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

Time spent: 30 hours spent in total

The following required functionality is completed:

• [x] User can sign up to create a new account using Parse authentication

• [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 load more posts once he or she reaches the bottom of the feed using infinite Scrolling
• [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:

• [x] User Profiles:
  • [x] Allow the logged in user to add a profile photo

• [x] 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

The following additional features are implemented:

• [x] Images are downloaded in a bulk, so it is not necessary to re-download every time a cell is rendered, saving data usage. (Like in the original Instagram)
• [x] Custom animations for navigating through views
• [x] Lots of UI customization and polish

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. Proper navigation using modals, I noticed that old views kept stacking up in my RAM as I used modal transitions.
2. Push notifications - how to.

Here's a walkthrough of implemented user stories:

.gifs were not working (probably they were too long), so I uploaded a video to youtube: https://youtu.be/B_M15vaXlks

GIF created with LiceCap.

List an 3rd party libraries, icons, graphics, or other assets you used in your app.

• AFNetworking - networking task library
• ElasticTransition - cool animations
• Hexacon - apple watch style collection view

I struggled a lot getting the modal transitions to work properly, I learned that going away completely from push ones is not a great thing.
