Back again with another episode, this time we'll go into the depths of integrating Twitter Login into our application. We'll first start with getting a Fabric account at https://get.fabric.io. Then we can start installing the Twitter pods by configuring our pod file appropriately. Finally we'll integrate the TWTLoginButton along with getting the application to authenticate our user properly. Enjoy!
