Close app when internet is not available

Question

I want to close my app when an Internet connection is not available.

I check that, but how can I create an alert, and then close my app?

Answer 1

Instead of closing it, consider explaining the situation to the user by the means of a popup.

First of all, download Reachability from Apple.

Add the classes Reachability.h,.m,delegates to your project. Then in your .m class import Reachability

#import "Reachability.h"

And in viewWillAppear or when you should display the alert:

//Connection check
    Reachability *reach = [Reachability reachabilityForInternetConnection]; 
    NetworkStatus netStatus = [reach currentReachabilityStatus];    
    if (netStatus == NotReachable)
    {   
        UIAlertView * alert = [[UIAlertView alloc] initWithTitle:@"No Internet Connection" message:@"Explain the situation to the user" delegate:nil cancelButtonTitle:nil otherButtonTitles:@"Ok", nil];
        [alert show];
        [alert release];       

    }    
    else {
    //other actions.
    }

As others said before me.
