QLPreviewItemTitle for an NSURL

[pinpoint]

Hi all,
I'm trying to set/return a QLPreviewItemTitle for an NSURL object. By default it's using the full filename, I want to strip off the .pdf extension.

I've tried subclassing NSURL to add the QLPreviewItemTitle method, and everything else I could think of... no luck. It seems like it should be easy- I want to use an NSURL as a QLPreviewItem (or something similar) i just want a different title for it.

Thoughts?

I added this code to the top of my QLPreviewController code:

@implementation NSURL (QLPreviewItem)
NSString *urlTitle;
- (NSURL *)previewItemURL
{
    return self.absoluteURL;
}
- (NSString *)previewItemTitle
{
    return urlTitle;
}
@end

Then in my controller where I'm setting the URL:

urlTitle = @"Testing";
