问题
I am using UIPageControl and UIScrollView to move between the views by scrolling.
I have followed this tutorial.
I have a button in the first of the view controllers. I would like to send data to the second view controller and also change the page. I would like to know how it is done.
回答1:
You would need to have all of the view controllers created (born at least the first 2) rather than loading purely on demand (scroll).
Add a property to the first controller which holds a reference to the second controller. Set the reference when the instances are created.
When the button is tapped, use the reference to call a method on the second controller.
