Solution

This is a very old question, BUT:

You need to read the response data send by the server, the "0a7b2273..." part.

There, if you do:

NSString *responseString = [[NSString alloc] initWithData:thatData encoding:NSUTF8StringEncoding];

You'll see that the value is (it's JSON, I just linted it):

{
    "status": "0",
    "data": {
        "name": "Username cannot be longer than 60 characters but is currently 201 characters long.",
        "mail": "The e-mail address &lt;UITextField: 0x8dbc0b0; frame = (57 154; 153 30); text = &#039;deepaksood@deepak.com&#039;; clipsToBounds = YES; opaque = NO; autoresize = RM+BM; gestureRecognizers = &lt;NSArray: 0x8f6e8a0&gt;; layer = &lt;CALayer: 0x8daeee0&gt;&gt; is not valid."
    }
}

Your error was that in:

[params setValue:self.txtUserName forKey:@"name"];

self.txtEmail is a UITextField, not the textField.text. So, it was either self.txtEmail.text, or at some point, you wrote self.txtEmail = textField instead of self.txtEmail = textField.text. I guess this was also the case for the userName.

• So, after so much time, what's the thing that can still be applied nowadays:

Read the returned value! If might contain useful information on why it failed. When debugging, grab as much info as possible: HTTP Code, values send/read/received, etc.
