TechDegree: Could I get some advice on how to "display a mix of 3 and 4 choice questions, while re-spacing UI elements"?

I've put together an if statement that correctly detects when there is only 3 choices to the question.

And I'm trying to make it so that the button that has no question gets resized to "0", so that the other buttons then get moved to the correct places instead of just making the button hidden. (to meet the requirements: "spaced or resized appropriately, not simply hidden.")

But from everything I've tried, I'm finding that I can't change the button dimensions programmatically if the buttons have been created via the autolayout/Interface builder. If I disable the "Use Auto Layout" in the file inspector, then I'm able to modify the button dimensions programmatically.

So I understand that if the UI View is created programmatically then I can make changes.

But since we haven't covered how to create the whole interface programmatically in the lessons, I've sure there has to be a simpler and better way to do this. Maybe it needs a completely different approach than what I'm trying.

Any suggestions/advice to get me in the right direction is VERY appreciated!!!

Thanks in advance.
