Appium [iOS] 仪器在启动时崩溃

Question

也许有人可以帮助我。

当 appium 尝试运行应用程序时，屏幕会闪烁应用程序启动画面，就像 appium 尝试多次启动应用程序一样。这种行为在模拟器和真实设备上都会发生。

我在我的 iOS 设备 UI 自动化上设置了启用，但是当我尝试启动检查器时，我遇到了这个问题：

应用程序的格式为 .ipa

谢谢， 最好的问候。

Answer 1

Target failed to run: Permission to debug com.myapp.iphone was denied. 
The app must be signed with a development identity (e.g. iOS Developer).

您的应用程序应使用开发人员密钥进行签名。 Click here for documentation

Answer 2

如果您使用的是 iOS 模拟器，请执行以下操作...

在Appium中，进入Developer Settings，勾选Custome Server Flags并写入--native-instruments-lib 在文本框中。

现在启动 Appium 服务器。

希望这会有所帮助！

Answer 3

BlockquoteTarget 运行失败：调试 com.myapp.iphone 的权限被拒绝。 该应用程序必须使用开发身份（例如 iOS 开发人员）进行签名。 块引用

您应该在创建 .ipa 时提供您的开发者身份...

如果你是通过终端创建 ipa 文件，你可以点击给定的链接 [博客]：Xcode "Build and Archive" from command line

Answer 4

我也遇到过这个问题，发现你需要在你的iDevice的开发者选项中启用UI自动化

如何启用 UI 自动化 1.关闭iDevice， 2.然后连接到运行Xcode的Mac 3.在将其重新打开以显示开发人员选项之前。 4. 点击开发者选项并启用 UI 自动化

Answer 5

在我的例子中，以下命令让我的生活陷入困境：

rm -rf $HOME/Library/Developer/Xcode/iOS\ DeviceSupport/*

所以不要将它添加到构建步骤中。

要解决此问题： 重启设备 > 运行 Xcode > 连接设备 > 构建并运行应用程序 > 停止并退出 Xcode

现在验证启动应用程序不会导致仪器崩溃。
