Hi Gianluca!!

I really appreciate your help, you are too kind!!

The connection error, I think is gone. I haven't seen it again.

About the table view. Do you remember when I told you that I have 3 views, every one contains a table view. I know the program structure is completely wrong. But my question is, Would it be possible when I call every unsubscribe method, the _tableKey doesn't release it? maybe because it doesn't know the name of the table. I mean they have the same name "_tableKey".

I rechecked the sample of StockList .appDelegate specifically. When I push HOME it calls the method unsubscribe, but when I debugged it, it doesn't get into unsubscribe method, so I uncomment NSLog Line and it was not written in console either.

What do you think it is happening with the unsubscribe method? I can not finish to understand the way it works.

Kind Regards!!
