Việc mua hàng trong ứng dụng của tôi hoạt động. Tôi trình bày một ModalView với một "Mua" UIButton. Bạn bấm vào nút và trong ứng dụng mua đi qua quá trình này. Bạn thậm chí có thể làm điều đó nhiều lần liên tiếp.Khi gặp sự cố khi mua ứng dụng trên [[SKPaymentQueue defaultQueue] addPayment: payment]
Sự cố xảy ra nếu bạn mở Chế độ xem phương thức, sau đó đóng Chế độ xem phương thức (sử dụng UITabBarButtonItem), sau đó mở lại Chế độ xem phương thức và nhấn vào nút "Mua". Các tai nạn ứng dụng và tôi nhận được một NSZombie mà đọc
*** - [InAppPurchaseManager respondsToSelector:]: tin nhắn gửi đến dụ deallocated 0x1c7ad0
Những điểm NSZombie để dòng 160 trong file .m . Tôi đã đánh dấu nó bằng các bình luận.
Tôi đã nhận mã gốc từ trang này: http://troybrant.net/blog/2010/01/in-app-purchases-a-full-walkthrough/
Tôi đã đấu tranh với điều này trong nhiều ngày nay ... bất kỳ trợ giúp sẽ là tuyệt vời.
