查看ARC在何处插入保留和释放 [英] Seeing where ARC is inserting retain and releases

问题描述

是否有编译器选项(或其他某种方式)来查看ARC在何处插入保留和释放?这主要是出于好奇.我可以在反汇编代码中看到它们，但这有时很难理解.

Is there a compiler option (or some other way) to see where ARC is inserting retain and releases? This is mostly out of curiosity. I can see them in the disassembly code, but that's hard to wade through sometimes.

推荐答案

否.如果编译器提供了此功能，那么保留/释放的数量绝对会让您不知所措，因为其中大多数是在优化阶段删除的.但是编译器甚至无法做到这一点，因为ARC并不是预处理阶段.它是编译的一部分.因此，除了查看程序集之外，您将一无所获.

No. If the compiler were to provide this, you'd get absolutely overwhelmed by the number of retains/releases, since most of them are taken out during the optimization stage. But the compiler can't even do that, because ARC isn't a pre-processing stage. It's part of the compilation. So you're not going to be able to get anything besides looking at the assembly.
