NSOpenPanel - Set file type?

Question

Just looking on what I would use to only allow specific files to be selected (Images for now)

setFileTypesArray returns

NSOpenPanel may not respond to -setFileTypesArray:

and then the panel doesn't open up at all. Heres my code:

    NSArray  * fileTypes = [NSArray arrayWithObjects:@"png",@"tiff",@"baz",nil];

NSLog(@"Button Pressed");
[textField setStringValue:@"Test"];
int i; // Loop counter.

NSOpenPanel* openDlg = [NSOpenPanel openPanel];

[openDlg setCanChooseFiles:YES];
[openDlg setFileTypesArray:fileTypes];

Thanks.

You may wan to check out

[panel setAllowedFileTypes:[NSImage imageTypes]];

Or implement the delegate NSOpenSavePanelDelegate

and implement

- (BOOL)panel:(id)sender shouldEnableURL:(NSURL *)url {

    NSString * fileExtension = [url pathExtension];
    if (([fileExtension  isEqual: @""]) || ([fileExtension  isEqual: @"/"]) || (fileExtension == nil)) {
        return YES;
    }

    NSSet * allowed = [NSSet setWithArray:@[@"png", @"tiff", @"jpg", @"gif", @"jpeg"]];
    return [allowed containsObject:[fileExtension lowercaseString]];

}

How about [openDlg setAllowedFileTypes:fileTypes];?
