Please see this..

NSMutableArray *arrNumbers = [[NSMutableArray] alloc] initWithCapacity:[YOURSTRING length]];

for (i=0;i<[YOURSTRING length];i++) 
{
  unichaar ch = [YOURSTRING characterAtIndex:i];
  NSLog(@"Processing charachter %c",ch);
  // If you really want
  [arrNumbers addObject:(id)ch];
}
