iOS 13 - UIPopoverPresentationController sourceview content visible in the arrow

Question

When I am displaying some view in UIPopoverPresentationController and presenting it as popover

popoverCon?.modalPresentationStyle = UIModalPresentationStyle.popover

the content have moved upward toward and a some part is being display in the arrow.

Further I had border around the popover

popoverCon?.view.layer.borderColor = .orange
popoverCon?.view.layer.borderWidth = 1.0;
popoverCon?.view.layer.cornerRadius = 10.0;
popoverCon?.view.layer.masksToBounds = false;

it is not showing toward the part where arrow is but it displays a little of the border line in the tip of the arrow.

This was working fine until iOS 12 but in iOS 13 this issue is coming.

Any suggestions on how I can solve this?

Answer 1

The top of my tableView content was cut off by the arrow. This is how I fixed it in my case (code inserted in my tableViewController Swift file):

override func viewSafeAreaInsetsDidChange() {
    if #available(iOS 11.0, *) {
        super.viewSafeAreaInsetsDidChange()
        self.tableView.contentInset = UIEdgeInsets(top: self.tableView.safeAreaInsets.top, left: 0, bottom: 0, right: 0)
    }
}

My solution in Obj-C, for those who need an obj-c solution.

I had previously only popovercontroller, that was creating the error like shown in the question. I renamed it to childController for clarity and created a containing popoverController to make the solution given by @SaintMSent work in my situation of only one view originally. Also used https://stackoverflow.com/a/47076040/2148757 solution and https://useyourloaf.com/blog/self-sizing-child-views/ to resize appropriately since all of my childControllers set the preferred content size frequently.

//Create container popover controller and add child to it
UIViewController* popoverController = [[MyParentPopoverController alloc] init];
[popoverController.view addSubview:childController.view];
[popoverController addChildViewController:childController];
[popoverController setPreferredContentSize:childController.preferredContentSize];
//set popover settings on container
popoverController.modalPresentationStyle = UIModalPresentationPopover;
popoverController.popoverPresentationController.sourceRect = sourceRect;
popoverController.popoverPresentationController.sourceView = buttonView;
popoverController.popoverPresentationController.permittedArrowDirections = direction;
//Fix ios13 'bug' that Apple claims is a feature
UILayoutGuide* guide = popoverController.view.safeAreaLayoutGuide;
childController.view.translatesAutoresizingMaskIntoConstraints = NO;
[childController.view.leadingAnchor constraintEqualToAnchor:guide.leadingAnchor].active = YES;
[childController.view.trailingAnchor constraintEqualToAnchor:guide.trailingAnchor].active = YES;
[childController.view.topAnchor constraintEqualToAnchor:guide.topAnchor].active = YES;
[childController.view.bottomAnchor constraintEqualToAnchor:guide.bottomAnchor].active = YES;
[popoverController.view layoutIfNeeded];
//Show the popover

...

@interface MyParentPopoverController : UIViewController

@end

@implementation MyParentPopoverController

-(void)preferredContentSizeDidChangeForChildContentContainer:(id <UIContentContainer>)container {
    [super preferredContentSizeDidChangeForChildContentContainer:container];
    [self setPreferredContentSize:container.preferredContentSize];
}

@end

Note: I didn't check for ios11 compatibility because my user base is restricted to not use it.
