. image/jpeg).

Returns a Promise which when resolved will be of the following shape:

  • edges : {Array} An array of node objects
    • node: {object} An object with the following shape:
      • type: {string}
      • group_name: {string}
