How To Dynamically change the contentSize of UIPopoverController?

Question

I have a UIViewController that contains a UITableView. This UIViewController is being displayed in a UIPopoverController.

Answer 1

iOS8/9 solution - just override preferredContentSize and force the table view to layout prior to returning it's contentSize.

- (CGSize)preferredContentSize {
    [self.tableView layoutIfNeeded];
    return self.tableView.contentSize;
}
