What is actually happening that causes this warning? Im struggle to understand this.
Snapshotting a view that has not been rendered results in an empty snapshot. I pressed the hardware menu button and this warning was printed.
Actually, is it a warning? Or can it be ignored?
I am using Xcode6 and iOS8. There was no problem in iOS7.

25,475 PointsThanks Jean-Marie.
Is there a solution for this?

4,954 PointsCould you provide more details about your code and what it s going on in your code when you press the button ? What do you call the "menu button" ? is this the "home button " ?
What You should try is to put a delay for the second view to appear.
Graham Connolly
25,475 PointsYes the menu button is the hardware circular button on the device, not within the app.
If I launch my app and press the hardware menu button on the device, there is no message, but if I launch the app, and then press it again it appears.
I am using a library called RESideMenu which provides a side menu. My root view controller appears first, there is a button to segue to the second screen.
The message only appears on the seconds screen when I do the following. 1) Launch app 2) Close app 3) launch app 4) close app
Produces console message

4,954 PointsI think the side menu has an animation that interact with the appearance of the second screen or something like that. Did you tried to put a delay ?
Graham Connolly
25,475 PointsThanks for the reply again. Where would you suggest I place the delay? When performing the segue to the second view controller?
I cant really add a delay to the hardware menu button on the device.
