NSDictionary *properties = [NSDictionary dictionaryWithObjectsAndKeys:
                            req.URL, NSHTTPCookieOriginURL,
                            @"MLSTORAGE", NSHTTPCookieName,
                            @"1234567890", NSHTTPCookieValue,
                            nil];
NSHTTPCookie *cookie = [NSHTTPCookie cookieWithProperties:properties];
NSLog(@"\nurl: %@\ncookie: %@", req.URL, cookie);
[[NSHTTPCookieStorage sharedHTTPCookieStorage] setCookie:cookie];

It seems that there is a problem when using NSHTTPCookieOriginURL with your request's URL.

Try using this code, it worked for me :

// add cookie
    NSDictionary *properties = [NSDictionary dictionaryWithObjectsAndKeys:
                                req.URL.host, NSHTTPCookieDomain,
                                req.URL.path, NSHTTPCookiePath,
                                @"MLSTORAGE", NSHTTPCookieName,
                                @"1234567890", NSHTTPCookieValue,
                                nil];
    NSHTTPCookie *cookie = [NSHTTPCookie cookieWithProperties:properties];
    NSLog(@"\nurl: %@\ncookie: %@", req.URL, cookie);
    [[NSHTTPCookieStorage sharedHTTPCookieStorage] setCookie:cookie];
    //

However, I don't know why NSHTTPCookieOriginURL doesn't work here.

Hope this helps,

To successfully create a cookie, you must provide values for (at least) the NSHTTPCookiePath, NSHTTPCookieName, and NSHTTPCookieValue keys, and either the NSHTTPCookieOriginURL key or the NSHTTPCookieDomain key.
