my iOS app in objective c is crashing due to the following error in Xcode 8 and Xcode 9.

error:

Cannot form weak reference to instance (0x198bfc00) of class UICompatibilityInputViewController. It is possible that this object was over-released, or is in the process of deallocation.

I am not getting any idea about this crash, pls do help me. Thanks in advance.

@3stud1ant3 please wait...will let u know the line in a while. – ABHILASH P Oct 28 '17 at 07:00
it crashes on the line textfield becomeFirstResponder – ABHILASH P Oct 28 '17 at 07:24
Please note: for those text fields i have added inputAccessoryView(for Done button). Is that an issue? – ABHILASH P Oct 28 '17 at 07:25
@ABHILASH P, how you create accessoryView?. I am guessing the property of accessory view is in local. so it does get deallocated. – Yongjoon Oct 29 '17 at 00:40
@Yongjoon I create a local instance of UIToolBar in a method and then assign that to a global textfield as textfield.inputAccessoryView = toolBar; I commented this usage and my crash got solved. But still not getting the exact reason. May be you are right. I still have confusion regarding this issue. – ABHILASH P Oct 30 '17 at 13:03
@ABHILASHP hey, if it still relevant to you check my answer here https://stackoverflow.com/a/54227163/5424020 I hope it will help somehow. Maybe you will find other pod or third part lib that the reason. – Denis Vert Jan 17 '19 at 08:57
