Unbalanced calls to UIViewController when asking for HealthKit permissions

I ask my user for permission to HealthKit by allowing the user to click a button 'Connect to Health App'.

This calls the [HKStore requestAuthorizationToShareTypes:...] function which will ultimately present a view controller modally for the user to configure the various permissions.

Doing this leads to the error "Unbalanced calls to begin/end appearance transitions for UIViewController:"

I have tried using [performSelector withDelay] in the event handler of the button to a separate function which then in turn calls HealthKit ie. in order to allow the button pressing animation to complete before a new view controller is pushed onto screen. The error persists.

Any ideas or is this a bug or is the warning harmless?

Thanks

It's a bug in iOS, not your application. It's also harmless, so don't worry about it.
