xcode 支持 object-c 混编,在object-c 中调用c,c++接口
第一步 定义c语言 接口(File.c)
#include <stdio.h>void printsByC(){printf("调用C语言。");}
第二步 定义c++ 接口
student.h文件
#ifndef __test_hun__student__#define __test_hun__student__#include <iostream>#endif /* defined(__test_hun__student__) */
student.cpp文件
#include "student.h"using namespace std;class Student{public:void getWeight(){cout<<"Object C与C++混合编程。体重为:"<<weight<<"kg";printf("调用C++语言。getWeight");}void setWeight(int x){weight = x;printf("调用C++语言。setWeigth");}private:int weight;};
第三步 将 object-c implementation文件名 .m 改称.mm 告诉编译器 混编
下面的例子是 object-c 调用接口
- (void)viewDidLoad{[super viewDidLoad];// Do any additional setup after loading the view, typically from a nib.printf("调用C语言。");Human human;human.setWeight(26);human.getWeight();Student *student=new Student();student->getWeight();delete student;}
