How to create an directory inside the documents directory of my iPhone app?

Question

I would like to store files in a specific directory inside the documents directory, so that I can iterate over all these files and show them to the user for selection. Is that possible?

Answer 1

Yes.

Use -[NSFileManager createDirectoryAtPath:withIntermediateDirectories:attributes:error:].

(The standard POSIX mkdir(2) also works.)

Answer 2

Yups,You can do it like:

NSString *rootString = [NSSearchPathForDirectoriesInDomains(NSDocumentDirectory,NSUserDomainMask,YES) objectAtIndex:0];
    self.root = [rootString stringByAppendingPathComponent:@"DirectoryName"];

    NSFileManager *fileManager = [NSFileManager defaultManager];
    if ([fileManager fileExistsAtPath:root isDirectory:YES] == NO)
    {
        [fileManager createDirectoryAtPath:root attributes:nil];
    }

And For retrieving you can do this:

NSError *error;

NSArray *files = [fileManager contentsOfDirectoryAtPath:root error:&error];

Hope this helps,
