how to disable a navigation bar button item in iOS

Question

I have created a navigation controller. In the second view (which is pushed), I have some webservice call and placing a overlay view and setting

self.view.use

Answer 1

Try this code:

UIApplication.sharedApplication().beginIgnoringInteractionEvents()

This will stop user to interaction with app and after service call, write this code again:

UIApplication.sharedApplication().endIgnoringInteractionEvents()

Sure this will help.
