问题 I am developing an application where I have used the Pan Gesture as well as Swipe Gesture. So every time I do the Swipe Gesture but the method from the Pan Gesture is always getting called and Swipe Gesture method is not getting called. Is there any priority between all the gesture method? 回答1: You can call them in parallel by implementing the following method of the UIGestureRecognizerDelegate protocol: - (BOOL)gestureRecognizer:(UIPanGestureRecognizer *)gestureRecognizer

I use UISwipeGestureRecognizer and my overwritten -(void)touchesBegan...,-(void)touchesEnded...,-(void)touchesMoved... methods. It seems that touchesBegan and touchesMoved keep tracking touches untill Swipe Gesture recognized and touchesEnded is not called (same as touchesCancelled). But I need both swipe gesture recognizer and touchesEnded to do the job, how can i do it? Feel Physics At first, drag and drop the Swipe Gesture Recognizer from Libraries into View. And you check off the item canceled in View . Write code to respond swipe gesture. - (IBAction)swipe:(id)sender { v.backgroundColor =

Preload next page in UIPageViewController

问题 I've looked many, many places and have yet to find some good sample code showing how to pre-load the "next" page in a UIPageViewController. There are a few answers on SO detailing some theoretical ways to do it (see this question) but no one has yet to post a working example. In the workflow of my app I'm showing 1 page per screen and I want to have the "next" screen preloaded because as it is, swiping to the next page can be very slow, sometimes requiring 2 swipes (if you swipe too fast) in

Swipe gesture for back/forward in UIWebView?

由 人盡茶涼 提交于 2019-12-04 05:30:53
I have a WebView in my app. Because it is a tabbed application I'm not able to add buttons for going back/forward on the website. I want to go back/forward by swiping. Right swipe from the left side/edge is back… like in Safari browser for iOS. How can I do it? I think i should use "Screen Edge Pan Gesture Recognizer", right? Why not just use a swipe gesture recognizer? UISwipeGestureRecognizer *swipeLeft = [[UISwipeGestureRecognizer alloc] initWithTarget:self action:@selector(handleSwipe:)]; UISwipeGestureRecognizer *swipeRight = [[UISwipeGestureRecognizer alloc] initWithTarget:self action:
