这个问题主要是由于WKWebView没有对“gap”进行拦截，对比UIWebview的插件后，在

- (void)webView: (WKWebView*) webViewdecidePolicyForNavigationAction: (WKNavigationAction*) navigationActiondecisionHandler: (void(^)(WKNavigationActionPolicy)) decisionHandler

中加入拦截既可。

if ([[url scheme] isEqualToString:@"gap"]) {

        [vc.commandQueue fetchCommandsFromJs];

        // The delegate is called asynchronously in this case, so we don't have to us

        // flushCommandQueueWithDelayedJs (setTimeout(0)) as we do with hash changes.

        [vc.commandQueueexecutePending];

    }

后续Cordova方表示会跟随ios弃用UIWebview，还是拭目以待吧！目前只好用cordova-plugin-wkwebview-engine插件了！
