点击关闭时不要关闭 UIPopoverController

Question

after a bit of searching, I couldn't find an answer to something that seems like it would be useful to many.

Is there a way to make a UIPopoverController not dismiss when the user clicks somewhere on the outside? I want the user to have to use a cancel button (Yes, i realize this probably violates Apple's HIG somehow, but it's a rare case and makes sense from a User experience perspective).

Thanks for any help.

Answer 1

Just set the modalInPopover property on the UIViewController being displayed in the UIPopoverController .

popover = [[UIPopoverController alloc] initWithContentViewController:content];
content.modalInPopover = YES;
[popover presentPopoverFromBarButtonItem:sender permittedArrowDirections:UIPopoverArrowDirectionAny animated:YES];

Be aware that, as of iOS5 , you have to set modalInPopover inside of -viewDidAppear .

Answer 2

You can do hit-tests on where the tap occurred and in your popover's delegate return NO. - (BOOL)popoverControllerShouldDismissPopover:(UIPopoverController *)popoverController

Answer 3

So, I realize this is an old question. However, there's an easier answer for anyone searching for a solution today.

If you use a Storyboard Segue, you can set the passthrough property on the segue allowing interaction with other objects in the view. If you do so, clicking outside of the bounds of the popover won't close the popover.

Here's some more info: What are Anchor and Passthrough used for in popover segues?

And here's a excerpt from the Apple documentation:

To allow the user to interact with the specified views and not dismiss the popover, you can assign one or more views to the passthroughViews property.
