DiskArbitration image Disk (dmg)

Question

Hello,

I have a problem using DiskArbitration framework, to catch disk image mounting I register for

DARegisterDiskMountApprovalCallback

The problem is that each time a disk image is mounted the callback is called twice.

Why is that and how can I solve this ?

Thanks.

Answer 1

I use these the catch that. I'm not sure of the difference these are to what you're doing but they work.

    [[[NSWorkspace sharedWorkspace] notificationCenter] addObserver:self selector:@selector(mediaMounted:) name:NSWorkspaceDidMountNotification object:[NSWorkspace sharedWorkspace]];
[[[NSWorkspace sharedWorkspace] notificationCenter] addObserver:self selector:@selector(mediaUnmounted:) name:NSWorkspaceWillUnmountNotification object:[NSWorkspace sharedWorkspace]];

Answer 2

Did you put a breakpoint in your callback to see what are the call-stack when it is called ? It can gives you some hints on what is going on.

Answer 3

I end up coding something to detect the 2nd mount and ignore it, thanks for your help people.
