Our app uses a custom input view, added as a subview to an instance of UIInputView. We're receiving crash reports after adding this view to our UITextView's inputView property and then calling [textView reloadInputViews], but I can't reproduce the crash.
Are we going about this the wrong way, or is something else going on here?
Here's an excerpt of our crash log:
