Authorization and removing folders
Hi all,
I need to remove a folder from within /Applications/OurCompany, so I'm
using Authorization Services to get Admin rights, and then using
removeFileAtPath to remove the folder.
When I'm logged on as admin, this works perfectly fine. When I'm logged
in as a standard user, I authenticate with the admin username and
password, authorization is granted ok, but then it still can't delete
the folder.
Can anybody suggest what I might be missing here? Perhaps I have
mis-understood the Apple security documentation?
Here is my code in case that may shed any light on this (strFolderPath
is declared earlier in the code)
// create the authorization reference...
AuthorizationRef myAuthorizationRef;
OSStatus myStatus;
myStatus = AuthorizationCreate (NULL,
kAuthorizationEmptyEnvironment, kAuthorizationFlagDefaults,
myAuthorizationRef);
AuthorizationItem myItems[1];
AuthorizationRights myRights;
myRights.items = myItems;
AuthorizationFlags myFlags = kAuthorizationFlagDefaults |
kAuthorizationFlagInteractionAllowed | kAuthorizationFlagExtendRights;
myItems[0].name = com.Test.myRight1;
myItems[0].valueLength = 0;
myItems[0].value = NULL;
myItems[0].flags = 0;
myRights.count = 1;
if (AuthorizationCopyRights (myAuthorizationRef, myRights,
kAuthorizationEmptyEnvironment, myFlags, NULL) ==
errAuthorizationSuccess)
{
panel = NSRunAlertPanel (@Test, @Got
Authorization!, @OK, nil, nil);
if ([NSFm removeFileAtPath: (NSString *)
strFolderPath handler: nil] == NO)
{
panel = NSRunAlertPanel (@Test,
@Folder NOT removed, @OK, nil, nil);
}
else
{
panel = NSRunAlertPanel (@Test,
@Folder removed, @OK, nil, nil);
}
}
else
{
panel = NSRunAlertPanel (@Test, @Not Got
Authorization!, @OK, nil, nil);
}

Finding files before app loads
Hi there, I need to locate certain files and set the state of some objects in my nib accordingly before the app is visible to the user. I'm using fileExistsAtPath to look for the files when the awakeFromNib method is invoked. The files are definitely present, but fileExistsAtPath always returns false on each search - please could someone advise where I might be going wrong?

Deleting Alias
Hi, I've tried using removeFileAtPath to delete an alias in the users home folder, but this doesn't work - it deletes any other file, just not aliases. I can't seem to find another method that will do the job. Any help or advice to resolve this would be greatly appreciated.

RE: Deleting Alias
Hi, just in case anybody else notices similar behaviour - I called removeFileAtPath if an fileExistsAtPath check on the alias evaluated to true - BUT fileExistsAtPath method only returns true on an alias if the original file / app is present. The removeFileAtPath method on its own will quite happily delete an alias whether the original file is present or not AFAIK. -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] om] On Behalf Of Glover,David Sent: 19 September 2008 11:36 To: Cocoa Development Subject: Deleting Alias Hi, I've tried using removeFileAtPath to delete an alias in the users home folder, but this doesn't work - it deletes any other file, just not aliases.

Removing folder from /Applications
Hi there, I've create a little app that is required to remove an obsolete folder from /Applications. This works fine when the user is logged in as an Admin, but not when logged in as a Standard user, as they obviously require authorization. So, I added some code to request an Admin username and password using Authorization Services, immediately before calling removeFileAtPath to remove the folder. However, the folder still cannot be removed after inputting an Admin username and password. Please can anybody offer any insight into what I'm missing here?

Requesting Administrator Name and Password
Hi all, I've created a little app that removes some files from within /Applications. This works fine when logged in as an Administrator, but won't run when logged in as a standard user.

Appending to file with writeToFile
Hi All, I'm using writeToFile to send strings to a log file at various points in my program, however it doesn't append the strings, it just overwrites the previous one. So the only thing in the log file is the very last string that was sent to it. I've searched around for a while and can't find any way to append the strings in my file. I was wondering if anyone else had achieved this? Or if anybody knows how to do it?
