NSWindow全屏显示，但显示码头

Question

现在我终于设法通过http://cocoadevcentral.com/articles/000028.php 创建一个全屏窗口辉煌的教程。现在问题如何使用下面的代码来显示码头和菜单栏，因为目前我有一个完全黑屏，我想看到一个菜单栏和一个码头。那可能吗？

- (void)applicationDidFinishLaunching:(NSNotification *)notification 
{ 
    int windowLevel; 
    NSRect screenRect; 
    // Capture the main display 
    if (CGDisplayCapture(kCGDirectMainDisplay) != kCGErrorSuccess) { 
     NSLog(@"Couldn't capture the main display!"); 
     // Note: you'll probably want to display a proper error dialog here 
    } 
    // Get the shielding window level 
    windowLevel = CGShieldingWindowLevel(); 
    // Get the screen rect of our main display 
    screenRect = [[NSScreen mainScreen] frame]; 
    // Put up a new window 
    mainWindow = [[NSWindow alloc] initWithContentRect:screenRect 
            styleMask:NSBorderlessWindowMask 
            backing:NSBackingStoreBuffered 
            defer:NO screen:[NSScreen mainScreen]]; 
    [mainWindow setLevel:windowLevel]; 
    [mainWindow setBackgroundColor:[NSColor blackColor]]; 
    [mainWindow makeKeyAndOrderFront:nil]; 
    // Load our content view 
    [slideShowPanel setFrame:screenRect display:YES]; 
    [mainWindow setContentView:[slideShowPanel contentView]]; 
}

花了一些尝试，但我想通了;

- (void)applicationDidFinishLaunching:(NSNotification *)notification 
{ 
int windowLevel; 
NSRect screenRect; 
// Capture the main display 

// Get the screen rect of our main display 
screenRect = [[NSScreen mainScreen] frame]; 
// Put up a new window 
mainWindow = [[NSWindow alloc] initWithContentRect:screenRect 
             styleMask:NSBorderlessWindowMask 
              backing:NSBackingStoreBuffered 
              defer:NO screen:[NSScreen mainScreen]]; 
[mainWindow setLevel:windowLevel]; 
[mainWindow setBackgroundColor:[NSColor blackColor]]; 
[mainWindow makeKeyAndOrderFront:nil]; 
// Load our content view 
[slideShowPanel setFrame:screenRect display:YES]; 
[mainWindow setContentView:[slideShowPanel contentView]]; 

}
