Hello, is it possible to specify that a NSMutableArray can only contain a certain type of objects. For example, if I want to store only this kind of objects :

@interface MyObject : NSObject {
    UInt8 value; 
}

In order to be able to use the instance variable like this :

- (void)myMethod:(NSMutableArray *)myArray{
    for (id myObject in myArray){
        [self otherMethod:myObject.value];
    }
}

because I'm getting this error :

request for member 'value' in something not a structure or union

Thank you for your help
