这段代码报错： `

• (void)webView:(WKWebView *)webView decidePolicyForNavigationAction:(WKNavigationAction *)navigationAction decisionHandler:(void (^)(WKNavigationActionPolicy))decisionHandler { if (webView != _webView) { return; } NSURL *url = navigationAction.request.URL; __strong typeof(_webViewDelegate) strongDelegate = _webViewDelegate;

  if ([_base isCorrectProcotocolScheme:url]) { if ([_base isBridgeLoadedURL:url]) { [_base injectJavascriptFile]; } else if ([_base isQueueMessageURL:url]) { [self WKFlushMessageQueue]; } else { [_base logUnkownMessage:url]; } decisionHandler(WKNavigationActionPolicyCancel); }

  if (strongDelegate && [strongDelegate respondsToSelector:@selector(webView:decidePolicyForNavigationAction:decisionHandler:)]) { [_webViewDelegate webView:webView decidePolicyForNavigationAction:navigationAction decisionHandler:decisionHandler]; } else { decisionHandler(WKNavigationActionPolicyAllow); } } `

可以修改为： `- (void)webView:(WKWebView *)webView decidePolicyForNavigationAction:(WKNavigationAction *)navigationAction decisionHandler:(void (^)(WKNavigationActionPolicy))decisionHandler { if (webView != _webView) { return; } NSURL *url = navigationAction.request.URL; __strong typeof(_webViewDelegate) strongDelegate = _webViewDelegate;

if ([_base isCorrectProcotocolScheme:url]) {
    if ([_base isBridgeLoadedURL:url]) {
        [_base injectJavascriptFile];
    } else if ([_base isQueueMessageURL:url]) {
        [self WKFlushMessageQueue];
    } else {
        [_base logUnkownMessage:url];
    }
    decisionHandler(WKNavigationActionPolicyCancel);
}else
{
    if (strongDelegate && [strongDelegate respondsToSelector:@selector(webView:decidePolicyForNavigationAction:decisionHandler:)]) {
        [_webViewDelegate webView:webView decidePolicyForNavigationAction:navigationAction decisionHandler:decisionHandler];
    } else {
        decisionHandler(WKNavigationActionPolicyAllow);
    }
}
