【问题描述】：

我有一个锁定屏幕的应用程序，现在我尝试使用多个屏幕。我不知道解锁第二个屏幕。这是我解锁第二个屏幕的方法：

if([[NSScreen screens] count] > 1){
    // Draw a new window to fill the screen
    NSScreen *screen;
    NSRect screenRect = CGRectMake(0, 0, screen.frame.size.width , screen.frame.size.height);

    NSWindow *secondaryMonitorWindow = [[NSWindow alloc] initWithContentRect:screenRect styleMask:NSBorderlessWindowMask  backing:NSBackingStoreBuffered  defer:NO  screen:screen];


    [secondaryMonitorWindow.contentView exitFullScreenModeWithOptions:nil];


}

如果有人可以帮助我，我成功解锁了第一个屏幕但不是第二个屏幕...

如果有人需要，我用以下代码修复它：

[windowArray insertObject:self.window atIndex:0];

        //if we have many screens
        NSRect screenRect;
        NSArray *screenArray = [NSScreen screens];
        for (NSInteger index = 1; index < [screenArray count]; index++)

        {

            NSScreen *screen = [screenArray objectAtIndex: index];

            screenRect = CGRectMake(0, 0, screen.frame.size.width , screen.frame.size.height);
            NSWindow *window = [[NSWindow alloc] initWithContentRect:screenRect styleMask:NSBorderlessWindowMask backing:NSBackingStoreBuffered defer:NO screen:screen];

            [window.contentView setWantsLayer:YES];
            window.contentView.layer.backgroundColor = [NSColor blackColor].CGColor;
            [window.contentView enterFullScreenMode:[[NSScreen screens] objectAtIndex:index] withOptions:nil];


            [windowArray addObject:window];

        }

不要忘记添加 .h

NSMutableArray *windowArray;

然后退出FullScreen：

for(NSInteger index = 1; index < [windowArray count]; index ++){

            if([[windowArray objectAtIndex:index]contentView].inFullScreenMode){

                [[[windowArray objectAtIndex:index]contentView] exitFullScreenModeWithOptions:nil];

            } 
        }
