单击鼠标时可可检测对象

Question

我创建了一个自定义对象（NSImageView）来显示图像，我使用addSubview：self.view来添加 我想确定鼠标是否单击它。 我该怎么办？

谢谢。

NSImage *Image = [NSImage imageNamed:@"oneimage.jpg"];
NSImageView *ImageView = [[NSImageView alloc] init];
[ImageView setImage:Image];
[self.window addSubview:ImageView];
[ImageView_IconToAdd setAcceptsTouchEvents:YES];
[ImageView_IconToAdd setWantsRestingTouches:YES];


-(void)mouseDragged:(NSEvent *)theEvent {
    id clickedObject = [self hitTest:[theEvent locationInWindow]];
    if ([clickedObject isKindOfClass:[NSImageView class]]) {
        NSLog(@"Clicked an ImageView");
    } else if ([clickedObject isKindOfClass:[NSView class]]) {
        NSLog(@"Clicked a WebView");
    }
}

但错误：

No visible @interface for 'WindowImage' declares the selector 'hitTest:'

并且无法获得对象！
