I am having problems with "setAllowedFileTypes" on an NSOpenPanel

The documentations says that you can pass an array of file extensions or UTI's.
I am wanting to open files that have either a "cct" extension or a file type of "CDIF". I verified the UTI by dumping it out using the following code.

theUTIDictionary=(NSDictionary *)UTTypeCopyDeclaration((CFStringRef) uti);

theEnum=[theUTIDictionary keyEnumerator];

for (NSString *s in theEnum)
{
NSLog(@"key is %@, value is %@",s, [theUTIDictionary objectForKey: s]);
}

It contains the appropriate entries for both the extension and the file type.

When I run the App it does not allow me to select files with the old file type of "CDIF". Yes , I have verified that the file does have that type(GetFileInfo in Terminal). Any idea's.

Thanks

Neil

I know Apple likes us to use UTI's but I'm still using extensions.

[myOpenPanel setAllowedFileTypes:[NSArray arrayWithObjects:mad:"cct", @"CDIF", nil]];

Thanks for the prompt reply. What you suggest will work for files with extensions but how about files with the old "File Type"? That is why I used UTI's , I thought I could use one method to handle both cases.
