I'm new to iOS app development / Objective C and I'm trying to add a component to the app underneath the temp / pres / humd bars. This component has to change based on the sensor data but I'm having trouble accessing the component.
I can access the sensor data from classes such as the ViewController, but then I can't change the component because I can't make it as a property in the ViewController.h. I can't create the component as a property in any class other than the GaugeViewController, but then I can't access sensor data from the GaugeViewController.
Any tips on how to go about this?
