有没有办法在一段时间后解散uialertview？

Question

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

我想在展示一段时间后将其显示在Alerview之后 -dismissWithClickedButtonIndex:animated: method和-performSelector:withObject:afterDelay:还有其他方法可以驳回它吗？感谢您的任何想法！

Answer 1

-(void)xx  {
     [self performSelector:@selector(dismissAlertView:) withObject:alertView afterDelay:2];
}
-(void)dismissAlertView:(UIAlertView *)alertView{
    [alertView dismissWithClickedButtonIndex:0 animated:YES];
}

就是这样。我解决了

使用10秒的延误来解散

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
    }];
});

在Xamarin.ios / Monotouch中，这对我有用：

private async Task ShowToast(string message, UIAlertView toast = null)
    {
        if (null == toast)
        {
            toast = new UIAlertView(null, message, null, null, null);
            toast.Show();
            await Task.Delay(2000);
            await ShowToast(message, toast);
            return;
        }

        UIView.BeginAnimations("");
        toast.Alpha = 0;
        UIView.CommitAnimations();
        toast.DismissWithClickedButtonIndex(0, true);
    }

请记住，如果从背景线程（不是主UI线程）调用异步方法，则仍然需要InvoKeonMainThread。这只是意味着您将上述方法称为这样：

 BeginInvokeOnMainThread(() =>
 {
   ShowToast(message);
 });

更新上面的答案 UIAlertView 是 deprecated 在此链接上回答

第二个功能应该像这样

-(void)dismissAlertView:(UIAlertController *)alertView{

  [alertView dismissViewControllerAnimated:YES completion:nil];
}
