Question

I have the following code:

NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
NSString *documentsDirectory = [paths objectAtIndex:0];

However I am clueless as to how to get all the files names and assign them to an array?

Any help would be appreciated.

NSFileManager has a method called contentsOfDirectoryAtPath:error: that returns an array of all the files in that directory.

You can use it like this:

NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
if([paths count] > 0)
{
    NSString *documentsDirectory = [paths objectAtIndex:0];
    NSError *error = nil;
    NSArray *documentArray = [[NSFileManager defaultManager] contentsOfDirectoryAtPath:documentsDirectory error:&error];
    if(error)
    {
        NSLog(@"Could not get list of documents in directory, error = %@",error);
    }
}

The documentsArray object will contain a list of all the files in that directory.
