NSPredicate with AND and OR issues

Question

I have the following NSPredicate:

 fetchRequest.predicate = [NSPredicate predicateWithFormat:@"url = %@ AND type = %@ OR type = %@", newsStory.url, [NSNumber numberWithInt:StoryHighlighted], [NSNumber numberWithInt:StorySavedAndHighlighted]];

I wanted to fetch a story with this particular URL and type of (highlighted or highlightedandsaved). However the query above doesn't seem to work. What am I doing wrong?

Answer 1

As simple as wrapping your OR in brackets to save any confusion?

fetchRequest.predicate = [NSPredicate predicateWithFormat:@"url = %@ AND (type = %@ OR type = %@)", newsStory.url, [NSNumber numberWithInt:StoryHighlighted], [NSNumber numberWithInt:StorySavedAndHighlighted]];

Answer 2

You can try to do this:

fetchRequest.predicate = [NSPredicate predicateWithFormat:@"url = '%@' AND( type = %@ OR type = %@"), newsStory.url, [NSNumber numberWithInt:StoryHighlighted], [NSNumber numberWithInt:StorySavedAndHighlighted]];
