Unable to change UIInputView height

Question

I have a simple UIInputViewController subclass with only two overridden methods. I use this input view controller as inputAccessoryViewController on my UIViewContro

I don't know if this is the issue, but the problem may come from the 0.0 multiplier you are setting on _heightConstraint. Try to change it to 1.0.

It would look like this:

NSLayoutConstraint *_heightConstraint = 
    [NSLayoutConstraint constraintWithItem:self.view
                                 attribute:NSLayoutAttributeHeight
                                 relatedBy:NSLayoutRelationEqual
                                    toItem:nil
                                 attribute:NSLayoutAttributeNotAnAttribute
                                 multiplier:1.0
                                   constant: _expandedHeight];

Hope this helps!
