      [alertView show]
  }

推荐答案

是的，很奇怪.

但是从iOS 8开始，我建议使用UIAlertController而不是UIAlertView.

But since iOS 8, I suggest to use the UIAlertController instead of UIAlertView.

用以下代码替换您的代码:

Replace your code with this one:

- (IBAction)MethodShowAlert:(id)sender
{

    [tmptxtField resignFirstResponder];

    UIAlertController * alertController = [UIAlertController alertControllerWithTitle:@"Check Alert textField"
                                                                              message:@"keyboard should not be open"
                                                                       preferredStyle:UIAlertControllerStyleAlert];

    UIAlertAction * cancelAction = [UIAlertAction actionWithTitle:@"Cancel"
                                                            style:UIAlertActionStyleDefault
                                                          handler:^(UIAlertAction *action) {
                                                              [self showCustomAlertWithTitle:@"Now Check"];
                                                          }];

    [alertController addAction:cancelAction];

    [self presentViewController:alertController animated:YES completion:nil];
}


-(void)showCustomAlertWithTitle:(NSString *)title{

    UIAlertController * alertController = [UIAlertController alertControllerWithTitle:title
                                                                              message:nil
                                                                       preferredStyle:UIAlertControllerStyleAlert];

    [self presentViewController:alertController animated:YES completion:nil];
}

单击按钮后，键盘将不会显示.

The keyboard will not show after the click on the button.
