如何在NSMenuItem中加载Xib文件？

Question

我想将Xib文件加载到NSMenu项目视图中，我具有带有带有标签的Xib的自定义视图类

@interface CustomItemView : NSView
@property (weak) IBOutlet NSTextField *Label1;
@property (weak) IBOutlet NSTextField *Label2;
@end

@implementation CustomItemView{

}

- (void)awakeFromNib {
    [super awakeFromNib];

}
- (void)drawRect:(NSRect)dirtyRect {
    [super drawRect:dirtyRect];

    // Drawing code here.
}

@end

我有一个要在其中加载以下菜单项的Menu Item类，是我要在其中加载自定义视图的菜单菜单Item类。我该怎么办？

@interface myMenuItem : NSMenuItem

@end

@implementation myMenuItem{
    CustomItemView *customItemView;

}

-(id)initWithDisplayDetails:(CGDirectDisplayID)display {
self = [super init];
    if (self) {
        customItemView = [[CustomItemView alloc] init];
        self.view = customItemView;
        self.target = self;
        self.action = @selector(changeCustomDisplayMode);

 }
    return self;

}

编辑：根据Willeke的建议，我已经实现了以下代码，并且对我有用。

-(id)initWithDisplayDetails:(CGDirectDisplayID)display {
self = [super init];
    if (self) {
          NSArray *nibObjects = [[NSArray alloc] init];
        [[NSBundle bundleForClass:[self class]] loadNibNamed:@"CustomItemView" owner:self topLevelObjects:&nibObjects];
        for (id topLevelObject in nibObjects) {
            if ([topLevelObject isKindOfClass:[NSView class]]){
                CustomItemView * customItemView = (CustomItemView *)topLevelObject;
                customItemView.label1.stringValue = @"1value"
                customItemView.label2.stringValue  = @"2value";
      self.view = customItemView;
            }
        }
        self.target = self;
        self.action = @selector(changeCustomDisplayMode);

 }
    return self;

}

最感激的帮助。
