我已将InApp Purchasing添加到我的应用中，但在尝试使用测试用户帐户完成测试事务时，应用程序会在以下代码中继续崩溃，说明发送到实例的无法识别的选择器。
我已经阅读了这篇文章，并认为这可能与我使用Auto Renewal Subscription产品的事实有关。
似乎与崩溃有关的代码就是这一行：
[[NSNotificationCenter defaultCenter] postNotificationName:@"TransCancel" object: self];
我已经提供了我的InAppPurchase代码，任何人都可以请你帮我这个!!

我在用户进行购买的视图中使用@TransCancel，代码如下：
//购买
NSNotificationCenter *center = [NSNotificationCenter defaultCenter];
[center addObserver: self selector: @selector(TransactionCancel) name:@"TransCancel" object: nil];
[center addObserver: self selector: @selector(TransactionComplete) name:@"successbuy" object: nil];
NSLog(@"%d",[[NSUserDefaults standardUserDefaults] boolForKey:@"PurchaseSuccess"]);
if([[NSUserDefaults standardUserDefaults] boolForKey:@"PurchaseSuccess"])
btn.hidden=YES;
else
btn.hidden=NO;

答案 0 :(得分：0)
你有这一行：
[center addObserver: self selector: @selector(TransactionCancel) name:@"TransCancel" object: nil];
这意味着self必须实施TransactionCancel方法。该错误表示该方法在MyViewController类中不存在。
解决方案是将TransactionCancel方法添加到MyViewController类。
