How to add buttons to scroll large image?

Question

iOS

On a large map, you need to place a lot of buttons. The map will scroll horizontally. Through the storyboard, it will only be possible to throw buttons a little, and when scrolling the image in the opened areas, the buttons can no longer be installed. How to create buttons on the entire map image? Thanks

Answer 1

If through the storyboard, then you can add a button to the visible area, then change the coordinates of the button.
Or you can add all the buttons in the code.
