instagram's Introduction

Project 4 - Instagram

Instagram is a photo sharing app using Parse as its backend.

Time spent: 50 hours spent in total

User Stories

The following required functionality is completed:

  • User can sign up to create a new account using Parse authentication
  • User can log in and log out of his or her account
  • The current signed in user is persisted across app restarts
  • User can take a photo, add a caption, and post it to "Instagram"
  • User can view the last 20 posts submitted to "Instagram"
  • User can pull to refresh the last 20 posts submitted to "Instagram"
  • User can tap a post to view post details, including timestamp and caption.

The following optional features are implemented:

  • Run your app on your phone and use the camera to take the photo
  • Style the login page to look like the real Instagram login page.
  • Style the feed to look like the real Instagram feed.
  • User can use a tab bar to switch between all "Instagram" posts and posts published only by the user. AKA, tabs for Home Feed and Profile
  • User can load more posts once he or she reaches the bottom of the feed using infinite scrolling.
  • Show the username and creation time for each post
  • After the user submits a new post, show a progress HUD while the post is being uploaded to Parse
  • User Profiles:
    • Allow the logged in user to add a profile photo
    • Display the profile photo with each post
    • Tapping on a post's username or profile photo goes to that user's profile page
  • User can comment on a post and see all comments for each post in the post details screen.
  • User can like a post and see number of likes for each post in the post details screen.
  • Implement a custom camera view.

The following additional features are implemented:

  • In addition to changing the profile picture, user can change their first and last name
  • In addition to changing the profile picture, user can change their bio
  • User can see their updated name and bio reflected on their profile page

Please list two areas of the assignment you'd like to discuss further with your peers during the next class (examples include better ways to implement something, how to extend your app in certain ways, etc):

  1. I didn't get the chance to explore implementing the commenting feature - I think this is something that could be interesting to discuss with peers on their approach.
  2. I'd like to go more into depth with cell headers, and using these to implement the comment/username features rather than separate views.

Project Feedback!

Nice work and congrats on completing your final assignment! Parse is a great tool for quickly prototyping the backend for many apps. Even if you choose to ultimately replace Parse with a more conventional backend (e.g., Rails, Django, Node.js), that wouldn't really change the iOS code.

At this point, even though we've been building fairly simple iOS apps, we've covered a lot of the core concepts involved in iOS development. A lot of time and code in modern iOS apps is spent putting on the final 10% of polish, which is surprisingly time consuming and technically challenging. Here's a few additional topics that we didn't cover, but you should look into if you want to continue iOS development:

  • Core Data. This isn't used by Facebook and many other companies, but is still asked about in iOS interviews.
  • Multithreading. Grand Central Dispatch and NSOperationQueue.
  • Custom Views. We used custom views via pods, and eventually you'll need to make your own!
  • Custom Interactive View Controller Transitions. If you're tired of view controllers animating in from the right or from the bottom, then you'll need to implement transitions yourself.
  • Gesture recognizers. We used a few tap gesture recognizers, and you'll also commonly need to use the pan and pinch gesture recognizers.
  • Unit and integration testing. Once you're in an actual company (or earlier!), you'll need to start actually testing your code.
