我将如何编码：选择 titlelabel.text 等于“类别”的按钮

@IBOutlet var buttons: [UIButton]!

var category: String?

  override func viewDidLoad() {

这是您如何filter退出该按钮的方法

let requiredButton = buttons
        .filter{ $0.titleLabel?.text == "category" }.first

你也可以通过first

let butt =   buttons.first(where: { $0.titleLabel?.text == "category" })
