Typo on null check

[CrosswiredStudios]

                if (!ActionButton.Hidden && ActionButton.Title(UIControlState.Normal) != String.Empty && *ActionButton* != null)
                {
                    ActionBlock(this);
                    DismissAnimated(true);
                }

should be

                if (!ActionButton.Hidden && ActionButton.Title(UIControlState.Normal) != String.Empty && *ActionBlock* != null)
                {
                    ActionBlock(this);
                    DismissAnimated(true);
                }

or use
ActionBlock?.Invoke(this)
