UIToolBar is not shown when adding the same toolbar as inputAccessaryView

Question

I have got a uipickerview which will be populated when pressing a uibutton. This uipickerview has a uitoolbar control in the top of the uipickerview. That tool bar has got uibuttons in it.It is working fine until i do the below thing.

I want to have that uittoolbar, on top of the uikeyboard.So I have added , that uitoolbar control as InputAccessoryView. When i did this, the uitoolbar comes with uikeyboard.that is fine.

but when i tap on the button, which has to show the uipickerview with that toolbar and also needs to resign the toolbar.

So when tap on the button, i have resigned the uikeyboard. the uipickerview is showing but the toolbar is not visible.

I have been trying to fix this for a long time, but really facing a tough time.

Please let me know.
