How to make a UIView or TableView to fit the preferredContentSize of a popover?

Question

I wanna show a popover with a 100X100 imageView or tableView. Usually I have to create an imageView on the corner Of the popoverView,like this.

But if I change the the preferredContentSize,I have to change the the size of imageView too.

Q1:
Is it the right way to create the content of a popover ?

Q2:
Is there a way to make the imageView or tableView to fit the preferredContentSize automatically?

Use [Auto Layout](https://developer.apple.com/library/tvos/documentation/UserExperience/Conceptual/AutolayoutPG/index.html) for this. — Rashwan L, Jan 06 '16 at 00:19

I've got the anwser!

Impelement code in presentating controller.

popoverController. preferredContentSize = popoverControoler.yourTableView.contentSize;
popoverController. preferredContentSize = popoverControoler.yourImageView.frame.size;

or
implement the code in popoverController (make sure yourView has been laid out)

-(void) viewDidAppear:(BOOL)animated{ self.preferredContentSize=yourTableView.contentSize; }

-(void) viewDidAppear:(BOOL)animated{ self.preferredContentSize=yourImageView.contentSize; }

it is better to set preferedContentSize in `code` override func viewDidLayoutSubviews() { super.viewDidLayoutSubviews() self.preferredContentSize = self.tableView.contentSize } `code` – user431791 May 23 '18 at 16:01
