ios - 应用程序在 UIActivityViewController 上呈现时崩溃

问题描述

当用户单击消息选项时，我的应用程序崩溃了。我正在使用下面的代码来显示活动视图。

 @IBAction func shareButtonAction(_ sender: Any) {
    let shareText = "Hello, world!"
    let vc = UIActivityViewController(activityItems: [shareText], applicationActivities: [])
    DispatchQueue.main.async {
       self.present(vc, animated: true)
    }
}
