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

For iOS 7 or above.

- (CGSize)preferredContentSize {
    return CGSizeMake(320, 550);
}

If you are a child of a container, re-direct the content size to yourself. E.g. In a UINavigationController subclass:

- (CGSize)preferredContentSize {
    return self.topViewController.preferredContentSize;
}
