给类添加方法_skybeauty_新浪博客

#import

@interface Stuent : NSObject

{

   int age;

   NSString * name;

}

@property int age;

@property(nonatomic,retain) NSString * name;

//-(void)print;

@end

#import "Stuent.h"

@implementation Stuent

@synthesize age;

@synthesize name;

 

@end

下面是给类添加新方法

#import "Stuent.h"

@interface Stuent (New)

-(void)info;

@end

#import "Stuent+New.h"

@implementation Stuent (New)

-(void)info

{

    NSLog(@"%@,%d",name,age);;

}

@end

#import

#import "Stuent.h"

#import "Stuent+New.h"

int main(int argc, const char * argv[])

{

    @autoreleasepool {

        

        // insert code here...

        NSAutoreleasePool * pool = [[NSAutoreleasePool alloc] init];

       Stuent * student = [[Stuent alloc] init];

        student.name = @"lilei";

        student.age = 24;

        //[student print];

        NSLog(@"Hello, World!");

        [student info];

        [student release];

        [pool drain];

        

    }

   return 0;

}
