问题 I have three tabs in my tabbar controller and I want to switch between these tabs just like tinder switches the tab using finger touch. I have done it using UISwipeGestureRecognizer but its not exactly same as that of Tinder (the dating app ) swiping.

I want the swiping should be controlled by finger touch.

问题 Problem: Starting from iOS 13.4 WebKit intercepts gestures that previously were passed to the system and could be handled by UIGestureRecognizer simultaneously Demo project: I created WKWebView and added it to UIViewController 's view. I created also UIPinchGestureRecognizer and added it to UIViewControler 's view as well. class ViewController: UIViewController, UIGestureRecognizerDelegate, WKNavigationDelegate { var webView: WKWebView? override func viewDidLoad() { super.viewDidLoad() let

问题 The title explains it all. Is there any way to detect a tap gesture on the status bar in iOS 11? I've already googled for this, and tried as suggested, but they all seem to be outdated answers somehow. I wonder if there's anyone who has already figured out how to solve this. 回答1: I use this code in the AppDelegate.swift override func touchesBegan(_ touches: Set<UITouch>, with event: UIEvent?) { super.touchesBegan(touches, with: event) let statusBarRect = UIApplication.shared.statusBarFrame

问题 I have a custom scroll view that works well before iOS 13 that uses UIPanGestureRecognizer: _panRecognizer = [[UIPanGestureRecognizer alloc] initWithTarget:self action:@selector(handlePan:)]; _panRecognizer.delegate = self; - (void)handlePan:(UIGestureRecognizer *)gestureRecognizer { UIPanGestureRecognizer* pgr = (UIPanGestureRecognizer*)gestureRecognizer; if (pgr.state == UIGestureRecognizerStateChanged) { // do something } } Now it didn't work well with iOS 13. The handlePan function does
