How to match beginIgnoringInteractionEvents before adding endIgnoringInteractionEvents

Question

I am using these two functions [[UIApplication sharedApplication] beginIgnoringInteractionEvents]; and [[UIApplication sharedApplication] endIgnoringInteractionEvents]; while I am downloading data from server.

I am getting below error in my log.

-[UIApplication endIgnoringInteractionEvents] called without matching -beginIgnoringInteractionEvents. Ignoring.
