PSYouTubeExtractor Error while Extraction - objective-c

Question

I am trying to use the PSYouTubeExtractor in my Project, it is supposed to help with displaying YouTube videos inline by either downloading the mp4 or displaying it in a web view.
Here is how I implemented it so far:
-(void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath{
[PSYouTubeExtractor extractorForYouTubeURL:[deskUrls objectAtIndex:indexPath.row] success:^(NSURL *URL) {
NSLog(#"Finished extracting: %#", URL);
// show the movie!
} failure:^(NSError *error) {
NSLog(#"Failed to query mp4: %#", error);
}];
}
deskUrl is: this link for example and while this is extracting an error occurs:
[PSYouTubeExtractor doRetry_] [Line 105] Trying to load page...
2012-09-30 17:50:40.054 Tube[3378:907] -[__NSCFString absoluteURL]: unrecognized selector sent to instance 0x21027eb0
Well, I do not understand why, because this is just how it should be done. On the github page of the developer here, this is just the same code.
Anyone has an idea how to fix this?

Answer 1

It expects a NSURL instance but you obviously are providing an NSString instance.
Convert your string into a URL using the following call;
NSURL *youTubeURL = [NSURL URLWithString:[deskUrls objectAtIndex:indexPath.row]];
Then you may use the extractor factory/singleton as already done in your example;
[PSYouTubeExtractor extractorForYouTubeURL:youTubeURL success:^(NSURL *URL) {
NSLog(#"Finished extracting: %#", URL);
// show the movie!
} failure:^(NSError *error) {
NSLog(#"Failed to query mp4: %#", error);
}];
