html 显示tableview,获取本地文件并显示在tableView中，如同QQ中的文件展示，但是还不能查看内容...

NSFileManager *fileManager = [NSFileManager defaultManager];

//在这里获取应用程序Documents文件夹里的文件及文件夹列表

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

NSString *docDir = [paths objectAtIndex:0];

//    NSLog(@"%@",docDir);

NSError *error = nil;

_dataFileArray = [[NSArray alloc] init];

//_dataFileArray便是包含有该文件夹下所有文件的文件名及文件夹名的数组

_dataFileArray = [fileManager contentsOfDirectoryAtPath:docDir error:&error];

//列出给定一个文件夹里的所有子文件夹名

NSMutableArray *dirArray = [[NSMutableArray alloc] init];

BOOL isDir = NO;

//在上面那段程序中获得的_dataFileArray中列出文件夹名

for (NSString *file in _dataFileArray) {

NSString *path = [docDir stringByAppendingPathComponent:file];

[fileManager fileExistsAtPath:path isDirectory:(&isDir)];

if (isDir) {

[dirArray addObject:file];

}
