Animating Progress

01 Mar 2015

More progress of sorts, and getting close to having a beta release ready for testing.

Animation in Swift

I wanted the progress to dynamically slide in when the progress bar was shown, and this was done pretty easily using a standard CABasicAnimation on the “strokeEnd” of drawing the line. The code needed to be refactored a little to use layers instead of straight drawing of the line, but again nothing really of interest to show (so looking at the code is clearest if you’re interested)

I tried adding Facebook’s lovely Pop Animation framework, but this was very problematic as it’s an Objective-C library. I nearly got it working before giving up, but will definitely post more on this subject when I try again later.

Other bits and pieces

I also added a swipe left gesture to go from the main screen to the settings, made a simple logo and also added the percentage done to the today widget - I’ve been using the app this week as I’ve started a new contract which has been helpful to improve the interactions.

Next steps

Unfortunately it looks like there is a bug in the “weekdays only” calculations. I have a unit test to prove it, so need to fix this before I’m happy to send out for testing.
