Quit iOS Application Programmatically with UIAlertView

Question

I'm aborting my iOS Application by below methods

-(void)cancelSelected
{
    UIAlertView * alert = [[UIAlertView alloc] initWithTitle:nil message:@"Are you sure you want to exit?" delegate:self cancelButtonTitle:@"No" otherButtonTitles:@"Yes", nil];

    [alert show];

    alert = nil;
}

Method 1 :

-(void)alertView:(UIAlertView *)alertView clickedButtonAtIndex:(NSInteger)buttonIndex
{
    if (buttonIndex)
        abort();
}

Method 2 :

-(void)alertView:(UIAlertView *)alertView clickedButtonAtIndex:(NSInteger)buttonIndex
{
    if (buttonIndex)
        [NSException raise:@"Disagree terms and conditions." format:@"Quit, Cancel"];
}

Shall I do this to quit my iOS Application programmatically?

Will this abort() method leads to reject my app?

Thanks!

See QA1561:

Q: How do I programmatically quit my iOS application?

A: There is no API provided for gracefully terminating an iOS application.

In iOS, 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.
