我创建了一个“首选项窗格”项目。在这个项目中，我想从我的 bundles 资源文件夹中加载一个图像。这似乎很困难，因为“[NSBundle mainBundle]”似乎返回以下内容：

27/12/10 9:24:18 PM System Preferences[5076]    NSBundle </Applications/System Preferences.app> (loaded)

遍历“[NSBundle allBundles]”显示我的项目包出现了，但似乎没有被加载：

我不确定这里发生了什么。如何访问我的 prefpane 包？

在你的主类中调用[self bundle]应该这样做。

我认为你必须使用“[NSBundle bundleForClass:[self class]];”。

迟到的答案，但对于寻找完整解决方案的人来说。如果您的 prefPane 包中有一个名为的图像资源，您red.png可以通过调用以下命令来加载该资源：

NSImage *redIndicator = [[self bundle] imageForResource:@"red"];
