in-app-purchase

问题 I created an app that gives the user 3 coins at the first launch. Once the user finished the 3 coins he should buy unlimited coins by an In-App purchase. The problem is that if the user doesn't want to buy unlimited coins he can delete the app, install the app again and he will have again the 3 coins again. And he can do this forever without ever buying the In-App purchase. Is there a simple way to prevent this? How can I know if a user finished the coins inside the app even after deleting it

问题 Pretty much what the title says. The code works fine for all my development devices in the sandbox environment and for a majority of my users. However, there are some users reporting that the download process doesn't move beyond the waiting state (SKDownloadStateWaiting), even when left through the night.

问题 I have a product that has two different build, one for iPhone, and another one for iPad. Is it possible to unlock features via In-App purchase in both with make the playement once from one of them? 回答1: You cannot use the same ID, howerver, you can manage information about which purchases have been made by which users on your own server, and update that information every time a user buys something. You just have to check on that server which purchases have been made. 来源： https://stackoverflow

How to do the same or at least how can I remove this toast notification? 回答1: As other users have said, you cannot change the toast from the Play Store.

问题 I have written my code for an In-App Purchase to remove ads and it works flawlessly, except, it only works on the view controller where I removed my ads from. I want it to carry over throughout my whole app. How would I do that? Better understanding : I have Ads on a few view controllers in my app. I have a Information view controller where you can purchase the removal of ads. The thing is : it does't carry over to my other views, as if I go back to the menu view controller. Also, when I go
