Question

我一直试图解决我的问题2天，但我被封锁了。我使用了很多技术来追踪和发现我的错误。我无法解决最后一个问题。我无法向您展示我的应用程序（因为受保护的信息）但我可以向您显示我的日志：

当我点击按钮刷新我的输出完成。但是当我在不改变任何输入的情况下点击之后，应用程序就会停止。

非常感谢！

我通过在调用库之前在global.R脚本中添加此选项来解决我的问题：

@objc func getImage() {

    imagePicker.sourceType = UIImagePickerControllerSourceType.photoLibrary

    imagePicker.allowsEditing = false

    imagePicker.modalPresentationStyle = .overCurrentContext

    present(imagePicker, animated: true)

}

func imagePickerController(_ picker: UIImagePickerController, didFinishPickingMediaWithInfo info: [String : Any]) {

    if let image = info[UIImagePickerControllerOriginalImage] as? UIImage {
    imageView.image = image
 }

self.dismiss(animated: true, completion: nil);

}

使用“xlsx”包与问题相关联。

在shinyapp找不到错误
