Class AVExternalStorageDevice

  • All Implemented Interfaces:
    NSObject
    public class AVExternalStorageDevice
extends NSObject
    AVExternalStorageDevice An AVExternalStorageDevice represents a physical external storage device connected to the device that can be used to store captured media assets. Each instance of AVExternalStorageDevice corresponds to a physical external storage device where captured media assets can be stored. Instances of AVExternalStorageDevice cannot be created directly. An array of all currently available external storage devices can be obtained using AVExternalStorageDeviceDiscoverySession. Instances of AVExternalStorageDevice can be used with AVCaptureFileOutput subclasses for writing media files. API-Since: 17.0

        nextAvailableURLsWithPathExtensions:error: Next available security-scoped, DCF compliant URL array with different path extensions. Configures the folder structure (create a DCIM folder if there isn't one already) on the external storage device to provide the next available unique DCF compliant security-scoped URL array with different path extensions. Security-scoped URL requires the use of startAccessingSecurityScopedResource, and stopAccessingSecurityScopedResource for access. [nextAvailableURL startAccessingSecurityScopedResource]; . . . // your code to capture image / video . . . [nextAvailableURL stopAccessingSecurityScopedResource]; Use the +requestAccessWithCompletionHandler: method to request access to external storage device before getting the next available URL array else an error will be thrown.
        Parameters:
        extensionArray - An array of path extensions for the next available URL requested.
        outError - An out parameter with error information indicating why the URL could not be provided. If this method is successful, error will be nil.
        Returns:
        An array of DCF compliant security-scoped URL with all the path extensions requested.

      • requestAccessWithCompletionHandler

        public static void requestAccessWithCompletionHandler​(@NotNull
                                                      @NotNull AVExternalStorageDevice.Block_requestAccessWithCompletionHandler handler)
        requestAccessWithCompletionHandler: Requests access to capture onto an external storage device connected to this device, showing a dialog to the user if necessary. Use this method to request access to capture onto an external storage device connected to this device. This call will not block while the user is being asked for access, allowing the client to continue running. Until access has been granted, trying to capture into detected external storage devices will result in an error. The user is only asked for permission the first time the client requests access, later calls use the authorization status selected by the user. The completion handler is called on an arbitrary dispatch queue. It is the client's responsibility to ensure that any UIKit-related updates are called on the main queue or main thread as a result.
        Parameters:
        handler - A completion handler block called with the result of requesting access to capture onto an external storage device.
