如何将数据从iPhone发送到服务器并在站点中显示

Question

What I've learned and things that I'm not sure about if I need:

• A server like one of heroku provided.
• A database to handle what I will send.
• Something written for backend and mostly its written in php.
• To send data from iPhone to server with NSData and NSUrl with json .
• To receive what I sent from iPhone and handle it.

But I don't even know where to write PHP files to deploy on sites or anything about database creation.

Answer 2

At first start developing the web service .To start with a local server Use any webserver like XAMP,LAMP,tomcat,ect.

1. create a database using the phpMyadmin from your browser and also a user name to use by your application.

2. Use the URL like localhost/home/../api.php to get the api which interacts to our application.it depends on the server you use and you can get it XAMP , LAMP

3. Use php to code the api and for making the output in json, you can use json_encode() .

4. in Your iOS app, use a method to post the request, such as NSMutableURLRequest with required parameters.

5. To make a request in json format you can use

   NSString *jsonRequest = [jsonDict JSONRepresentation];

   This should be placed in the body of the post request. You can also use normal post
   request with parameters. I depends on how you process your request at the api.

6. To get the response from api, implement NSURLConnectionDataDelegate ,
   NSURLConnectionDataDelegate methods.

7. To get the json object from response

   json=[NSJSONSerialization JSONObjectWithData:responseData options:NSJSONReadingMutableLeaves error:&error];
