Hello, I've got a short question. I have an NSArray filled with Cars (inherits from NSObject) Car has the @property NSString *engine (also regarded @synthesize ...)

Now I want tu filter the array using NSPredicate

 predicate = [NSPredicate predicateWithFormat:[NSString stringWithFormat:@"(engine like %@)", searchText]];

newArray = [ArrayWithCars filteredArrayUsingPredicate:predicate];

This throws an valueForUndefinedKey error. Is the predicateWithFormat correct?

thanks for your responses
