如何在 UI 表格视图后面放置黑色不透明背景？

Question

I have a textfield that, when text is entered, pops up into a tableview . The tableview only takes up the bottom half of the screen, and when the tableview is showing at least one option, I would like to make the rest of the screen an opaque black. (Note, I'm not talking about the color of the tableview itself, but adding a dark tint to the rest of the screen.) The area on top of the tableview also has other elements, so it's not as simple as just changing the background color. Whenever I try to change it from where the tableview is controlled, I end up just changing the background of the tableview itself.

Here is a visual of something similar to what I'm trying to achieve:

Any help would be greatly appreciated!

Answer 1

1) Add your Selection options in new viewController names as optionPopUp(what ever you want).

2) set modalpresntationstyle of your new popUp as over current context with transition style as crossdisolve.

3) set background view color of new popUp viewcontroller with opacity(0.1 or 10%).

**4)**Present you popUp from source view controller ie in didselectrowat method of uitableview delegate
