I use this code to check for internet when the app opens for the first time:
//No Internet Connection error code
-(void)webView:(UIWebView *)webVIEW didFailLoadWithError:(NSError *)error {
UIAlertView *alert = [[UIAlertView alloc] initWithTitle:@"No Internet Connection!" message:@"In order to use this app you need an active Internet connection!" delegate:self cancelButtonTitle:@"Close" otherButtonTitles:nil, nil];
[alert show];
}
//Close app from Alert View
- (void)alertView:(UIAlertView *)alertView didDismissWithButtonIndex:(NSInteger)buttonIndex {
exit(0);
}
I have a UIWebView app that has a jQuery .click() function. Is there a way to check for Internet again once the user clicks that button?
Take a look at Apple's sample code. The Reachability project shows how to detect a connection
