NSPredicate endswith multiple files

Question

I am trying to filter an array using a predicate checking for files ending in a set of extensions. How could I do it?

Would something close to \'self endswi

You don't want contains for an array, you want in. You also ideally want to filter by the path extension. So

NSArray *extensions = [NSArray arrayWithObjects:@"mp4", @"mov", @"m4v", @"pdf", @"doc", @"xls", nil];
NSArray *dirContents = [[NSFileManager defaultManager] contentsOfDirectoryAtPath:documentsDirectoryPath error:nil];
NSArray *files = [dirContents filteredArrayUsingPredicate:[NSPredicate predicateWithFormat:@"pathExtension IN %@", extensions]];
