创建plist并写入

 

 1. 创建一个plist文件

 

    NSArray *paths=NSSearchPathForDirectoriesInDomains(NSDocumentDirectory,NSUserDomainMask,YES);  

    NSString *path=[paths    objectAtIndex:0];

    NSLog(@"path = %@",path);

    NSString *filename=[path stringByAppendingPathComponent:@"test.plist"];    //文件的完整路径

 

    NSFileManager* fm = [NSFileManager defaultManager];

    [fm createFileAtPath:filename contents:nil attributes:nil];      //根据完整路径创建文件  

 

    

2. 创建一个dic，写到plist文件里

    NSDictionary* dic = [NSDictionary dictionaryWithObjectsAndKeys:@"sina",@"1",@"163",@"2",nil];

    [dic writeToFile:filename atomically:YES];

    

3. 读文件内容

    NSDictionary* dic2 = [NSDictionary dictionaryWithContentsOfFile:filename];

    NSLog(@"dic is:%@",dic2);
