How to make a Php response to Objective-C (iPhone)? -

-

my problem don't know how send data find (with select where) in php objective-c. know need make dataset how do it? people should use json can't find solution. indeed, don't know how make response in php? can me?

this php code:

$con = mysql_connect("url","username","password");  if (!$con){die('could not connect: ' . mysql_error());}     mysql_select_db("appiness", $con);  $bilgi= mysql_query("select c_id country c_name='$country'");  while($sutun= mysql_fetch_array($bilgi)) {     echo $sutun["c_id"]; }  mysql_close($con);

this objective-c code:

nsurl *url = [nsurl urlwithstring:@"someurl"]; asiformdatarequest *request = [asiformdatarequest requestwithurl:url];  [request setpostvalue:year1 forkey:@"year"]; [request setpostvalue:appy_level forkey:@"appy_level"]; [request setpostvalue:reasons forkey:@"reasons"]; [request setpostvalue:country forkey:@"country"]; [request setpostvalue:city forkey:@"city"]; [request setpostvalue:sex forkey:@"sex"]; [request setrequestmethod:@"post"]; [request setvalidatessecurecertificate:no]; [request setdelegate:self]; [request setdidfinishselector:@selector(requestdone:)]; [request startasynchronous];  - (void)requestdone:(asihttprequest *)request {     nsstring *response = [request responsestring];     nslog(@"%@",response); }  - (void)requestfailed:(asihttprequest *)request {          nserror *error = [request error];     nslog(@"%@",[error localizeddescription]); }

assuming know xml parsing can response xml follows using php code.

<?php     include_once('config.php');     header("content-type: text/xml");     $error_respond ='<?xml version="1.0" encoding="utf-8"?><result>failure</result>';     if($_server['request_method'] == 'post')     {         $return_val='<?xml version="1.0" encoding="utf-8"?>';         $id = $_post['userid'];         $return_val=$return_val.'<userdetails>';          $selusersql ="select * users userid = ".$id;         $selusertrs  = mysql_query($selusersql);         $selusernum = mysql_num_rows($selusertrs);         while($userrow = mysql_fetch_array($selusertrs))         {             $return_val=$return_val.'<userid>'.$userrow['user_id'].'</userid>';             $return_val=$return_val.'<username>'.$userrow['user_name'].'</username>';             $return_val=$return_val.'<email>'.xmlentities($userrow['user_email']).'</email>';         }         $return_val=$return_val.'</userdetails>';         echo $return_val;     }     else     {         echo $error_respond;         exit;     } ?>

sample output of above code (assuming user id posted 1 , details stored in db follows)

<?xml version="1.0" encoding="utf-8"?> <userdetails> <userid>1</userid> <username>dummyuser</username> <email>dummy@dummy.com</email> </userdetails>

if error occurred tried call url browser directly i.e. request method not post return following response showing error. (i believe post better get).

<?xml version="1.0" encoding="utf-8"?> <result>failure</result>

now last important part have parse response according requirement. search around , xmlparsing demo how xml parsing in iphone.

how set z-index drawing object when using drawingcontext.drawxxx() methods? the object drawn last have higher z index. can't change index of drawn objects. way draw in order. if using wpf (as placed tag), can use, example, canvas control. create shapes need like polyline obj = new polyline(); //... // ... set properties of obj and add them canvas uielementcollection: yourcanvasname.children.add(obj); //or yourcanvasname.children.insert(i, obj); first items of collection have higher z index. advantages in way: no need redraw on window changes, can anytime move objects , change order.
