objective-c - 使用 CGDisplay 显示窗口时，文本字段显示为不可编辑

Question

我正在制作一个应用程序，其中:

1. 当用户选择显示菜单选项时 -> 窗口将显示在整个屏幕上并且
2. 当用户选择隐藏菜单选项时 ->整个屏幕上可见的窗口将被隐藏。

问题是 -

When I am performing step 1 then step 2nd then step 1, the window does not appear as it appeared for the first time.

谁能建议我，我该如何解决它？

下面是部分代码:

- (IBAction)hideMenuAction:(id)sender
{   
    [window orderOut:nil];
    if (CGDisplayRelease( kCGDirectMainDisplay ) != kCGErrorSuccess) {
           NSLog( @"Couldn't release the main display!" );
        }
}

- (IBAction)displayMenuAction:(id)sender
{
    [window makeKeyAndOrderFront:nil];
        if (CGDisplayCapture( kCGDirectMainDisplay ) != kCGErrorSuccess) {
           NSLog( @"Couldn't capture the main display!" );
        }
    [window setLevel:CGShieldingWindowLevel()];
}

编辑:

当我放置代码行时，问题得到解决:[window makeKeyAndOrderFront:nil];在 displayMenuAction 中的 if block 下方。使用的代码是-

- (IBAction)displayMenuAction:(id)sender
{
     if (CGDisplayCapture( kCGDirectMainDisplay ) != kCGErrorSuccess) {
           NSLog( @"Couldn't capture the main display!" );
        }
    [window makeKeyAndOrderFront:nil];
    [window setLevel:CGShieldingWindowLevel()];
}

但是我开始面临一个新问题:

When I am performing step 1 then step 2nd then step 1, the text fields on window are appearing un-editable. I tried to set them as editable in code but it didn't work.

请提出建议。

窗口是在 Nib 中定义的吗？如果是这样，“关闭时释放”复选框是否处于事件状态？如果是，当窗口关闭时，它将被释放。
