iOS UIAlertView button to go to Setting App

Question

Is there a way to have the button of a UIAlertView go to the Settings App for the specific App calling it?

Thanks

Answer 1

Apparently, this does not work in iOS 5.1 whatsoever. I have been fighting it all morning, and then ran across this blog

Opening settings apps programmatically is possible only from iOS 8. So, use the following code...

if([CLLocationManager locationServicesEnabled]&&
   [CLLocationManager authorizationStatus] != kCLAuthorizationStatusDenied)
{
  //...Location service is enabled
}
else
{
    if([[[UIDevice currentDevice] systemVersion] floatValue]<8.0)
    {
    UIAlertView* curr1=[[UIAlertView alloc] initWithTitle:@"This app does not have access to Location service" message:@"You can enable access in Settings->Privacy->Location->Location Services" delegate:self cancelButtonTitle:@"OK" otherButtonTitles:nil, nil];
    [curr1 show];
    }
    else
    {
        UIAlertView* curr2=[[UIAlertView alloc] initWithTitle:@"This app does not have access to Location service" message:@"You can enable access in Settings->Privacy->Location->Location Services" delegate:self cancelButtonTitle:@"OK" otherButtonTitles:@"Settings", nil];
        curr2.tag=121;
        [curr2 show];
    }
}

- (void)alertView:(UIAlertView *)alertView clickedButtonAtIndex:(NSInteger)buttonIndex
{
 NSLog(@"buttonIndex:%d",buttonIndex);

   if (alertView.tag == 121 && buttonIndex == 1)
 {
  //code for opening settings app in iOS 8
   [[UIApplication sharedApplication] openURL:[NSURL  URLWithString:UIApplicationOpenSettingsURLString]];
 }
}

It works on iOS8+ also,but we need to change something

NSURL*url=[NSURL URLWithString:@"prefs:root=WIFI"];
if([[UIApplication sharedApplication] canOpenURL:url]){
    [[UIApplication sharedApplication] openURL:url];
}

For example:

NSURL*url=[NSURL URLWithString:@"prefs:root=WIFI"];
[[UIApplication sharedApplication] openURL:url];
