Question

I’m having an issue with opening directories that have spaces in them. My code looks like this:

NSOpenPanel* openDlg = [NSOpenPanel openPanel];

[openDlg setCanChooseDirectories:YES];
if ( [openDlg runModal] == NSOKButton )
{

    NSArray* files = [openDlg URLs];

        NSString* directoryName = [[files objectAtIndex:0] absoluteString];
    directoryURL = [files objectAtIndex:0];
        NSLog(@"Directory Name: %@", directoryName);


        NSArray *directoryArray = [directoryName componentsSeparatedByString:@"/"];


    NSString* currentDirectory = [directoryArray objectAtIndex:(directoryArray.count- 2)];

    [directoryBox setTitle:currentDirectory];
}

When I select a directory name with spaces the files are not displayed in a table and the output in the NSLog looks like this:

Directory Name:

file://localhost/Users/Rich/Software%20Bisque/

Any ideas?

The -URLs method of of NSOpenPanel returns instances of NSURL, not file system paths. While NSURLs have become the preferred way to refer to files, you can easily change to a file system path by using NSURL‘s -path method.

Note that there are many methods specific to working with file system paths that are added to NSString in NSPathUtilities.h. You could probably rewrite your code to incorporate those (double-check that I’ve got your targeted directory okay):

NSArray* files = [openDlg URLs];

NSString* directoryName = [[files objectAtIndex:0] path];
directoryURL = [files objectAtIndex:0];
NSLog(@"Directory Name: %@", directoryName);

// NSArray *directoryArray = [directoryName pathComponents];

// NSString* currentDirectory = [directoryArray objectAtIndex:(directoryArray.count- 2)];

NSString *currentDirectory = [[directoryName stringByDeletingLastPathComponent]
                                    lastPathComponent];

[directoryBox setTitle:currentDirectory];
