So I know this is an old post and I am not sure if you resolved this or not, but I found a way to get this working. I believe there is a bug in the inputAccessoryView, but I created a hacky solution to behave the way the messages app does. I think I provided all the necessary code to implement the work around. I am going to try and get a more appropriate blog post created sometime in the near future, with a more in depth description with my findings. Any questions, let me know.

@property(nonatomic,assign)BOOL isViewAppear;
@property(nonatomic,strong)ChatBarView *chatView; //custom chat bar view
@property(nonatomic,strong)UIView *footerPadView; //just to add some nice padding
