The Challenge

During the course of the development of Pop’n Or Not, we faced the following two challenges:

To prohibit any person outside the city where event is taking place to rate an event in the city

App must send a notification as soon as the rating from a predefined number of users reaches a threshold level

The Solution

To avoid unsolicited ratings, we set a virtual perimeter across every city by means of geofencing. An app user must be in the same city the event is or the app won’t let him rate an event there.

For animating the heart beat effect and making it proportional to the event rating, we used core animations: CA Spring Animation and CA Shape Animation with Bezier path

To make sure the app raises a notification upon fulfilling of those two events, we had to create a complex algorithm with many lines of code and embed it in the main code block.
