Question

I have NSMutableArray with NSString objects.
How can I filter it to get only the objects, which DOES NOT contain a string?
I tried NSPredicate to filter objects which contain a string:

NSString *match = @"My text"; 

    NSPredicate *sPredicate = [NSPredicate predicateWithFormat:@"SELF CONTAINS[cd] %@", match];

    [self.filesList setArray:[self.filesList filteredArrayUsingPredicate:sPredicate]];

Is there anything similar, but to filter it vice-versa? Some kind of ” !contains ” ?

Answer 1

Use this instead:

NSPredicate *sPredicate = [NSPredicate predicateWithFormat:@"NOT (SELF CONTAINS[cd] %@)", match];
