Steps:

A) Link your UIButton to the popover's view controller using the Present As Popover segue type. I actually had to create a new project to get this to appear but it's probably something to do with the base SDK.

B) Make the View Controller containing the UIButton conform to the . E.g. In your MyViewController.m file add:

@interface MyViewController () 

C) Add the method below to the View Controller containing the UIButton:

- (UIModalPresentationStyle)adaptivePresentationStyleForPresentationController:(UIPresentationController *)controller {

    return UIModalPresentationNone;
}

D) Add the following into your prepareForSegue:sender: replacing your segue.identifier check:

if ([segue.identifier isEqualToString:@"CatSelectSegue"]) {
    UIViewController *dvc = segue.destinationViewController;
    UIPopoverPresentationController *controller = dvc.popoverPresentationController;
    if (controller) {
        controller.delegate = self;
    }
}

Code tested and proof it works:

Edit: My test app TPOPViewController.m file where the magic happens:

#import "TPOPViewController.h"

@interface TPOPViewController () //, UIAdaptivePresentationControllerDelegate>

@end

@implementation TPOPViewController

- (void)prepareForSegue:(UIStoryboardSegue *)segue sender:(id)sender {

    NSString *identifier = segue.identifier;
    if ([identifier isEqualToString:@"popover"]) {
        UIViewController *dvc = segue.destinationViewController;
        UIPopoverPresentationController *ppc = dvc.popoverPresentationController;
        if (ppc) {
            if ([sender isKindOfClass:[UIButton class]]) { // Assumes the popover is being triggered by a UIButton
                ppc.sourceView = (UIButton *)sender;
                ppc.sourceRect = [(UIButton *)sender bounds];
            }
            ppc.delegate = self;
        }
    }
}

- (UIModalPresentationStyle)adaptivePresentationStyleForPresentationController:(UIPresentationController *)controller {

    return UIModalPresentationNone;
}

@end
