In my app I am streaming audio and there is a period of 5-10 sec depending on the connection where the buffer is loading and after this, my app starts to play the audio. When it starts to play the audio this symbol comes up in the screen.
Here is an image of what im talking about.

I want to change a label in my app when this symbol comes up in the screen, but i dont know which function let me detect this.
The symbol is the "Play" button common to music devices. There is most likely an NSNotification center message that can be "listened for". However, depending on how you are buffering your sounds there is probably a delegate that can notify a selector once it has begun playback. Without more details I can not give more detailed advice. If I were in your position I would take a very hard look at the API you are utilizing, most likely several methods exist to either post notification or send delegate messages notifying the state of the stream as well as playback. I have worked with some streaming audio API and I was able to get status of the buffer as well many other messages from the stream object(s). These are just part of good design, so most likely it is there.
