php - UITextView prints JSON identifier instead of desired parsed data -


like title says, uitextview setup print data found within "username". instead of behaving appropriately, prints "username".

php code:

<?php      header('content-type: application/json');      $arr = array ('username'=>'derekshull', 'userbio'=>'this derekshulls bio','usersubmitted'=>'15');     echo json_encode($arr);   ?> 

objective c:

    - (void)viewdidload {     [super viewdidload];       nsurl *myurl = [[nsurl alloc]initwithstring:@"http://techinworship.com/json.php"];     nsdata *mydata = [[nsdata alloc]initwithcontentsofurl:myurl];     nserror *error;     nsarray *jsonarray = [nsjsonserialization jsonobjectwithdata:mydata options:nsjsonreadingmutablecontainers error:&error];      if(!error)     {         (id element in jsonarray) {             textview.text = [nsstring stringwithformat:@"%@", [element description]];             // text view contain last element loop         }     }     else{         textview.text = [nsstring stringwithformat:@"error--%@",[error description]];     } } 

what missing here? also, when run, application not crash , give error. however, following documented in debug area.

2014-03-24 20:20:53.258 testtest[11434:60b] unknown class textview in interface builder file. 

i don't have osx computer available can't evaluate code.

it seems array have in php code associative array , json similar. when parsing json string in obj-c code try assigning nsdictionary, way have access associative array.

nsdictionary *jsonarray = [nsjsonserialization jsonobjectwithdata:mydata options:nsjsonreadingmutablecontainers error:&error]; 

when using data in jsonarray don't iterate it, use nsdictionary method objectforkey get value want.

as example, value of username, can this:

[jsonarray objectforkey: @"username"] // jsonarray not array, dictionary 

and change text of textview, can following:

textview.text = [nsstring stringwithformat:@"%@", [jsonarray objectforkey: @"username"]]; 

ask if unclear!

cheers!
