本文展示了如何使用AFHTTPSessionManager发起GET请求获取新闻详情，并将其显示在UIWebView中。
AFHTTPSessionManager *manger = [AFHTTPSessionManager manager];
[manger GET:@"http://app218.zhb.hebnews.cn:9002/app_v1.4.2/getnewsbyid.do?newsid=38420&appkey=zhb&userid=0&uniquecode=4C42D8DA-89DD-47CA-B022-296AF0268024" parameters:nil success:^(NSURLSessionDataTask *task, id responseObject) {
NSString *str = responseObject[@"data"][@"htmlbody"];
UIWebView *webView = [[UIWebView alloc] initWithFrame:CGRectMake(10, 200, 300, 400)];
[webView loadHTMLString:str baseURL:nil];
[self.view addSubview:webView];
} failure:^(NSURLSessionDataTask *task, NSError *error) {
}];
