我相信问题就在商店中
for product in products {
print(product.productIdentifier)
if product.productIdentifier == node.userData!["Product"] as! String {
print("gototpayment")
storeManager.purchaseProduct(product: product)
coreLabelNode.text = "\(core)"
}
点击一个SKSpriteNode的一个，例如buy150将打印出来：
gottoloop 触碰 得环 gottonodename gettoprefix C1 com.AlienBeing.lightslicer.buy150 []
主要问题是它应该在沙盒环境中打开一个iTunes购买窗口，但它甚至从不访问对storeManager.purchaseProduct（product：product）的调用 因为产品数组是空的...我不知道
因为在总是立即以[]结尾的位置打印打印（产品），所以未使用正确的产品填充产品SKProduct数组。我不认为它应该为空，但填充它可能会丢失一些东西。我已经坚持了一段时间。真的可以使用一些帮助:)
我应该补充一点，我不是一个很好的程序员，或者更确切地说，我还在上大学并且还在训练自己，因此，如果有任何有益的提示可以帮助我学习更多的最佳实践，也请多多关照，谢谢向导未来。 （这真的是你们在这里所经历的，不要忘了它）
