how can I hide an empty tableview

Question

I have a problem and I hope someone here can help me out! Thanks in advance.

I have a "Scope"button(see screen shot!) which is linked to a segue and the segue goes to a tableview.

What I want to do is in the tableview controller that I decide if I should display something in the table or I should throw out an alertview.

What I did was:

if ([_countryScopes count] == 0) {

    [self.view removeFromSuperview];
    //no scope for this country
    NSMutableString *message = [[NSMutableString alloc]initWithString:@"No scope information."];
    UIAlertView *av = [[UIAlertView alloc] initWithTitle:countryName message:message delegate:self cancelButtonTitle:@"Ok" otherButtonTitles:nil, nil];
    //av.tag = MAIN_ALERT;
    [av show];


}

But somehow the empty table is still showing up.

Do you know, how I can get rid of this?

Thanks a lot!

仅在0.1秒后显示警报视图，我希望这可以解决问题：

[av performSelector:@selector(show) withObject:nil afterDelay:0.1];
