   Its not so much a Cocos2D problem, but I figured you guys could help anyway. Basically I declared an NSArray in the header of a Scene. Initialized it in the init method, then tried calling it in a scheduled method but it crashes. Apparently the data is not carrying over or something. It works fine in the method itself; I can access the data in the init just fine, and likewise, if I initialized it in the scheduled method I can access it in there fine

   Dude, some code maybe?

   an example:

   //myArray is a member variable or possibly a global
   NSDate *aDate = [NSDate distantFuture];
   NSValue *aValue = [NSNumber numberWithInt:5];
   NSString *aString = @"a string";
   
   myArray = [NSArray arrayWithObjects:aDate, aValue, aString, nil];
   [myArray retain]; //did you forget to retain?

   Apparently yes, not so much that I forgot to retain, as I didn't know I had to do that, I'm a beginner in Objective-C
   In the header I had this
   @property(nonatomic, retain) NSArray* nsa;
   I thought that was enough, and I never had an issue needed to manually retain
   thanks for the help

   ok, if its a @property(nonatomic, retain) then do this instead:

   self.nsa = [NSArray arrayWithObjects:aDate, aValue, aString, nil];
   //no need to retain

   the setter isnt used unless you use 'self.'

   or you can just use alloc

   myArray = [[NSArray alloc] initWithObjects:aDate, aValue, aString, nil];
