A trivial/lazy way do this is via some simple inline Applescript:

NSString *scriptAction = @"restart"; // @"restart"/@"shut down"/@"sleep"/@"log out"
NSString *scriptSource = [NSString stringWithFormat:@"tell application \"Finder\" to %@", scriptAction];
NSAppleScript *appleScript = [[NSAppleScript alloc] initWithSource:scriptSource];
NSDictionary *errDict = nil;
if (![appleScript executeAndReturnError:&errDict]) {
    NSLog(@"%@", errDict); 
}
