Can Iphone restore the state of app after [[UIApplication sharedApplication] openURL:[NSURL URLWithString:call_url]];

Question

In my Iphone app I give a button when pressed calls a specific number using the following function call and uses the native iphone call app.

[[UIApplication sharedApplication] openURL:[NSURL URLWithString:call_url]]; where call_url is of the form tel://

Once the call is done, is there a way to restore and open my Iphone App as it was before calling ?

Answer 1

No. Your process has been terminated. You'll have to depend on the user to start your app again and you have to restore the state yourself.

Answer 2

You can set your app to save its state before it calls the URL. Use the iPhone Sample code DrillDownSave as an example
