OSX directory with spaces

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?

Answer 1

The -URLs method of of NSOpenPanel returns instances of NSURL , not file system paths. While NSURL s 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];

You could try removing the percent escapes in the directoryName string - I don't think the system needs them there. Something like:

directoryName = [directoryName stringByReplacingPercentEscapesUsingEncoding:NSUTF8StringEncoding];
