objective c - AuthorizationExecuteWithPrivileges is deprecated

Question

Since updating to OSX 10.7 Lion, Xcode tells me that AuthorizationExecuteWithPrivileges is deprecated.

Can anyone suggest a way my application can write to a directory it doesn't have permission for?

Answer 1

I know it sounds crazy, but this actually works:

NSDictionary *error = [NSDictionary new]; 
NSString *script =  @"do shell script "whoami > /tmp/me" with administrator privileges";  
NSAppleScript *appleScript = [[NSAppleScript alloc] initWithSource:script]; 
if ([appleScript executeAndReturnError:&error]) {
  NSLog(@"success!"); 
} else {
  NSLog(@"failure!"); 
}

I'm executing an Applescript from Objective C. The only disadvantage is that you cannot gain permanent root privileges with this. It will ask for the password each time you run this.
