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.

Methods #

=(;, AssetTypeOptions, static, (, :) #

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.

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:

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