René's URL Explorer Experiment

{"@context":"https://schema.org","@type":"DiscussionForumPosting","headline":"Project Feedback!","articleBody":"Nice work! This week, we continued to explore how to build apps that use an API (like Twitter). Unlike the movies app, we created a new class called TwitterAPICaller to help us interact with the API. We're also starting to introduce Auto Layout, which is how you make your app work for different phone sizes. Now that you've finished the app for the week, it's good to reflect on a few things:\r\n\r\n- Manual segue for the login button. Remember that we couldn't create a segue directly from the login button because we have to check the user's credentials. If they enter the wrong password (or the login fails), you don't want to segue to the next screen.\r\n- UserDefaults. We used UserDefaults to keep track of whether the user was logged in or not. If they were already logged in, we went directly to the tweets screen. UserDefaults is a great place to keep track of things you want to save locally, but not save on the server. For example, if you want to show a popup message one time only, you could use UserDefaults to keep track of whether you've shown the popup message already.\r\n- TwitterAPICaller. Go back to the project and look through this file that we provided. There are some functions related to authentication that you can ignore. Twitter uses OAuth 1.0a for authentication, which is an old standard. Most new APIs will use something similar to OAuth 2. Other than the authentication functions, the class is pretty simple, and you can create something similar to interact with other APIs.\r\n\r\nCheck out the [assignment grading page](hhttps://courses.codepath.org/snippets/ios_university/grading) for a breakdown of how submissions are scored.\r\n\r\nIf you have any technical questions about the project or concepts covered this week, post a question on our [Discussions Forum](https://discussions.codepath.org) and mark the question as type, \"Curiosity\".
