Answer 1

According to your code, you setting equal frame for both table views:
CGRectMake(0, 0, self.view.frame.size.width, self.view.frame.size.height)
So by adding them to scroll view, you just placing them on top of each other.
Try to change the frame for second table view:
CGRectMake(320, 0, self.view.frame.size.width, self.view.frame.size.height)
