Initial Commit
Implementation of a basic working tip calculator
Switch tip percent input to bounded slider, hook up calculateTip to slider change, apply AutoLayout constraints
Feature: dismiss keyboard when tip is calculated
Add app icon
Rename to "Gratituity" and set up certificate/provisioning profile
Always show keyboard, calculate tip on value change in textMealCost, add support for textMealCost clear button, remove redundant clear UIButton, cleanup code
Change variable scope where appropriate, rename variables where appropriate
Note: at this point, the app works beautifully in iPhone 5 and bigger (4 inch screen and up), but not in 3.5 inch screens
Add explanatory comment
Complete rename + updates to gitignore
