Cocoa卸载驱动器但不弹出驱动器 [英] Cocoa Unmounting drive but not ejecting it

问题描述

您是否知道卸载驱动器而不弹出驱动器。 NSWorkspace 有一些方法来卸载驱动器，但它也弹出它们。

Do you know you to unmount a drive without ejecting it. NSWorkspace has some methods to unmount drives but it also eject them.

有什么想法吗？

推荐答案

我这样做，如下所示，它卸载驱动器，但不弹出。

（实际上我想弹出磁盘，我只能卸载磁盘。：P请分享如何弹出磁盘。）

I am doing it as follows and it un-mounts the drive but doesn't eject it.

(Actually I want to eject the disk, I can only un-mount the disk. :P Please share how to eject a disk.)

DASessionRef session = DASessionCreate(kCFAllocatorDefault);

CFURLRef path = CFURLCreateWithString(NULL, CFSTR("<path_to_your_volume_here>"), NULL);
DADiskRef disk = DADiskCreateFromVolumePath(kCFAllocatorDefault, session, path);

DADiskUnmount(disk, kDADiskUnmountOptionDefault, __unmountCallback, NULL);

这是我仍在使用的代码，正在开发和测试。

我手动创建路径。您可以使用（并共享）更好的方法以通用方式获取卷的路径。也许这个回答有正确的做法的提示。

我的更新，当我的发展完善和完整。

This is the code I am still working on and is under development and testing.
I am creating the "path" manually. You can use (and share) a better method to get the path of volume in a generic way. Perhaps this answer has hints of doing it the right way.

I'll update when my development is refined and complete.
