You can put something like this in the place of your jsonRequest string (the code uses the SBJson framework):

NSDictionary *container = [[NSDictionary alloc] initWithObjectsAndKeys:
                            [loginTextField text], @"login",
                            [passwordTextField text], @"password",
                            [mailTextField text], @"mail"];

NSString *jsonString = [container JSONRepresentation];
// don't forget to release container if not using ARC AFTER creating the NSData object
