Question

I’m trying to find how to read data from my database in my iphone app. The database is in my server, what I tried is similar to how I do that in Android (I’m not sure if is the best way):

NSString *hostStr = @"http://www.myip/notices.php";


NSData *dataURL =  [NSData dataWithContentsOfURL: [ NSURL URLWithString: hostStr ]];    
NSString *serverOutput = [[NSString alloc] initWithData:dataURL encoding: NSASCIIStringEncoding];

NSLog(@"Mysql response:is %@",serverOutput);

What I get is “Mysql response: is Array”, what is true:

<?php
mysql_connect("localhost","user","pass");
mysql_select_db("database");


  $q = mysql_query("SELECT id, title FROM jos_content WHERE catid=12 AND state=1 AND DATE(publish_up) <= NOW() ORDER BY DATE(publish_up) DESC");

   while($e=mysql_fetch_assoc($q))

    $output[]=array("id" => $e['id'], "title" =>  utf8_encode($e['title']));
        echo $e;

print($output);

mysql_close();


?>

how should I do it?

Thank you in advance

Answer 1

From your php print the data as JSON it will be much easier to deal with it

In your PHP use

Instead of

print($output);

use

echo json_encode($output);

Then in your iOS app you could use this framewrok

To use SBJSon you would do the following

NSString *serverOutput = [[NSString alloc] initWithData:dataURL encoding: NSASCIIStringEncoding];
id object = [serverOutput JSONValue];
NSMutableDictionary *dictionary = (NSMutableDictionary *)object;

Now dictionary will contain the dictionary of values and keys
