一：URL拦截
<a href="darkangel://smsLogin?username=12323123&code=892845">短信验证登录</a>
- (void)webView:(WKWebView *)webView decidePolicyForNavigationAction:(WKNavigationAction *)navigationAction decisionHandler:(void (^)(WKNavigationActionPolicy))decisionHandler {
//可以通过navigationAction.navigationType获取跳转类型，如新链接、后退等
NSURL *URL = navigationAction.request.URL;
//判断URL是否符合自定义的URL Scheme
if ([URL.scheme isEqualToString:@"darkangel"]) {
//根据不同的业务，来执行对应的操作，且获取参数
if ([URL.host isEqualToString:@"smsLogin"]) {
NSString *param = URL.query;
NSLog(@"短信验证码登录, 参数为%@", param);
decisionHandler(WKNavigationActionPolicyCancel);
return;
}
}
decisionHandler(WKNavigationActionPolicyAllow);
NSLog(@"%@", NSStringFromSelector(_cmd));
}
二：scriptMessageHandler
创建webview
WKWebViewConfiguration *configuration = [[WKWebViewConfiguration alloc] init];
WKUserContentController *controller = [[WKUserContentController alloc] init];
configuration.userContentController = controller;
self.webView = [[WKWebView alloc] initWithFrame:self.view.bounds configuration:configuration];
self.webView.allowsBackForwardNavigationGestures = YES; //允许右滑返回上个链接，左滑前进
self.webView.allowsLinkPreview = YES; //允许链接3D Touch
self.webView.customUserAgent = @"WebViewDemo/1.0.0"; //自定义UA，UIWebView就没有此功能，后面会讲到通过其他方式实现
self.webView.UIDelegate = self;
self.webView.navigationDelegate = self;
[self.view addSubview:self.webView];
添加方法：currentCookies
[controller addScriptMessageHandler:self name:@"currentCookies"]; //这里self要遵循协 WKScriptMessageHandler
html 调用
window.webkit.messageHandlers.currentCookies.postMessage(document.cookie);
我在OC中将会收到WKScriptMessageHandler的回调
- (void)userContentController:(WKUserContentController *)userContentController didReceiveScriptMessage:(WKScriptMessage *)message {
if ([message.name isEqualToString:@"currentCookies"]) {
NSString *cookiesStr = message.body; //message.body返回的是一个id类型的对象，所以可以支持很多种js的参数类型(js的function除外)
NSLog(@"当前的cookie为： %@", cookiesStr);
}
}
- (void)dealloc {
//记得移除
[self.webView.configuration.userContentController removeScriptMessageHandlerForName:@"currentCookies"];
}
