Swift UIBarButtonItem标题

Question

@IBAction
func buttonTapped(_ sender: UIBarButtonItem) {
  guard let title = sender.currentTitle,
        let button = Buttons(rawValue: title) else { return }
}

我遇到的错误是“ UIBarButtonItem类型的值没有成员'currentTitle'，每个按钮都有枚举和大小写。

Answer 1

尝试gaurd let title = sender.title
