reac-native indirect_symbol_bindings[i] = cur->rebindings[j].replacement;
xcode 升级版本之后报错
错误信息
indirect_symbol_bindings[i] = cur->rebindings[j].replacement;
Thread 1: EXC_BAD_ACCESS (code=2, address=0x7fff865775c8)
解决办法
替换 node_modules/react-native/Libraries/fishhook 下的俩个文件 fishhook.c 和 fishhook.h
fishhook.c 替换 如下
