[NSString stringWithCString:f encoding:NSUTF8StringEncoding]; 这个函数怎么hook

[wengxianxun]

CHDeclareClass(NSString)
#pragma clang diagnostic pop
CHOptimizedClassMethod2(self, id, NSString, stringWithCString, id ,arg,encoding,id,arg2){

id ss = CHSuper(2, NSString, stringWithCString,arg,encoding,arg2);

return ss;

}

这样写会闪退
