Appium [iOS] 仪器在启动时崩溃

Question

当 Appium 尝试运行应用程序时，屏幕闪烁并显示应用程序启动画面，就好像 Appium 多次尝试启动应用程序一样。这种行为在模拟器和真实设备上都会发生。

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

申请形式为.ipa

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).

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

Answer 2

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

您应该在创建 .ipa 时提供您的开发者身份...

如果您通过终端创建 ipa 文件，您可以按照给定的 link [博客]: Xcode "Build and Archive" from command line

Answer 3

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 Mac 运行 Xcode 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 4

如果您使用的是 iOS 模拟器，请执行以下操作...

在 Appium 中，转到 Developer Settings，检查 Custome Server Flags 并写入 --native-instruments-lib 在文本框中.

现在启动 Appium 服务器。

希望对您有所帮助！

Answer 5

就我而言，以下命令让我的生活变得一团糟：

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

所以不要将它添加到构建步骤中。

解决问题：重启设备 > 运行 Xcode > 连接设备 > 构建 & 运行应用程序 > 停止并退出 Xcode

现在验证在不使仪器崩溃的情况下启动应用程序。
