Overview

This class offers a high-level, Cocoa-style interface for DiskArbitration

VolumeManager offers similar functionality to the Disk Manager app or the diskutil command-line utility. It is possible to list all mounted volumes and manage both mounted and unmounted volumes or disks.

The delegate model is used to provide arbitration features to the delegate, allowing the delegate to approve or deny requests to mount or eject volumes. Additionally, the delegate’s notification methods are called when disks are pending mount, unmount, or eject, as well as after these events have taken place.

An example of these features is provided in the included “VolumeMgr” utility, which emulates the diskutil command-line utility.

To simply list all mounted volumes:

    VolumeManager *manager = [[VolumeManager alloc] init];
    NSArray *mounts = [manager mountedVolumes];

As documented below, it is possible to categorize mounted volumes by their “type” (bus or filesystem type). @see mountedVolumesByType and @see mountedVolumesForType:
