Project 3 - Instagram

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

Time spent: 15 hours spent in total

User Stories

The following required functionality is completed:

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

The following optional features are implemented:

  • 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.
  • [ X] User Profiles:
  • [ X] Allow the logged in user to add a profile photo
  • [ X] Display the profile photo with each post
  • [ X] 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.
  • [ X] Run your app on your phone and use the camera to take the photo

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 think the UI overall could be much better, but specifically the process of posting an image can be cleaner. It would be cool to have a custom camera where you can add filters and take photos on the actual instagram app, which I know is possible if I had more time to work on it.
  2. Another thing that I would have liked to explore had we had more time is adding a location. I've always wondered how the location posting works from the backend so it would be cool to incorporate it into my project.

Notes

There were MANY challenges with this program. I think the hardest part was figuring out how to query and transfer data between view controllers so that every part of the app shares the same information about a user and about a post. The more frustrating part, though, was that most of the bugs that took me the longest to solve were not even major conceptual errors, rather, they were missing a simple line or forgetting an outlet or something. I think this is why it's so helpful to be working with peers who are able to catch errors that you did not pick up on!
