Hi,

I'm having difficulties displaying data in a TextView in iPhone programming.

I'm analyzing incoming audio data (from the microphone). In order to do that, I create an object "analyzer" from my SignalAnalyzer class which performs analysis of the incoming data. What I would like to do is to display each new incoming data in a TextView in realtime.

So when I push a button, I create the object "analyzer" whiwh analyze the incoming data. Each time there is new data, I need to display it on the screen in a TextView.

My problem is that I'm getting an error because (I think) I'm trying to send a message to the parent class (the one taking care of displaying stuff in my TextView : it has a TexView instance variable linked in Interface Builder). What should I do in order to tell my parent class what it needs to display ? Or how sohould I design my classes to display automaticlally something ?

Thank you for your help.

PS : Here is my error :
