编译时出现ARC错误

Question

I'm trying to compile using the LLVM GCC 4.0 compiler, and I get this error in multiple of my .m files: ARC forbids explicit message send of 'release' I've tried using -fno-objc-arc as a compiler flag but that returns the error: Unrecognized command line option "-fno-objc-arc".

How can I solve this?

Answer 1

Simply remove all calls to -release . You're not allowed to call -release under ARC because the compiler will insert all the necessary retain / release calls for you. Read more about ARC here .

The other way is to use the conversion tool, and Xcode can convert your project to ARC (including removing these calls) for you:

To disable ARC entirely, change your build settings:

However I'd recommend you start using ARC, it will make things a lot easier and actually faster too.
