Use presentingViewController property of the UIViewController to dismiss. Eg: To present
使用 UIViewController 的presentingViewController 属性关闭。例如：呈现
vc.modalPresentationStyle = UIModalPresentationPopover;
vc.preferredContentSize = aPreffferedSize;
UIPopoverPresentationController *popcontroller = vc.popoverPresentationController;
popcontroller.barButtonItem = [[UIBarButtonItem alloc] initWithCustomView:view];
popcontroller.permittedArrowDirections = UIPopoverArrowDirectionAny;
popcontroller.delegate = self;
[self presentViewController:vc animated:YES completion:nil];
To dismiss programatically,
以编程方式关闭，
[[vc presentingViewController] dismissViewControllerAnimated:YES completion:NULL];
Hope this helps.
希望这可以帮助。
