Tip$Cal is a tip calculator application for iOS.
Submitted by: Devon Maguire
Time spent: 10 hours spent in total
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)
- 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:
- Users can change what percentages are displayed in the segmented control options.
Here's a walkthrough of implemented user stories:

Describe any challenges encountered while building the app. The biggest challenge was my lack of knowledge of the language. For almost everything I had to do a bit of research to find out what code to use to get the application to do what I wanted it to. There were a couple of issues that took more searching to find. One was getting element of the UI to match the colorscheme, as some things could be manipulated using the custom toolbar in xcode while others had to be altered progmatically. Another was the NSDefault library and checking for nil.
