      [alertView show]
  }

Answer 1

In my case i tried hiding keyboard, before showing alert, so it will not save keyboard in memory to present it again after dismissing it self.

for that you just need to dismiss keyboard which will take default animation time to hide, only then you should present alert view then it will not save that keyboard.

you must put around .6 second gap in hiding keyboard and presenting alert

  [YOUR_TEXT resignFirstResponder];
            dispatch_after(dispatch_time(DISPATCH_TIME_NOW, (int64_t)(.6 * NSEC_PER_SEC)), dispatch_get_main_queue(), ^{


                    _alertVw = [[UIAlertView alloc] initWithTitle:@"" message:@"message." delegate:self cancelButtonTitle:@"Ok" otherButtonTitles:nil, nil];

                    [_alertVw show];
});

Yep, it's strange.

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

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];
}

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