拷贝内容到剪贴板

let content = "hello world"
let pb = NSPasteboard.general()
pb.clearContents()
pb.writeObjects([content as NSString])

从剪贴板读取内容

let pb = NSPasteboard.general()
let content = pb.readObjects(forClasses: [NSString.self], options: nil)

使用NSPasteboardItem

for item in pb.pasteboardItems ?? [] {
    if let str = item.string(forType: kPublicUrl) {
        textView.string = "url: \(str)"
    } else if let str = item.string(forType: kPublicUrlName) {
        textView.string = "url name: \(str)"
    } else {
        let str = item.string(forType: NSPasteboardTypeString)
        textView.string = str
    }
}

NSPasteboardItem使用UTI来获取剪贴板内容，NSPasteboardTypeString就是一种UTI，Chrome浏览器中地址栏复制到剪贴板后，其UTI为public.url
