Parsing JSON issue - iOS - ios

Question

I have a simple app which makes a POST request. And then data is returned. The problem is that the returned data is not JSON..... So how can I view it? Here is my code:
NSString *requestString = [NSString stringWithFormat:#"https://serveraddress.com"];
NSString *string = [NSString stringWithFormat:#"id=%#&olt_info=%#", #"test", #"renz"];
NSData *postData = [string dataUsingEncoding:NSUTF8StringEncoding];
NSMutableURLRequest *request = [NSMutableURLRequest requestWithURL:[NSURL URLWithString:requestString]];
NSLog(#"\n request str : %#",request);
[request setHTTPMethod:#"POST"];
[request setValue:#"application/x-www-form-urlencoded" forHTTPHeaderField:#"Content-Type"];
[request setHTTPBody:postData];
NSHTTPURLResponse *response = nil;
NSError *error = nil;
NSData *responseData = [NSURLConnection sendSynchronousRequest:request returningResponse:&response error:&error];
NSLog(#"The responce:\n\n%#", responseData);
if (error == nil && response.statusCode == 200) {
NSLog(#"%li", (long)response.statusCode);
NSError *err;
id JSon = [NSJSONSerialization JSONObjectWithData:responseData options:kNilOptions error:&err];
if (err) {
NSLog(#"%#",err);
}
else {
NSLog(#"Json %#",JSon);
}
}
else {
//Error handling
NSLog(#"%#", response);
}
This is the format of the returned data that I am trying to read:
new_token=509723045780uIRBWRBH24b
So I know the downloaded data gets stored in the NSData called "responseData". But if I print it using NSLog I just get this:
<61636365 73735f74 6f6b656e 3d313538 32353838 33343337 39343431 7c365f4d 6543436e 6b51716f 722d6e70 61746662 484d6458 526b3477>
So how do I read this???
Thank you for your time, Dan.

Answer 1

To get NSString from NSData use
NSString *decodedString = [[NSString alloc] initWithData:responseData encoding:NSUTF8StringEncoding];
maybe this string will have a valid JSON format.

Answer 2

NSString *requestString = [NSString stringWithFormat:#"https://serveraddress.com"];
NSString *string = [NSString stringWithFormat:#"id=%#&olt_info=%#", #"test", #"renz"];
NSData *postData = [string dataUsingEncoding:NSUTF8StringEncoding];
NSMutableURLRequest *request = [NSMutableURLRequest requestWithURL:[NSURL URLWithString:requestString]];
NSLog(#"\n request str : %#",request);
[request setHTTPMethod:#"POST"];
[request setValue:#"application/x-www-form-urlencoded" forHTTPHeaderField:#"Content-Type"];
[request setHTTPBody:postData];
NSHTTPURLResponse *response = nil;
NSError *error = nil;
NSData *responseData = [NSURLConnection sendSynchronousRequest:request returningResponse:&response error:&error];
*id json = [NSJSONSerialization JSONObjectWithData:responseData options:0 error:nil];*
NSLog(#"%#", json);
if (error == nil && response.statusCode == 200) {
NSLog(#"%li", (long)response.statusCode);
NSError *err;
id JSon = [NSJSONSerialization JSONObjectWithData:responseData options:kNilOptions error:&err];
if (err) {
NSLog(#"%#",err);
}
else {
NSLog(#"Json %#",JSon);
}
}
else {
//Error handling
NSLog(#"%#", response);
}
