Is there a way to dismiss an no button UIalertView after some time?

Question

UIAlertView *alertView = [[UIAlertView alloc] initWithTitle:@"tittle"
               message:@""
                 delegate:self
              cancelButtonTitle:@""
              otherButtonTitles:nil];

    [alertView dismissWithClickedButtonIndex:0 animated:YES];
}

Answer 2

Use 10 seconds delays to dismiss

UIAlertController *alertController = [UIAlertController alertControllerWithTitle:@"" message:@"" preferredStyle:UIAlertControllerStyleAlert];
[self presentViewController:alertController animated:YES completion:nil];

dispatch_after(dispatch_time(DISPATCH_TIME_NOW, (int64_t)(10.0 * NSEC_PER_SEC)), dispatch_get_main_queue(), ^{
    [alertController dismissViewControllerAnimated:YES completion:^{
        p\Perform Action after dismiss alertViewController
    }];
});
