objective c - Obj-c - How can I check if NSString contains one OR the other? -

i want check if nsstring 'name' contains "brittany" or "bob", following code doesn't seem trick?

viewcontroller.m

nspredicate *p = [nspredicate predicatewithformat:@"name contains[cd] %@ or name contains[cd] %@", @"brittany", @"bob"]; nsarray *filtered = [self.messages filteredarrayusingpredicate:p]; 

any idea should instead? can't seem syntax right. issue 'filtered' not returning arrays in string name containing "bob", ones in name contains "brittany".

here self.messages contains:

 messages data (             {             body = "hi";             endswaptime = "<null>";             "first name" = brittany;             name = brittany;             nid = 1803;             "node_title" = "re:";         },             {             body = "it brittany";             endswaptime = "<null>";             "first name" = brittany;             name = brittany;             nid = 1804;             "node_title" = "re:";          },             {             body = "hellooo :)\n";             endswaptime = "<null>";             "first name" = bob;             name = "bob";             nid = 1805;             "node_title" = "re:";           }     ) 

perhaps splitting predicate 2 separate predicates , combining nscompoundpredicate help?

nspredicate *p1 = [nspredicate predicatewithformat:@"name contains[cd] %@", @"brittany"]; nspredicate *p2 = [nspredicate predicatewithformat:@"name contains[cd] %@", @"bob"]; nscompoundpredicate *p = [nscompoundpredicate orpredicatewithsubpredicates:@[p1, p2]]; nsarray *filtered = [self.messages filteredarrayusingpredicate:p];
