UIWebView加载本地页面传参问题

感谢http://www.cocoachina.com/bbs/read.php?tid-93877.html此文作者

这两天做推送跳转到指定的本地html页面，发现用UIWebView加载本地html文件传参数页面加载出错。为了以后查询方便，现记录下来

UIWebView加载本地文件无参数用下面这种方法不会报错：

---

NSURL *url = [NSURL fileURLWithPath:[self.url stringByReplacingPercentEscapesUsingEncoding:NSUTF8StringEncoding]];

 NSURLRequest *request = [NSURLRequest requestWithURL:url];

---

带参数时（如.../index.html?FID=111）加载出错，提示在此服务器上找不到所请求的URL。

调试发现此时用fileURLWithPath的方式会把？转义成%3F导致请求失败。

解决办法参考stackoverflow:http://stackoverflow.com/questions/8286099/how-to-pass-arguments-to-fileurl

---

NSString *encodedPath = [self.url stringByAddingPercentEscapesUsingEncoding: NSUTF8StringEncoding];

    NSMutableString*urlStr =nil;

    if([self.urlParamArrcount] ==0||self.urlParamArr==nil) {

        urlStr = [NSMutableStringstringWithFormat:@"file://%@", encodedPath];

    }else{

        urlStr = [NSMutableStringstringWithFormat:@"file://%@", encodedPath];

        for(inti=0; i<[self.urlParamArrcount]; i++) {

            NSDictionary* tempDic =self.urlParamArr[i];

            if(i==0) {

                [urlStrappendFormat:@"?%@=%@",[tempDicobjectForKey:@"key"],[tempDicobjectForKey:@"value"]];

            }else{

                [urlStrappendFormat:@"&%@=%@",[tempDicobjectForKey:@"key"],[tempDicobjectForKey:@"value"]];

            }

        }

    }

    NSURL*url = [NSURLURLWithString:urlStr];

    NSURLRequest *request= [NSURLRequest requestWithURL:url];

    [_webloadRequest:request];

使用上面方法就可以正常加载了，再次感谢http://www.cocoachina.com/bbs/read.php?tid-93877.html此文作者的分享
