Keyboard from UIAlertController dismisses with delay

Question

I'm trying to make a login dialog in UIAlertController. Here is my code:

+ (void)authorizationDialogShow
{
    __block UITextField *loginTextField;
    __block UITextField *passwordTextField;

UIAlertController *authorizationAlert = [UIAlertController alertControllerWithTitle:@"Authorization"
                                                                            message:@"Enter login and password."
                                                                     preferredStyle:UIAlertControllerStyleAlert];

[authorizationAlert addTextFieldWithConfigurationHandler:^(UITextField * _Nonnull textField) {
    loginTextField = textField;
    loginTextField.placeholder = @"Login";
}];

[authorizationAlert addTextFieldWithConfigurationHandler:^(UITextField * _Nonnull textField) {
    passwordTextField = textField;
    passwordTextField.placeholder = @"Password";
    passwordTextField.secureTextEntry = YES;
}];

[authorizationAlert addAction:[UIAlertAction actionWithTitle:@"Login"
                                                       style:UIAlertActionStyleDefault
                                                     handler:^(UIAlertAction * _Nonnull action) {
                                                         NSString *login = loginTextField.text;
                                                         NSString *password = passwordTextField.text;
                                                         [GitAuthorization startAuthorizationWithLogin:login password:password];
                                                     }]];

[authorizationAlert addAction:[UIAlertAction actionWithTitle:@"Cancel"
                                                       style:UIAlertActionStyleCancel
                                                     handler:^(UIAlertAction * _Nonnull action) {
                                                         NSLog(@"End editing");
                                                         [authorizationAlert.view endEditing:YES];
                                                         [loginTextField resignFirstResponder];
                                                         [passwordTextField resignFirstResponder];
                                                     }]];

[authorizationAlert show];
}

The problem is in cancel UIAlertAction. When I pressed this action, the keyboard dismissed with some delay. Not at the same time as UIAlertController. What's the problem?

I'm using pod FFGlobalAlertController. Here some example of this.

I have the same issue using UIAlertController. My solution is to add a category on UIAlertController and call [self.view endEditing:YES] on viewWillDisappear. Import the category in prefix.pch if it's used widely.

- (void)viewWillDisappear:(BOOL)animated{
    [super viewWillDisappear:animated];
    [self.view endEditing:YES];
}

Thank for the answer from micap. See link below for detail: iOS 8 Keyboard Dismissed delay after modal view controller is dismissed
