如何将Xcode项目转换为使用ARC(自动引用计数)? [英] How do I convert my Xcode project to use ARC (Automatic Reference Counting)?

问题描述

当我运行转换为Obj-C"时，它首先运行预检查".有些文件我希望Precheck忽略，我认为我可以在这些文件上设置编译器标志-fno-objc-arc.但是Precheck阶段似乎忽略了该标志(并将其重置)...所以我真的不知道如何超越Precheck.

When I run Convert to Obj-C it firsts runs a Precheck. Some files I want the Precheck to ignore, and I thought I could set the compiler flag -fno-objc-arc on those files. But Precheck phase seems to ignore that flag (and reset it)...so I don't really know how to get beyond Precheck.

推荐答案

预检查的第一步是列出所有文件，并在其前面加上复选框，只是取消粘贴那些您不想转换为ARC的文件，迁移工具将负责在转换过程中设置正确的编译器标志.

The first step of the pre-check has a list of all your files with checkboxes before them, just unstick the ones you do not want to convert to ARC, the migration tool will take care of setting the correct compiler flags during the conversion.
