iOS开发中plist文件的创建与简单读取（一）

代码的下载地址http://download.csdn.net/detail/jingjingxujiayou/7198083

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)



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



4 。plist文件如下所示



5 如图所示类型为字典类型



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];

}
