How to handle “Turn ON Location Alert” on Calendar

Question

Steps to produce this issue of iOS Calendar App. (for this issue you must have already 'Allow' location service for calendar app)

1) Go To Settings 2) Turn Off Location services 3) Go To Calendar App 4) Add New Event 5) Select Location to enter You will see "Turn ON Location Services To Allow....." Alert with "Settings" and "Cancel" buttons. But alert will get disappear in 1-2 seconds and app displays Location search screen.
