iOS 12 – First Impressions
After having used the beta version of iOS 12 for the last month or so, I can tell you that whatever Apple messed up in iOS 11, they un-did in iOS 12. It’s a lot faster than its predecessor, and the battery life is back to its former glory.
Here are my thoughts about using the iOS 12 Beta on my ageing iPhone 5s.
Building a Day Counter on iOS – Part 3
In this series I’ll show you how to create a simple Day Counter on iOS, using Objective-C and Xcode 9. The idea is to set a date in a settings screen, and then see how many days have elapsed on the main screen right after launching the app.
This is a 3-Part Mini-Series:
- Part 1 is all about building the interface in Interface Builder
- Part 2 is about coding the NSDate subtraction methods, using NSCalendar and loading/saving data using NSUserDefaults
- Part 3 will introduce Key/Value Observing to update the first view controller as soon as the date is changed in the settings and deals with how to normalise an NSDate object.
You can find the full code on GitHub:
Happy Hacking!
