Re-order subviews in a full view

Question

• I have a view which has 3 subviews in it which are stacked
• Each subview is associated with a button
• On button event, I remove all subviews and then
• I add the relevant subview

However, removing and adding subviews create a performance problem

So, I was hoping to re-order subviews on button press rather than removing them.

How can I re-order stacked subviews?

Answer 1

You can reorder subviews by calling the following two methods:

parentView.bringSubviewToFront(subview)

or

parentView.sendSubviewToBack(subview)
