如何存储.plist文件中解析的JSON？

Question

我JSON文件是这样的：

{"fileContent":[{"name":"aaaa","type":"file","ext":"sql","modified":"2013\/04\/11 - 04:29","created":"2013\/04\/11 - 04:29","size":"1460","dirid":"5"}, {"name":"directory02","type":"file","ext":"sql","modified":"2013\/04\/11 - 04:29","created":"2013\/04\/11 - 04:29","size":"1577","dirid":"6"}, {"name":"index2","type":"file","ext":"php","modified":"2013\/04\/11 - 05:06","created":"2013\/04\/11 - 05:06","size":"9932","dirid":"8"}, {"name":"directorffdsgfg","type":"file","ext":"sql","modified":"2013\/04\/11 - 10:00","created":"2013\/04\/11 - 10:00","size":"1577","dirid":"10"}, {"name":"directory02","type":"file","ext":"sql","modified":"2013\/04\/11 - 12:10","created":"2013\/04\/11 - 12:10","size":"1577","dirid":"11"},{"name":"jquery- mousewheel-master","type":"file","ext":"zip","modified":"2013\/04\/11 - 12:10","created":"2013\/04\/11 - 12:10","size":"5213","dirid":"12"},{"name":"perfect-scrollbar-master","type":"file","ext":"zip","modified":"2013\/04\/11 - 12:10","created":"2013\/04\/11 - 12:10","size":"11867","dirid":"13"}, {"name":"E_PDF","type":"file","ext":"png","modified":"2013\/04\/17 - 09:15","created":"2013\/04\/17 - 09:15","size":"7467","dirid":"24"}, {"name":"filefolder_H.PNG","type":"file","ext":"png","modified":"2013\/04\/17 - 09:15","created":"2013\/04\/17 - 09:15","size":"10575","dirid":"25"}],"folderContent": [{"name":"Folder 2","type":"folder","ext":"sql","modified":"2013\/04\/11 - 05:04","created":"2013\/04\/11 - 05:04","size":"1577","dirid":"7"},{"name":"Folder 1","type":"folder","ext":"zip","modified":"2013\/04\/15 - 09:08","created":"2013\/04\/15 - 09:08","size":"11867","dirid":"14"}],"files":9,"folders":2} 

和NSDictionary与名称的标题存储此。 （下代码显示它：）

NSDictionary *titles = [NSJSONSerialization JSONObjectWithData:Data options:kNilOptions error:nil]; 

，我读标题fileContent价值和他们的NSMutableArray存储与名为“所有”这样的代码：

NSArray *fileContent = [titles objectForKey:@"fileContent"]; 
NSMutableArray *all = [[NSMutableArray alloc]init]; 
[all addObjectsFromArray:fileContent]; 

我想店2值（名称&类型）从“所有”.plist文件，但我不知道它是如何做到的？

尝试

NSDictionary *titles = [NSJSONSerialization JSONObjectWithData:Data options:kNilOptions error:nil]; 

NSArray *fileContent = [titles objectForKey:@"fileContent"]; 
NSMutableArray *all = [fileContent mutableCopy]; 

NSMutableArray *folders = [NSMutableArray array]; 
[all enumerateObjectsUsingBlock:^(id obj, NSUInteger idx, BOOL *stop) { 
    NSDictionary *folder = (NSDictionary *)obj; 

    NSMutableDictionary *dict = [NSMutableDictionary dictionary]; 
    [dict setObject:folder[@"name"] forKey:@"name"]; 
    [dict setObject:folder[@"type"] forKey:@"type"]; 

    [folders addObject:dict]; 

}]; 

NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES); 
NSString *documentsDirectory = paths[0]; 
NSString *filePath = [documentsDirectory stringByAppendingPathComponent:@"Folders.plist"]; 

[folders writeToFile:filePath atomically:YES];
