How can I Crash my app?

i want To crash the app if the user press close in this code

    UIAlertView *alertView = [[UIAlertView alloc] 
                              initWithTitle:@"Alert!" 
                              message:@"What To Do To You App!" 
                              delegate:self 
                              cancelButtonTitle:@"Close"
                              otherButtonTitles:@"Open In Safari",nil];



- (void)alertView:(UIAlertView *)actionSheet clickedButtonAtIndex:(NSInteger)buttonIndex {
// the user clicked one of the OK/Cancel buttons
if (buttonIndex == 1)
{
    NSLog(@"Open in Safari");
}
else
{
    NSLog(@"Close");
}
}
