Im using webview that inside it there is touchmove intraction.
The problem is, that when the event runing (user touchmove) the view itself moves too.
So i figure its with the swipe to dismiss.
However, when the page in webview have scroll (large height) so the swipe to dismiss doesn't active
There is a way to prevent only the web view from swipe navigation?
Thanks and sorry for bad english

On an iPad, you can use controller.modalPresentationStyle = UIModalPresentationFormSheet to show a centered modal on the screen. A common technique is to allow the user to dismiss the modal by clicking "outside" or "behind" it. This is covered in numerous other answers (Iphone SDK dismissing Modal ViewControllers on ipad by clicking outside of it,
Dismiss modal view form sheet controller on outside tap), usually by adding a tap gesture to the view's UIWindow.
My question is, how do I make this accessible to users in VoiceOver mode? The native action sheets allow clicks outside the sheet to dismiss, and even prompt the user, saying "double tap to dismiss popup window". How can I expose the UIWindow tap gesture in the same way?
From Apple:
https://support.apple.com/guide/iphone/learn-voiceover-gestures-iph3e2e2281/ios
Dismiss an alert or return to the previous screen: Two-finger scrub
(move two fingers back and forth three times quickly, making a “z”).
If the modal sheet is opened, we can prompt the user to "make a z gesture" to go back.
There is basically no way to do this with the FormSheet presentation. You can use the Popover presentation, but it behaves differently in some cases.
My solution was to check UIAccessibilityIsVoiceOverRunning() and add an extra close button element to the top of FormSheet that can be clicked via voiceover. I also implemented accessibilityPerformEscape for the global escape gesture.
The default interactivePopGestureRecognizer only works if you swipe left to right on the left edge of the screen. I would like to be able to perform this gesture by swiping anywhere on my screen. Apps like Reddit, Slack and Twitter have implemented this gesture, so I know it is possible.
So far, I have successfully popped to the previous VC using a swipe gesture self.navigationController.popViewControllerAnimated(true), however it does not show the top stack during the swipe. This action performs an immediate and quick animated transition to the other stack. I would like the animation to be similar to the default and slowly "peel away" the stack as the finger is dragged across the screen. This leads me to believe that it is possible to do this with a pan Gesture, however I am unsure how to slowly move the current view controller out of the frame and reveal the next stack during translation.
EDIT: SOLUTION
Here is the solution: https://stackoverflow.com/a/35510861/9159691
I think this is easier than the suggested solution and also works for all viewControllers inside that navigation and also for nested scrollviews.

Just install the pod and then use EZNavigationController instead of UINavigationController to have this behavior on all view controllers inside that navigation controller.
I have created a UIPercentDriven Transition which modally presents a popover view containing a tableView. Then, following stack exchange posts such as this one: In iOS, how to drag down to dismiss a modal?, I added a panGestureRecognizer to control the dismissal of the modal view. Then, I attempted to add functionality so that the user can continue to swipe downward once the tableview has reached the top to trigger the percent driven transition.
Here is a link to the project on github:https://github.com/KaplanAlex/modalViewDismissal
This transition was based on moving the frame of the modal view off of the screen. I also created the transition by using snapshots (which is commented out in the github project) and have the same issues. For some reason, the interactive dismissal works well unless the user moves the modal view back up after starting the dismissal and then continues to swipe upward after the modal view has reached the top of the view, the entire application seems to freeze. It doesnt crash, but also doesnt respond to taps anywhere on the screen. Even cancel button cannot be pressed. Has anyone encountered this issue before? Thanks for the help.
What's the best way to drag something out of a UIPopoverController, similar to how loops get dragged from the loop browser (I'm assuming it's a UIPopoverController) in Garageband on iOS? Meaning, the popover gets dismissed as soon as the user drags outside of it.
I tried implementing it via gestures, but as soon as I dismiss the popover, the gestures and therefore the dragging gets invalidated.
Is there a way to hide the popover, so I can dismiss it at the end of the drag? Or are there more elegant solutions?
I have been trying to implement drag and drop between pages of UIPageViewController, like when you move your apps between the pages of your iPhone's home screen. The problem is that when I start dragging the view and switch to the next page, the view freezes and becomes undraggable. Do you have any idea how NOT to stop the touch event when switching between pages?
