Runtime使ViewController具有name属性

demo下载 http://download.csdn.net/detail/xlsn0w/9429187

写一个分类 在.h文件里面定义属性

#import <Foundation/Foundation.h>

@interface NSObject (Name)

@property (nonatomic,strong)NSString *name;

@end

在.m里面重写set get方法

#import "NSObject+Name.h"

#import <objc/objc-runtime.h>

@implementation NSObject (Name)

const void *key;

- (void)setName:(NSString *)name {

    

    objc_setAssociatedObject(self,key, name,OBJC_ASSOCIATION_COPY_NONATOMIC);

    

}

- (NSString *)name {

    

    returnobjc_getAssociatedObject(self,key);

}

然后在

ViewController里面就能通过点语法 点出name属性

#import "NSObject+Name.h"

#import <objc/objc-runtime.h>

@interface ViewController ()

@end

@implementation ViewController

- (void)viewDidLoad {

    [superviewDidLoad];

    // Do any additional setup after loading the view, typically from a nib.

    

    

    self.name =@"runtime使ViewController具有name属性";

    NSLog(@"%@",self.name);

}

@end
