我用weex本身提供的WXWebComponent程式碼，從新寫了一個自己的WebComponent，並添加了攔截Url請求的方法，暴露給weex檔案使用。

問題描述

每次當我從myWebView攔截Url跳到一個weex文件，再次pop回來的時候，再點擊myWebView的時候，就沒辦法將callback事件回傳給weex檔。並出現以下錯誤提示

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

貼出我的webView攔截Url的部分程式碼

- (BOOL)webView:(UIWebView *)webView shouldStartLoadWithRequest:(NSURLRequest *)request navigationType:(UIWebViewNavigationType)navigationType { if (_startLoadEvent) { NSMutableDictionary *data = [NSMutableDictionary new]; [data setObject:request.URL.absoluteString ?:@"" forKey:@"url"]; [self fireEvent:@"pagestart" params:data]; } NSString * urlAbsoluteString= [request.URL absoluteString]; NSArray *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; }
