objective-c - clang：错误：不能同时指定“-fobjc-arc”和“-fobjc-gc”

Question

我确实将Objective-C Automatic Reference Counting设置为YES，但我将 Objective-C Garbage Collection设置为Unsupported

所以我看不出如何设置 -fobjc-gc 。是否还有其他一些我没有注意到的设置？我已经尝试了一个干净的构建，所以它不会留下任何东西。

Answer 1

I found the answer, indirectly, thanks to this question. It turns out, that to get rid of garbage collection, I need to BOTH turn off garbage collection in the compiler settings when I click on Build Settings under the Project, and under the Target. If they disagree, the target (which is the one I didn't notice) overrides. No amount of playing with the settings at the project level was fixing that.
