feature complete twitter app clone

[adamtait]

here's my complete twitter app. I spend quite a bit more time with this one than previous apps and I think it really paid off. I'm mostly happy with the results and I know I'm way more comfortable with layouts & constraints than I was before. In hindsight, I could have used interface builder more (I only have 2 xib's), but layouts without interface builder have their benefits, too (see my ADRs).

Additions I'd still like to make:

• The missing killer feature really is the clickable links. I use twitter mostly as a news source and without clickable links, I can't do that.
• Network errors could be handled better. The app should sign out the user, and notify them. At the very least, favorites & retweets should not appear active.
• on pull to refresh, I'm reloading all the tweets. This is both slow and destroys the cache of the tweets that have built up from infinite scrolling.

Great work, Adam!

• If you implement views programatically, you should build the views in the loadView method.
• It's more common to use - (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath
• Your tweet detail view has a clear background, which is why there's a weird effect when the view is transitioning.

The point of this homework was to explore some challenges involved in developing a richer MVC client. Below is the checklist I went through when reviewing your application.

• Did you create a custom Tweet cell and properly set up Auto Layout constraints?
• Did you augment the User and Tweet model with the required properties?
• Date parsing and formatting is expensive, so consider caching in models when you can.
• Does tapping on a Tweet take you to a detailed Tweet view?
• Is the detailed Tweet view styled like the mock?
• Did you add both standard and retina (@2x) image assets? A new feature of XCode is to use the Images.xcassets, it makes it easier to handle the standard and retina assets. If you only included standard assets, it will be scaled for retina displays which makes them a little blurry.
• Does tapping on retweet and favorite increment the retweet and favorite count? If I go back to the index and tap on the same tweet again, is the tweet still marked as retweeted or favorited with the correct count?
• Does the compose view restrict the number of Twitter characters?
