仅在启用 debug 可执行文件时呈现共享选项才有效 - iOS - React Native

Question

在 React Native 应用程序中，共享功能是在 ios 本机中实现的。 UIDocumentInteraction 控制器用于显示共享窗口。

下面的代码被编写为 UIBarButton 的操作选择器。

@objc fileprivate func shareTapped(_ sender: UIBarButtonItem) {
    if let pageURL = extractPageFromDocument(document, forPageNumber: Int(pageIndex), withName: "share-report-page.pdf") {
      documentInteractionController.url = pageURL
      documentInteractionController.presentOptionsMenu(from: sender, animated: true)
    }
  }

当在 xcode 方案中启用调试可执行文件时，代码运行得非常好。

启用调试可执行文件后，此屏幕出现。

在 xcode 中禁用调试可执行文件的情况下运行应用程序时，相同的代码会产生崩溃。崩溃日志如下。

在崩溃之前尝试使用异常断点进行调试，调试器在“UIViewController+LayoutProtocol”的以下位置命中。

（https://i.sstatic.net/QG9FrjnZ.png）

这里的Self.presenter值是：

<SHSheetPresenter: 0x7fa3569125f0>

并且resolveOptions为零。

Answer 1

崩溃可能是由于无法识别的选定错误造成的，当在不支持该方法的对象上调用方法时，这种情况很常见。检查对标准控制器的扩展或修改，并确保所有对象都正确初始化。另外，确认与任何外部库的兼容性。
