Question

I am developing an iPhone application which is completely based on web data.

If it is not connected to the internet, the application is of no use.

So, I want to terminate the application when connection is not found.

NSURL *tmpURl=[NSURL URLWithString:[NSString stringWithFormat:@"[e-mail]",[iGolfAppDelegate getServerPath]]];
    NSMutableURLRequest *theRequest=[NSMutableURLRequest requestWithURL:tmpURl];
    con=[[NSURLConnection alloc] initWithRequest:theRequest delegate:self];
    if(con){
        myWebData=[[NSMutableData data] retain];    
    } else { 
        //Yes I will provide two buttons on alertview "retry" & "close", & when user
        //taps on "close" => application should terminate.
        // i will send alertview & when user taps on button close then
        // what to write for terminating application?
        // Ok Ok. Don't terminate. User will terminate.
        // user is owner of iPhone 
        // let him choose what to do
        // wait till wifi connects
    }

The question is how to terminate the application?

Is exit(0) only the option for terminating application or is there any other option available?

Answer 1

Apple is is absolutely clear about this topic:

There is no API provided for
gracefully terminating an iPhone
application. Under the iPhone OS, the
user presses the Home button to close
applications. Should your application
have conditions in which it cannot
provide its intended function, the
recommended approach is to display an
alert for the user that indicates the
nature of the problem and possible
actions the user could take – turning
on WiFi, enabling Location Services,
etc. Allow the user to terminate the
application at their own discretion.
