问题 I'm using SpriteKit for my iOS app, and need some full-screen (or sometimes called "interstitial" iAds to pop up every so often. I can figure out the code for when it happens, but I need to know how to add iAds without necessarily changing the View Controller.

Well, I tried this, but whenever transitioning back from the iAd view controller to the GameViewController,

问题 This question already has an answer here : How can I use a variable from another Controller in JavaFX (1 answer) Closed 6 years ago . I have one button in one FXML and two text fields in another FXML. These two FXMLs are independent, I mean they are not nested.
