更改NSPopover的外觀？

Question

我想做出NSPopover類似於此：

所以我想覆蓋圖。

不幸的是我沒有在Apple文檔中找到任何東西。

@interface NSPopoverFrame : NSView 
{ 
    const void *_themeX; 
    long long _popoverAppearance; 
    NSImage *_dragImage; 
    unsigned long long _anchorEdge; 
    struct CGSize _anchorSize; 
    CDStruct_3c058996 _contentInset; 
    struct CGPoint _anchorPoint; 
    unsigned long long _previousAnchorEdge; 
    struct CGPoint _previousAnchorPoint; 
    unsigned int _windowFilter; 
    struct { 
     unsigned int useDragWindowAppearance:1; 
     unsigned int hasActiveShadow:1; 
     unsigned int hasShadow:1; 
     unsigned int invalidateShadow:1; 
     unsigned int hasWindowBackgroundBlur:1; 
     unsigned int shouldBlurBackground:1; 
     unsigned int shouldInsetForAnchor:1; 
     unsigned int doingSolidFillHack:1; 
    } _flags; 
}

- (void)_commonPopoverInit; 

@end 

然後，我可以繼承_NSPopoverWindow，這也是私有的，並覆蓋

+ (Class)frameViewClassForStyleMask:(unsigned long long)arg1;

我不能繼承它，因爲： 不過，我使用類轉儲確實發現了下面的私有類它是私人的.. 有沒有辦法繞過這個？

或者還有其他方法嗎？

我發現在Github上這個偉大的倉庫：

不正是我一直在尋找。
