A simpler Twitter client for iOS

Time spent week 1: 33 hours
Time spent week 2: 20 hours

The following required functionality is completed:

• User can sign in using OAuth login flow
• The current signed in user will be persisted across restarts
• User can view last 20 tweets from their home timeline
• In the home timeline, user can view tweet with the user profile picture, username, tweet text, and timestamp.
• User can pull to refresh
• User can compose a new tweet by tapping on a compose button.
• User can tap on a tweet to view it, with controls to retweet, favorite, and reply.

• Hamburger menu reveals by dragging anywhere on the screen.
• Hamburger reveals links to several timelines
• Profile page with header view, user stats, and user's tweets
• Tap on any profile pic in the home timeline to go to that user's profile page

The following optional features are implemented:

• When composing, you should have a countdown in the upper right for the tweet limit.
• After creating a new tweet, a user should be able to view it in the timeline immediately without refetching the timeline from the network.
• Retweeting and favoriting should increment the retweet and favorite count.
• User should be able to unretweet and unfavorite and should decrement the retweet and favorite count.
• Replies should be prefixed with the username and the reply_id should be set when posting the tweet.
• User can load more tweets once they reach the bottom of the feed using infinite loading similar to the actual Twitter client.

• Fancy profile page effects like blurring and resizing the background banner image when panning
• Allow user to switch between accounts
• Allow user to add an account, or swipe to delete an account

The following additional features are implemented:

• Timestamps are displayed with relative date formatting
• Label retweets and display the original tweet as primary in a RT, in both Home timeline and Detail screen
• Button to easily return to the top
• Compose page has placeholder text to encourage text entry
• Countdown label turns red within 20 characters of limit
• Enable buttons in timeline for each tweet cell to retweet, favorite, and reply.

• Tap on any profile pic in any timeline to go to that user's profile page
• Add "Follow" button to profile page views of users who are not the logged in user
• If user is already following the profile being displayed, change "Follow" button appearance and allow user to unfollow the profile
• Make "jump to top" button slowing appear (alpha 0 -> 1) as you scroll down the timeline
• Display hyperlinks, mentions, and hashtags in blue
• Display media in a tweet detail view

Here's a walkthrough of implemented user stories:

Much of the time during this second week was spent on refactoring to make for more efficient code (reduce duplication, increase encapsulation, make code more readable). I implemented each feature 2-3 times because I would implement it naively or inefficiently first just to get it working, then I would refactor it to reuse existing code or existing viewcontrollers and views.

The foundation for displaying entities is in there, but I haven't completed the translation of entities into hyperlinks or rich media display yet. This will be on the backlog for a post-bootcamp sprint.
