ios - 用WXWebComponent代码创建一个新的web组件,出现以下问题

我用weex本身提供的WXWebComponent代码,从新写了一个自己的WebComponent,并添加了拦截Url请求的方法,暴露给weex文件使用。

问题描述

每次当我从myWebView拦截Url跳到一个weex文件,再次pop回来的时候,再次点击myWebView的时候,就没办法将callback事件返回给weex文件。并出现以下错误提示

WeexDemo[23225:9905854] void SendDelegateMessage(NSInvocation *): delegate (webView:decidePolicyForNavigationAction:request:frame:decisionListener:) failed to return after waiting 10 seconds. main run loop mode: kCFRunLoopDefaultMode

贴出我的webView拦截Url的部分代码

- (BOOL)webView:(UIWebView *)webView shouldStartLoadWithRequest:(NSURLRequest *)request navigationType:(UIWebViewNavigationType)navigationType
{
    if (_startLoadEvent) {
        NSMutableDictionary<NSString *, id> *data = [NSMutableDictionary new];
        [data setObject:request.URL.absoluteString ?:@"" forKey:@"url"];
        [self fireEvent:@"pagestart" params:data];
    }
    
    NSString * urlAbsoluteString= [request.URL absoluteString];
    NSArray <NSString *>*schemes = self.schemesCallBacks.allKeys;
    for (NSString *scheme in schemes) {
        NSError *error = nil;
        NSRegularExpression *regExp = [NSRegularExpression regularExpressionWithPattern:scheme options:NSRegularExpressionCaseInsensitive error:&error];
        if (!error) {
            NSRange range = [regExp rangeOfFirstMatchInString:urlAbsoluteString options:NSMatchingReportProgress range:NSMakeRange(0, urlAbsoluteString.length)];
            if (range.location != NSNotFound) {
                WXCallback callBack = self.schemesCallBacks[scheme];
                callBack(@{@"url": [request.URL absoluteString]});
                return NO;
            }
        } else {
            WXLog(@"created regExp error:  %@", error);
        }
    }
    return YES;
}

    self.schemesCallBacks里存的value是WXCallback?建议换成WXKeepAliveCallback试试
