However, I need to be able to make the purchase much more

问题 Is it possible to implement an in-app purchase within the SKScene ? If so, how? I'm trying to use a SKSpriteNode as a 'buy' button with no luck. I'm not sure whether the code needs to go in the SKScene or the view controller. I've looked at loads of tutorials, but they all seem to be aimed at single view applications rather than in SpriteKit. 回答1: First, put this in your game scene line and make sure you have the framework 'StoreKit' imported class GameScene: SKScene,

问题 I have Apple iOS IAP successfully implemented in my app and tested in the sandbox. Works great. I'm concerned that users could buy something with IAP, download it into my app, then complain to Apple and get a refund. There's no obvious way that refunds are reported to my app. Are they simply left out of the list of products I receive during a "restore" operation? Is there some undocumented transaction type that will asynchronously show up in my SKPaymentTransactionObserver when a refund

问题 We are developing a Point of Sale app available on iOS and Android platforms. Our business model is such that, each user will have to pay us a customised cost based upon the number of his business outlets on half yearly or quarterly basis. Once the user will pay us that cost than he could use our apps on any number of devices, on any platform. I want to know if it's compulsory to process subscription charge for iOS App through Apple In App Purchases. Or we can process subscription offline and

问题 I did big mistake with monetisation my app in Google Play. I separated my app to 2 versions (with different applicationId), but now I would like to have one app with in-app purchases to Pro version or something like unlocker. I have a lot of downloads my pro version app so I can't just remove it from Google Play. Does anyone faced with this problem ? Any workarounds ? 回答1: You can definitely integrate both apps ( Search on stackoverflow for integrating both apps ), but that will not solve
