无法直接在iPhone上运行本机应用程序（部署目标错误）

Question

问题

当我在Simulator中运行react-native时，它可以正常工作。我现在正在尝试在直接连接到MacBook的iPhone上运行它，但是出现了问题。 Deployment Target is set to 7.0有几条警告。

这是在哪里设置的？是在我正在使用的库中设置的吗？我该如何解决？

我发现与该问题似乎不重复的类似信息包括：

• 人们对模拟器有疑问（模拟器对我来说很好）
• 建议人们使用XCode中的Legacy Build系统（别人说这不是一个好主意）。

那么，到底是什么导致了此问题，我该如何解决该问题，以便可以在物理iPhone设备上运行该应用程序？

问题？

React Native似乎仅支持7.0的部署目标。但是，较新版本的XCode不再将7.0作为目标选项。新版本XCode的最低目标是8.0。

旧版构建？

我看到的一些问题说我可以改用Legacy Build。但是，我想知道这是否会引起任何其他问题。

Answer 1

我认为问题在于开发团队：

  

构建系统信息   错误：签署“ TestAppApp07Tests”需要开发团队。在项目编辑器中选择一个开发团队。 （在目标“ TestAppApp07Tests”中）

     

生成系统信息错误：签署“ TestAppApp07”需要输入   开发团队。在项目编辑器中选择一个开发团队。 （在   目标'TestAppApp07'）

只需成立一个有效的开发团队。如果您没有，请创建它。设置了正确的开发团队后，它应该可以工作。

确保为两个目标设置了团队：TestAppApp07和TestAppApp07Tests

关于部署目标：

如果与部署目标有关的问题与一些旧的依赖关系有关，我认为您可以使用旧版构建系统。

据我所知，Xcode 8或更高版本不支持部署目标iOS 7.0。

Answer 2

因此，该修复程序将需要设置您正在使用的设备版本的部署目标。

如果项目部署目标已设置为8，则无法在iOS 7或更低版​​本上运行它。确保您已经设置了要支持的最低部署目标。 可以在下面的窗口中设置。

Answer 3

尝试：

  

appc run -p ios -T设备

如果问题仍然存在，请尝试以下步骤

1. 从登录钥匙串中删除证书，然后尝试使用新创建的证书和供应配置文件。
2. 重新连接设备

很明显，您的部署目标设置为7.0，但Xcode支持从8.0开始。 设置部署目标。

1. 打开项目设置。
2. 选择目标 您的项目名称
3. 选择 常规
4. 转到 部署信息->部署目标器

如果仍然发现错误，请检查您的第三方框架是否存在兼容性问题。

请尝试避免使用旧版系统，因为设备可能会附带其他一些问题。
