如何在每次构建之前清理项目? [英] How to clean project before each build?

问题描述

在 Xcode 中是否有一种方法(可能使用方案)指定在进行新构建之前自动完成清理.?

Is there a way (possibly using schemes) in Xcode to specify that a clean is automatically done before doing a new build.?

我有一个项目，除非我先清理，否则有时无法构建，目前我正在手工完成.

I have a project that sometimes fails to build unless I do a clean first, currently I am doing it by hand.

推荐答案

按 ⌥⌘R，展开选定的方案，选择 Pre-actions，单击 +，选择 New Run Script Action，将 Provide Build Settings from 设置为您的目标.在下面的框中键入 rm -rf ${BUILT_PRODUCTS_DIR}.注意:在 Xcode 对话框中看到的是 BUILT 而不是 BUILD.您可以输入 echo ${BUILT_PRODUCTS_DIR} >~/Desktop/log.txt 看看要删除什么.

Press ⌥⌘R, expand the selected scheme, select Pre-actions, click +, select New Run Script Action, set Provide Build Settings from to your target. In the box below type rm -rf ${BUILT_PRODUCTS_DIR}. Note: it is BUILT not BUILD as seen in the Xcode dialog. You can type echo ${BUILT_PRODUCTS_DIR} > ~/Desktop/log.txt to see what's going to be deleted.
