给UIWebView添加MJRefresh

- (void)loadData:(NSString *)urlString{
    [self.orderWebView.scrollView.mj_header endRefreshing];
    NSString *reqUrlStr = [NSString stringWithFormat:@"%@%@",PAGE_URL,urlString];
    NSURL *reqUrl = [NSURL URLWithString:reqUrlStr];
    self.orderWebView.scrollView.mj_header = [MJRefreshNormalHeader headerWithRefreshingBlock:^{
        [self.orderWebView loadRequest:[[FXWebView shareManager] addHeaderIntoRequest:reqUrl]];
    }];
    [self.orderWebView.scrollView.mj_header beginRefreshing];
    
//    NSString *urlStr = [NSString stringWithFormat:@"%@%@",kAppURL, urlString];
//    NSURL *url = [NSURL URLWithString:urlStr];
//    NSURLRequest *request = [NSURLRequest requestWithURL:url];
//    [self.orderWebView loadRequest:request];
