Looked intoUIKeyboardAnimationDurationUserInfoKey but I just can't find anywhere how to set it to a custom value.

UIKeyboardAnimationDurationUserInfoKey is a const string identifier for the dictionary key that holds the animation duration, so there is no way to change it easily.

One way to make the keyboard appear without animation is to observe the keyboard notifications and disable animation when it's about to appear and then reenable them. This, of course, disables any other animation as well.

[[NSNotificationCenter defaultCenter] addObserver:self 
                                         selector:@selector(willShowKeyboard:) 
                                             name:UIKeyboardWillShowNotification 
                                           object:nil];

[[NSNotificationCenter defaultCenter] addObserver:self 
                                         selector:@selector(didShowKeyboard:) 
                                             name:UIKeyboardDidShowNotification 
                                           object:nil];

- (void)willShowKeyboard:(NSNotification *)notification {
    [UIView setAnimationsEnabled:NO];
}

- (void)didShowKeyboard:(NSNotification *)notification {
    [UIView setAnimationsEnabled:YES];
}

and then then the same for UIKeyboardWillHideNotification/UIKeyboardDidHideNotification notifications.

I've found the best solution is using UIView.setAnimationsEnabled(_ enabled: Bool).

Swift 3

UIView.setAnimationsEnabled(false)
textField.becomeFirstResponder()
// or textField.resignFirstResponder() if you want to dismiss the keyboard
UIView.setAnimationsEnabled(true)

Try

[UIView performWithoutAnimation:^{
    [textField becomeFirstResponder];
}];

The answer of @Vadoff works perfect. Here for Swift 3:

    override func viewDidLoad() {
        super.viewDidLoad()

        //...

        // Add observer to notificationCenter so that the method didShowKeyboard(_:) is called when the keyboard did show.
        NotificationCenter.default.addObserver(self, selector: #selector(type(of: self).didShowKeyboard(_:)), name: NSNotification.Name.UIKeyboardDidShow, object: nil)

        // Make textField the first responder.
        textField.becomeFirstResponder() // <- Change textField to the name of your textField.
    }

    func textFieldDidBeginEditing(_ textField: UITextField) {
        // Disable animations.
        UIView.setAnimationsEnabled(false)
    }
    func didShowKeyboard(_ notification: Notification) {
        // Enable animations.
        UIView.setAnimationsEnabled(true)
    }

It is pretty simple guys. Do not use UIView:SetAnimationEnabled as that will be potentially troublesome. This is how i remove animation when keyboard show. 

- (void)viewWillAppear:(BOOL)animated {
    [super viewWillAppear:animated];

    [txtFirstName becomeFirstResponder];
}

- (void)viewWillDisappear:(BOOL)animated {
    [super viewWillDisappear:animated];

    [txtFirstName resignFirstResponder];
}

I had to disable Animations in textViewShouldBeginEditing, textFieldDidBeginEditing did not work for me (iOS 8)

iOS8-compatible:

Add the appropriate delegate method:

- (void)textFieldDidBeginEditing:(UITextField *)textField {
    [UIView setAnimationsEnabled:NO];
}

or 

- (void)textViewDidBeginEditing:(UITextView *)textView {
    [UIView setAnimationsEnabled:NO];
}

Add the keyboard notification:

[[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(didShowKeyboard:) name:UIKeyboardDidShowNotification object:nil];

And method:

- (void)didShowKeyboard:(NSNotification *)notification {
    [UIView setAnimationsEnabled:YES];
}
