Usage

Sample usage of the ARSPopover might look like this:

- (IBAction)showPopoverWithWebView:(id)sender {
    ARSPopover *popoverController = [ARSPopover new];
    popoverController.sourceView = self.buttonWithWebView;
    popoverController.sourceRect = CGRectMake(CGRectGetMidX(self.buttonWithWebView.bounds), CGRectGetMaxY(self.buttonWithWebView.bounds), 0, 0);
    popoverController.contentSize = CGSizeMake(400, 600);
    popoverController.arrowDirection = UIPopoverArrowDirectionUp;

    [self presentViewController:popoverController animated:YES completion:^{
        [popoverController insertContentIntoPopover:^(ARSPopover *popover, CGSize popoverPresentedSize, CGFloat popoverArrowHeight) {
            CGFloat originX = 0;
            CGFloat originY = 0;
            CGFloat width = popoverPresentedSize.width;
            CGFloat height = popoverPresentedSize.height - popoverArrowHeight;

            CGRect frame = CGRectMake(originX, originY, width, height);
            UIWebView *webView = [[UIWebView alloc] initWithFrame:frame];
            webView.scalesPageToFit = YES;
            [webView loadRequest:[NSURLRequest requestWithURL:[NSURL URLWithString:@"https://google.com"]]];
            [popover.view addSubview:webView];
        }];
    }];
}

Required properties' configurations

In order to get a working popover, you need to specify next properties:

• popoverController.sourceView - The view containing the anchor rectangle for the popover.

popoverController.sourceView = self.buttonWithWebView;

• popoverController.sourceRect - The rectangle in the specified view in which to anchor the popover.

popoverController.sourceRect = CGRectMake(CGRectGetMidX(self.buttonWithWebView.bounds), CGRectGetMaxY(self.buttonWithWebView.bounds), 0, 0);

• popoverController.contentSize - The preferred size for the popover’s view.

popoverController.contentSize = CGSizeMake(400, 600);

• And the last, most important thing - you have to call method insertContentIntoPopover and pass a block of code, which should add subviews to popover's view you wish to see.

Be sure to call this method only after you have presented popup. Otherwise you might get wrong size in popoverPresentedSize.

[popoverController insertContentIntoPopover:^(ARSPopover *popover, CGSize popoverPresentedSize, CGFloat popoverArrowHeight) {
    CGFloat originX = 0;
    CGFloat originY = 0;
    CGFloat width = popoverPresentedSize.width;
    CGFloat height = popoverPresentedSize.height - popoverArrowHeight;

    CGRect frame = CGRectMake(originX, originY, width, height);
    UIWebView *webView = [[UIWebView alloc] initWithFrame:frame];
    webView.scalesPageToFit = YES;
    [webView loadRequest:[NSURLRequest requestWithURL:[NSURL URLWithString:@"https://google.com"]]];
    [popover.view addSubview:webView];
}];

Optional delegate methods

You can conform to ARSPopoverDelegate protocol, so that you could receive delegate calls from UIPopoverPresentationController. You can implement following delegate methods:

- (void)popoverPresentationController:(UIPopoverPresentationController *)popoverPresentationController willRepositionPopoverToRect:(inout CGRect *)rect inView:(inout UIView *__autoreleasing *)view;

- (BOOL)popoverPresentationControllerShouldDismissPopover:(UIPopoverPresentationController *)popoverPresentationController;

- (void)popoverPresentationControllerDidDismissPopover:(UIPopoverPresentationController *)popoverPresentationController;
