pragma mark ARC和MRC混编
pragma mark 概念
/**
如果当前项目是 ARC项目
但是有非ARC的代码 则需要将文件编译成ARC代码
需要前往 项目 -->TARGETS Build Phases
设置 非ARC的文件 在Complie Sources(编译文件)
添加 -fno-objc-arc
*/
pragma mark 代码
#import <Foundation/Foundation.h>
#pragma mark 类
#pragma mark main函数
int main(int argc, const char * argv[])
{
// -fno-objc-arc
return 0;
}
Person.h //人类
#import <Foundation/Foundation.h>
@class Dog;
@interface Person : NSObject
@property (nonatomic, strong) Dog *dog;
@end
Person.m
#import "Person.h"
@implementation Person
@end
Dog.h //狗类
#import <Foundation/Foundation.h>
@class Bone;
@interface Dog : NSObject
@property(nonatomic, retain)Bone *bone;
@end
Dog.m
#import "Dog.h"
@implementation Dog
- (void)dealloc
{
[_bone release];
[super dealloc];
}
@end
Person.h //骨头类
#import <Foundation/Foundation.h>
@interface Bone : NSObject
@end
Person.m
#import "Bone.h"
@implementation Bone
- (void)dealloc
{
[super dealloc];
}
@end
