代理實(shí)現(xiàn)<WKUIDelegate, WKNavigationDelegate,WKScriptMessageHandler>

代理注冊viewWillAppear方法里

[self.MyWKWebView.configuration.userContentController addScriptMessageHandler:self name:@"first"];

代理移除viewWillDisappear方法里

[self.MyWKWebView.configuration.userContentController removeScriptMessageHandlerForName:@"first"];

WKwebview 內(nèi)部設(shè)置

? WKWebViewConfiguration *config = [[WKWebViewConfiguration alloc] init];

? ? ? ? config.userContentController = [[WKUserContentController alloc] init];

? ? ? ? //在創(chuàng)建wkWebView時(shí)，需要將被js調(diào)用的方法注冊進(jìn)去,oc與js端對(duì)應(yīng)實(shí)現(xiàn)

? ? ? ? NSString *js = @" $('meta[name=description]').remove(); $('head').append( '' );";

? ? ? ? WKUserScript *script = [[WKUserScript alloc] initWithSource:js injectionTime:WKUserScriptInjectionTimeAtDocumentEnd forMainFrameOnly:NO];

? ? ? ? NSMutableString *javascript = [NSMutableString string];

? ? ? ? [javascriptappendString:@"document.documentElement.style.webkitTouchCallout='none';"];//禁止長按

? ? ? ? WKUserScript *noneSelectScript = [[WKUserScript alloc] initWithSource:javascript injectionTime:WKUserScriptInjectionTimeAtDocumentEnd forMainFrameOnly:YES];

? ? ? ? [config.userContentController addUserScript:script];

? ? ? ? [config.userContentControlleraddUserScript:noneSelectScript];

? ? ? ? [config.userContentController addScriptMessageHandler:self name:@"first"];

? ? ? ? config.preferences = [[WKPreferences alloc] init];

? ? ? ? config.preferences.minimumFontSize = 10;

? ? ? ? config.preferences.javaScriptEnabled = YES;

? ? ? ? config.preferences.javaScriptCanOpenWindowsAutomatically = YES;

? ? ? ? config.allowsInlineMediaPlayback = true;

Hand 代理

#pragma mark-

#pragma mark - ?? WKScriptMessageHandler ??

- (void)userContentController:(WKUserContentController*)userContentControllerdidReceiveScriptMessage:(WKScriptMessage*)message {

if ([message.name isEqualToString:@"first"]) {//分享}

}

前端丟消息方法

iOS ，用window.webkit.messageHandlers.webCallShare.postMessage 這個(gè)發(fā)消息
