WKWebView 報錯unsupported URL

最近在使用wkwebview 使用的時候坑比較多，比如在自定義的 URL Scheme 類型鏈接 會報錯 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 點擊a 標簽中的pdf 不跳轉(zhuǎn)

有一種情況是不允許 跳轉(zhuǎn)

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

    NSLog(@"%@",navigationResponse.response.URL.absoluteString);
    //允許跳轉(zhuǎn)
    decisionHandler(WKNavigationResponsePolicyAllow);

}

還有一種情況 就是 點擊 a 標簽跳轉(zhuǎn) 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];
        }
}

希望可以解決你的問題
