从其他目标获取Bundle ID [英] Get Bundle ID from a different target

问题描述

在我的Xcode项目中，我有4种不同的方案（prod，dev，staging，staging2），它们会更改安装到手机的应用程序的包标识符。这样我可以并排安装所有4个版本，类似于这种技术。

In my Xcode project, I have 4 different schemes (prod, dev, staging, staging2) which changes the bundle identifier of the app that gets installed to the phone. That way I can have all 4 versions installed side by side, similar to this technique.

现在我正在为iOS 8构建今日扩展这是一个需要自己的捆绑标识符的新Target。

Now I'm building a Today Extension for iOS 8. It's a new Target requiring its own bundle identifier.

扩展的捆绑标识符必须以Parent App的Bundle Identifier为前缀，否则会抛出警告：

The Extension's Bundle Identifier must be prefixed with the Parent App's Bundle Identifier, or a warning is thrown:

error: Embedded binary's bundle identifier is not prefixed with the parent app's bundle identifier.

    Embedded Binary Bundle Identifier:  com.company.app.TodayExtension
    Parent App Bundle Identifier:       com.company.app.staging

在这种情况下，嵌入式二进制包标识符必须是 com.company.app.staging.TodayExtension 。

In this case, the Embedded Binary Bundle Identifier must be com.company.app.staging.TodayExtension.

我有没有办法通过首先查看Parent目标的包标识符来配置我的Today Extension目标来设置其包标识符？也许通过自定义的运行脚本构建阶段？

Is there a way I can configure my Today Extension target to set its bundle identifier by first looking at the Parent target's bundle identifier? Perhaps through a custom Run Script Build Phase?

推荐答案

目标的构建设置不适用于其他目标。但是，可以使用PROJECT的构建设置。

The build settings of the targets are not available for the other targets. However the build settings of the PROJECT are available.

您可以在项目中添加用户定义的构建设置，并将其命名为PARENT_APP_BUNDLE_IDENTIFIER，并为所有方案设置正确的包ID。

You can thus add a user-defined build setting in your project and call it PARENT_APP_BUNDLE_IDENTIFIER and set the correct bundle id for all your schemes.

然后在应用扩展目标的信息标签中将捆绑ID设置为

Then in the info tab of the app extension target set the bundle id to

$(PARENT_APP_BUNDLE_IDENTIFIER).$(PRODUCT_NAME:rfc1034identifier)

它对我来说非常好。
