WKWebView 报错unsupported URL

最近在使用wkwebview 使用的时候坑比较多，比如在自定义的 URL Scheme 类型链接 会报错 unsupported URL

- (void)webView:(WKWebView *)webView decidePolicyForNavigationAction:(WKNavigationAction *)navigationAction decisionHandler:(void (^)(WKNavigationActionPolicy))decisionHandler
{
         NSURL *currentURL = navigationAction.request.URL;
        NSString *urlString = (currentURL) ? currentURL.absoluteString : @"";
        if ([urlString containsString:@"weixin://wap/pay"]) {
            [[UIApplication sharedApplication] openURL:self.currentUrl];
            decisionHandler(WKNavigationActionPolicyCancel);
            return;
        }
        decisionHandler(WKNavigationActionPolicyAllow);
}

WKWebView 点击a 标签中的pdf 不跳转

有一种情况是不允许 跳转

- (void)webView:(WKWebView *)webView decidePolicyForNavigationResponse:(WKNavigationResponse *)navigationResponse decisionHandler:(void (^)(WKNavigationResponsePolicy))decisionHandler{

    NSLog(@"%@",navigationResponse.response.URL.absoluteString);
    //允许跳转
    decisionHandler(WKNavigationResponsePolicyAllow);

}

还有一种情况 就是 点击 a 标签跳转 blank

-(WKWebView *)webView:(WKWebView *)webView createWebViewWithConfiguration:(WKWebViewConfiguration *)configuration forNavigationAction:(WKNavigationAction *)navigationAction windowFeatures:(WKWindowFeatures *)windowFeatures
{
    if (!navigationAction.targetFrame.isMainFrame) {
        [webView loadRequest:navigationAction.request];
    }
    return nil;
}

- (void)webView:(WKWebView *)webView decidePolicyForNavigationAction:(WKNavigationAction *)navigationAction decisionHandler:(void (^)(WKNavigationActionPolicy))decisionHandler
{
        if (navigationAction.targetFrame == nil) {
            [webView loadRequest:navigationAction.request];
        }
}

希望可以解决你的问题
