Hello Ivanhoe,

apply the following changes to the StockList Demo app in the StockListViewController class file:

- add the following lines at the very beginning of the infoTapped method:

if (!_tableKey)
[self subscribeItems];
return;

- add the following lines at the very beginning of the statusTapped method:

if (_tableKey)
[self unsubscribeItems];
return;

Now run the app and verify that pressing the status button (the green sphere) will stop the subscription, and pressing the info button will restart it. You can stop and restart it how many times you want.

Best regards,

Gianluca
