   Hi all,

   Does anyone know how I can easily check a value inside an integer array?

   For example, I have an array filled with 12 integers. During my game I need to
   check to see if any one of those integers has been set to a value of 1.

   Thanks,

   Dan

   from NSArray

   - (NSUInteger)indexOfObject:(id)anObject

   Returns the lowest index whose corresponding array value is equal to a given object. hth, Codemattic

   Thanks Codemattic, my array is filled with integer primitives but not objects.

   Will that be an issue?

   Oh sorry, if you mean a c-based array then you have to search it yourself.

   I think it's best I use your original suggestion to use an array filled with Integer objects. But how can I 'wrap' a primitive integer value inside an Integer object?

   Thanks,

   Dan

   Not necessarily, if your data is in c then go with that. But if you want to use objective-c objects then use NSNumber's -numberWithInteger: or -numberWithInt:
