Question

I’m pretty new to iPhone development and I’m still getting my head around Objective-C, so please bear with me 🙂

I am trying to change the text of a label from inside an object that belongs to the main view controller. Umm. I think that sounds right.

For those of you familiar with the AQRecorder class from the SpeakHere example on the iPhone Reference Library: –

I am trying to update a label every time AQRecorder::MyInputBufferHandler is called (i.e. when the input buffers have been filled)

My first approach was to modify the AQRecorder class to contain a UILabel* that I send as a parameter to the modified constructor. It worked, but it felt very wrong. And now that I want to modify a couple of different UI components I was hoping there’s a better way.

I’ve got a feeling that I’m missing something basic. That or I’m going to require a bit of refactoring.

Look into using NSNotificationCenter. It provides decoupled notifications, so the recorder class won’t have to know anything about the UI.
