looks like my syntax is wrong. Does not compile

  Aobject is type of Myobject*
  
  it has an array for 6 intergers
  
  Aobject.myArray = [NSArray arrayWithObjects:[NSNumber numberWithInt:
  1], [NSNumber numberWithInt: 2],[NSNumber numberWithInt:3], [NSNumber
  numberWithInt:4], [NSNumber numberWithInt:5],[NSNumber numberWithInt:
  6], nil];
  
  Now I would like to randomize it.
  
  for (int j = 0; j < 6; j++)
  {
  NSNumber* aNumber = [Aobject _Edge] numberWithInt:j;
      // looks like my syntax is wrong. Does not compile
  
  }

  Your syntax is indeed incorrect - you may want to review Apple's
  Objective-C documentation [1]. Moreover, it's not clear how this is
  supposed to randomize the array, as no random numbers are involved.

  Objective-C isn't smalltalk.  All message expressions have to be
  enclosed in square brackets:
  
  NSNumber* aNumber = [[Aobject _Edge] numberWithInt:j];
