1. 创建一个工程

2. 新建一个plist文件(command+N快捷键或者新建文件 如图下的红色圈)

![SouthEast][]

3. 红色圈是plist的文件名，这里默认为Property List，点击创建就可以了

![SouthEast 1][]

4 。plist文件如下所示

![SouthEast 2][]

5 如图所示类型为字典类型

![SouthEast 3][]

6 两个字典创建好了，注意这里给字典里添加数据时，要点击teacher的三角符号朝下时，点击“+”,这样才创建在字典里，不按照这样做，会在字典外面。

7 添加数据

8 plistde的文件创建好了，创建一个新的文件

studentViewController

studentViewController.m

- (void)viewDidLoad
    {
        [super viewDidLoad];
    	// Do any additional setup after loading the view.
        
        NSString* plistfile1 = [[NSBundle mainBundle]pathForResource:@"Property List" ofType:@"plist"];
        NSMutableDictionary* data = [[NSMutableDictionary alloc]initWithContentsOfFile:plistfile1];
        //打印出字典里的数据
        NSLog(@"%@",data);
        [data setObject:@"add some content" forKey:@"c_key"];
        
        //获取应用沙盒的Douch
        NSArray* paths = NSSearchPathForDirectoriesInDomains(NSDocumentationDirectory, NSUserDomainMask, YES);
        NSString* plist1 = [paths objectAtIndex:0];
        
        //获取一个plist文件
        NSString* filename = [plist1 stringByAppendingString:@"test.plist"];
        [data writeToFile:filename atomically:YES];
        NSMutableDictionary* data1 = [[NSMutableDictionary alloc]initWithContentsOfFile:filename];
        //打印出字典里的数据
        NSLog(@"%@",data1);
        
        //修改一个plist文件的数据
        [data1 setObject:@"要修改的数值" forKey:@"要修改的name"];
        [data1 writeToFile:filename atomically:YES];
    
        
        
    }

输出结果

2014-04-15 18:50:17.468 plistfile[1531:a0b] {
        student =     {
            Sname = lucy;
            Snum = 1;
        };
        teacher =     {
            Tname = jhon;
            Tnum = 2;
        };
    }
    2014-04-15 18:50:17.484 plistfile[1531:a0b] {
        "c_key" = "add some content";
        student =     {
            Sname = lucy;
            Snum = 1;
        };
        teacher =     {
            Tname = jhon;
            Tnum = 2;
        };
    }
