iOS Tip Calculator is a tip calculator application for iOS with customizable default settings.
Author: Jenna Vuong
Time spent: 8 hours spent total
The following required functionality is complete:
- [ x ] User can enter a bill amount, choose a tip percentage, and see the tip and total values.
- [ x ] 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)
- Using locale-specific currency and currency thousands separators.
- 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 following additional features are implemented:
- List anything else that you can get done to improve the app functionality!
Here's a walkthrough of implemented user stories:

Had trouble navigating from ViewController.swift (Tip View) to SettingsViewController.swift, exception stopped program flow. Specific error was:
'NSUnknownKeyException', reason: '[<UIViewController 0x3927310> setValue:forUndefinedKey:]: this class is not key value coding-compliant for the key defaultTip.'
Googled & realized it was the outlets for SettingsViewController.swift. Deleted unnecessary defaultTip outlet from Connections Inspector and navigation worked perfectly. Will need to figure out how to properly try catch exceptions.
