iOS Question Error when trying to provide ratings from within my app

[jo1234]

Hi,

I'm trying to use this code to allow users to provide ratings from within my app.

If App.OSVersion >= 10.3 Then
     Dim no As NativeObject
     no.Initialize("SKStoreReviewController").RunMethod("requestReview", Null)
End If

However, I get an error on iOS12:

Error in line of "no.Initialize("SKStoreReviewController").RunMethod("requestReview", Null)"
Object was not initialized (NSObject)

How can I fix this?

Thanks a lot,

Are you testing it on a real device?

 

[jo1234]

Yes, in debug mode on iPhone 6.
It worked a week ago, now I tested again and got the error.

Try to add this line:

#AdditionalLib: StoreKit.framework

Clean the project and run again.
