objective-c - Xcode全屏窗口没有标题栏

Question

我想创建一个全屏应用程序（mac），但即使我有全屏窗口； [window setFrame:[window frameRectForContentRect:[[window screen] frame]]display:YES animate:YES];

我无法摆脱标题栏？您可以更改上面的代码以使窗口没有标题栏，还是必须完全不同？谢谢 ：）

Answer 1

CocoaWithLove 有一篇关于它的好文章：

fullscreenWindow = [[FullscreenWindow alloc]
    initWithContentRect:[mainWindow contentRectForFrameRect:[mainWindow frame]]
    styleMask:NSBorderlessWindowMask
    backing:NSBackingStoreBuffered
    defer:YES
    screen:[mainWindow screen]];
[fullscreenWindow setLevel:NSFloatingWindowLevel];
[fullscreenWindow setContentView:[mainWindow contentView]];
[fullscreenWindow setTitle:[mainWindow title]];
[fullscreenWindow makeKeyAndOrderFront:nil];

Answer 2

我使用 window level 成功地将窗口放置在标题栏上NSScreenSaverWindowLevel，而不是NSFloatingWindowLevel在 Macmade 的回答中建议。

fullscreenWindow = [[NSWindow alloc]
                    initWithContentRect:[[NSScreen mainScreen] frame]
                    styleMask:NSBorderlessWindowMask
                    backing:NSBackingStoreBuffered
                    defer:YES];
[fullscreenWindow setLevel:NSScreenSaverWindowLevel];
// Perform further configuration here, e.g. setTitle, setBackgroundColor etc.
[fullscreenWindow makeKeyAndOrderFront:nil];
