创建文件夹：

NSString *Dir = [NSString stringWithFormat:@"%@/%@", NSHomeDirectory(), dirName];BOOL isDir = NO;NSFileManager *fileManager = [NSFileManager defaultManager];BOOL existed = [fileManager fileExistsAtPath:Dir isDirectory:&isDir];if ( !(isDir == YES && existed == YES) ){[fileManager createDirectoryAtPath:imageDir withIntermediateDirectories:YES attributes:nilerror:nil];}

删除文件夹和文件级内的文件：

NSString *Dir = [NSString stringWithFormat:@"%@/%@", NSHomeDirectory(), dirName];NSFileManager *fileManager = [NSFileManager defaultManager];[fileManager removeItemAtPath:Dir error:nil];
