I have a custom class extending NSObject. I am maintaining NSMutableArray of this class objects. Here is the situation,

customObject {
   NSString *name;
   int ID;
   .....and many other properties;
}

customObjectsArray {
   customObject1,
   customObject2,
   ...etc
}

Now I am trying to use filterUsingPredicate to remove objects that has nil names, like below but it returns very few or none objects while I know that there are hundreds of objects that has name not nil or empty. Could someone please tell me what could be wrong here.

[customObjectsArray filterUsingPredicate:[NSPredicate predicateWithFormat:@"name != nil]];
