Pre-work - Tipi

Tipi is a tip calculator application for iOS.

Submitted by: Usman Ajmal

Time spent: 8 hours spent in total (while some serious people-watching at coffee-shop)

User Stories

The following required functionality is complete:

  • User can enter a bill amount, choose a tip percentage, and see the tip and total values.
  • Settings page to change the default tip percentage.

The following optional features are implemented:

  • UI animations
  • Remembering the bill amount across app restarts (if <10mins)
  • Making sure the keyboard is always visible and the bill amount is always the first responder. This way the user doesn't have to tap anywhere to use this app. Just launch the app and start typing.
  • The Tip calculator has a very primitive UI. Feel free to play with colors, layout, or even modify the UI to improve it.
  • Using locale-specific currency and currency thousands separators.
  • Add a light/dark color theme

The following additional features are implemented:

  • Feature for splitting the total amount between 2,3 and 4 people

Video Walkthrough

Here's a walkthrough of implemented user stories:

Notes

  • I wasn't able to use NSDate. Used NSTimer for the timer functionality
  • Had trouble with solving a warning related to usage of #selector instead of creatin a new selector but figured it out finally.
  • Had trouble sometimes with navigating between files in Xcode sometimes
  • Couldn't define static array for tip percentages
