I use it in mac os x, as dyld_interposing does not works sometimes. I used it the hook a system api(LSOpenCFURLRef), but this symbol is lazy binding. And I cannot hook it successfully. Any idea? Thanks!

Yeah, this is an issue with fishhook. For that, I'd suggest checking out @landonf's PLPatchMaster — it does a lot more, but it includes hooking lazy/indirect symbols.
