iOS UrlEncodedFormEntity Equivalent

Question

此方法的iOS的等效代码是什么？

public static String post(String url, String json_content) { 
    try { 
     HttpClient client = new DefaultHttpClient(); 
     HttpPost httppost = new HttpPost(url); 

     List<NameValuePair> nameValuePairs = new ArrayList<NameValuePair>(); 
     nameValuePairs.add(new BasicNameValuePair("", json_content.toString())); 

     httppost.setEntity(new UrlEncodedFormEntity(nameValuePairs)); 

     HttpResponse response = client.execute(httppost); 
     String responseBody = EntityUtils.toString(response.getEntity()); 

     Log.i("responseBody", responseBody); 

     return responseBody; 
    } catch (Exception e) { 
     e.printStackTrace(); 
    } 

    // Internal Error 
    return "ierror"; 
}

如果你正在寻找一种方式来编码的URL字符串中的iOS， 可以使用的NSStringstringByAddingPercentEscapesUsingEncoding:方法。
