Search for multiple types with MPMediaPropertyPredicate

I have the following:

MPMediaPropertyPredicate *titlePredicate = [MPMediaPropertyPredicate predicateWithValue:textString 
                                                                            forProperty:MPMediaItemPropertyTitle
                                                                         comparisonType:MPMediaPredicateComparisonContains];

NSSet *predicateSet = [NSSet setWithObject:titlePredicate];
MPMediaQuery *searchQuery = [[MPMediaQuery alloc] initWithFilterPredicates:predicateSet];
NSArray *itemsFromTextQuery = [searchQuery items];

 for (MPMediaItem *song in itemsFromTextQuery) 
 {
     [arrayOfSongItems addObject:song];
 }

Which works great, but only searched the Title of the track. I'd like it to return results for the Title, the Artist and the Album name.

this works for me:

MPMediaQuery *searchQuery = [[MPMediaQuery alloc] init];
NSPredicate *test = [NSPredicate predicateWithFormat:@"title contains[cd] %@ OR albumTitle contains[cd] %@ OR artist contains[cd] %@", searchString, searchString, searchString];
NSArray *filteredArray = [[searchQuery items] filteredArrayUsingPredicate:test];

//NSLog(@"%@", [filteredArray valueForKeyPath:@"title"]);

for (MPMediaItem *song in filteredArray) 
{
    [arrayOfSongItems addObject:song];
}

I basically filter after getting all items from media query. I don't think my solution is better than filtering the query at the first place, but definitely better than searching three times separately. Or iterating through the array multiple times.

Try following code

 MPMediaQuery* query = [MPMediaQuery albumsQuery];

[query addFilterPredicate:[MPMediaPropertyPredicate predicateWithValue:self.strArtist forProperty:MPMediaItemPropertyArtist]]

[query addFilterPredicate:[MPMediaPropertyPredicate predicateWithValue:self.strTitle forProperty:MPMediaItemPropertyAlbumTitle]];
