ios – allowsBackForwardNavigationGestures = true在xcode 7.1中不起作用

概述import UIKitimport WebKitclass ViewController: UIViewController, WKNavigationDelegate {var webView : WKWebView!override func loadView() { webView = WKWebView() webView.navigationDelegat

import UIKitimport WebKitclass VIEwController: UIVIEwController,WKNavigationDelegate {var webVIEw : WKWebVIEw!overrIDe func loadVIEw() {    webVIEw = WKWebVIEw()    webVIEw.navigationDelegate = self    self.vIEw = webVIEw}overrIDe func vIEwDIDLoad() {    super.vIEwDIDLoad()    let url = NSURL(string: "http://boooo.com")    webVIEw.loadRequest(NSURLRequest(URL: url!))    webVIEw.allowsBackForwardNavigationGestures = true}overrIDe func dIDReceiveMemoryWarning() {    super.dIDReceiveMemoryWarning()}}

一切正常,但allowBackForwardNavigationGestures = true不适用于xcode 7.1.不能在wkwebvIEw中前进和后退.

解决方法 看起来它干扰了navigationController的interactivePopGestureRecognizer(如果你有的话).

overrIDe func vIEwWillAppear(_ animated: Bool) {    super.vIEwWillAppear(animated)    self.navigationController?.interactivePopGestureRecognizer?.isEnabled = false}overrIDe func vIEwWilldisappear(_ animated: Bool) {    super.vIEwWilldisappear(animated)    self.navigationController?.interactivePopGestureRecognizer?.isEnabled = true}

所以我在导航堆栈中使用WKWebVIEw时禁用了这个属性！
