不要等到明天，明天太遥远，今天就行动。

须读:看完该文章你能做什么？

如何将一个MRC的项目转成 ARC

学习前:你必须会什么?（在这里我已经默认你具备C语言的基础了）

什么是ARC，什么是MRC

一、本章笔记

   MRC 转 ARC 项目
    1.> Edit -> Convert -> To Objective-C ARC

二、code

main.m

#pragma mark 07-ARCתMRC
#pragma mark 概念
/*
    MRC 转 ARC 项目
    1.> Edit -> Convert -> To Objective-C ARC
 */
#pragma mark - 代码
#import <Foundation/Foundation.h>
#pragma mark 类
#import "Person.h"
#import "Dog.h"
#import "Bone.h"

#pragma mark - main函数
int main(int argc, const char * argv[])
{
    Person *p = [[Person alloc]init];
    Dog *d = [[Dog alloc]init];
    Bone *b = [[Bone alloc]init];
    

    return 0;
}

Person

>>>.h
#import <Foundation/Foundation.h>
@class Dog;
@interface Person : NSObject
@property (nonatomic, strong) Dog *dog;
@end
>>>.m
#import "Person.h"
#import "Dog.h"
@implementation Person

- (void)dealloc
{
     NSLog(@"%s",__func__);
}

@end

Dog

>>>.h
#import <Foundation/Foundation.h>
@class Bone;
@interface Dog : NSObject
@property(nonatomic, strong)Bone *bone;
@end
>>>.m
#import "Dog.h"
#import "Bone.h"
@implementation Dog

- (void)dealloc
{
    NSLog(@"%s",__func__);
     // Receiver type 'Bone' for instance message is a forward declaration
}
@end

Bone

>>>.h
#import <Foundation/Foundation.h>

@interface Bone : NSObject

@end

>>>.m
#import "Bone.h"

@implementation Bone
- (void)dealloc
{
     NSLog(@"%s",__func__);
}
@end
