我的应用内购买工作.我提出了一个带有"购买"UIButton的ModalView.单击该按钮,In App Purchase将完成整个过程.你甚至可以连续几次这样做.

如果您打开模态视图,然后关闭模态视图(使用UITabBarButtonItem),然后重新打开模态视图并点击"购买"按钮,则会出现此问题.该应用程序崩溃,我得到一个NSZombie读取

*** - [InAppPurchaseManager respondsToSelector:]:发送到解除分配的实例0x1c7ad0的消息

NSZombie指向.m文件中的第160行.我用评论标记了它.

我从这个页面得到了原始代码:http://troybrant.net/blog/2010/01/in-app-purchases-a-full-walkthrough/

我一直在努力奋斗很多天......任何帮助都会很棒.
