单击当前ViewController中的按钮时，如何显示当前ViewController的精确副本？

Question

I want to display another ViewController which must be copy of current ViewController with same UI(empty new tab like in Safari) when a button is clicked in current ViewController . For clear understanding, when we click + button iOS Safari then new tab in Safari is opened. I want to include this feature in my project.

Having a copy loaded is not like a new tab. You're looking to create a new instance of the same view controller. So, just instantiate it again with a new instance variable.
