These two places often crash，I used the inputview

Any idea what's going on here? I have the exact same issue.

Same Issue. I am creating an instance of TPKeyboardAvoidingScrollView for my scroll view.

UIScrollView *scrollView = [[TPKeyboardAvoidingScrollView alloc]initWithFrame:CGRectNull];

Also, the keyboard fails to show up when the crash happens. On other views where ScrollView is not required, keyboard works fine (E.g. Search Bar in a Table View).

Error Details: Terminating app due to uncaught exception 'CALayerInvalidGeometry', reason: 'CALayer position contains NaN: [-4.25 nan]'

EDIT: My case may be a little different. I am able to reproduce it 100% on simulator. The TextField uses UIKeyboardTypeNumberPad. Use case:

1. User taps on TextField fills in the number.
2. User taps on Next Button on Navigation Bar to navigate to next view.

It does not crash for following use case:

1. User taps on TextField fills in the number.
2. User taps on scroll view. Keyboard Dismisses.
3. User taps on Next Button on Navigation Bar to navigate to next view.

Should I explicitly dismiss keyboard before navigating to next view ?

Hey @rachin-pepo - would you be able to make/adapt a sample app demonstrating this issue?
