我的OS X应用程序如何接受从Cocoa桌面拖放图片文件？

class MyView: NSView {
    override func awakeFromNib() {
        super.awakeFromNib()
        registerForDraggedTypes([NSFilenamesPboardType])
    }
    
    override func draggingEntered(sender: NSDraggingInfo) -> NSDragOperation {
        if sender.draggingPasteboard().types?.contains(NSFilenamesPboardType) ?? false {
            return .copy
        }
        return []
    }
    
    override func performDragOperation(sender: NSDraggingInfo) -> Bool {
        let pasteboard = sender.draggingPasteboard()
        if let fileURLs = pasteboard.propertyList(forType: NSFilenamesPboardType) as? [String] {
            for fileURL in fileURLs {
                // 处理文件路径，例如加载图片、显示图片等
            }
            return true
        }
        return false
    }
}
