查看一下错误对象的里面的内容，发现是域名出了问题，改成以下这样就可以了。

NSURL *url1 = [NSURL URLWithString:@"http://www.baidu.com/"];
    NSURLRequest *request = [NSURLRequest requestWithURL:url1 cachePolicy:NSURLRequestReloadIgnoringLocalAndRemoteCacheData timeoutInterval:5];
    NSHTTPURLResponse *response;
    NSError * error;
    [NSURLConnection sendSynchronousRequest:request returningResponse: &response error: &error];
