在应用程序购买代码测试期间崩溃 [英] In App Purchase Code Crashing during testing
本文介绍了在应用程序购买代码测试期间崩溃的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
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崩溃，说明无法识别的选择器已发送到实例。
I have added InApp Purchasing to my app but when trying to complete a test transaction using a Test User account, the app keeps crashing at the following code saying that Unrecognised Selector sent to Instance.
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。
I have read up about this and feel it may be something to do with the fact I am using Auto Renewal Subscription product.
似乎是代码与崩溃相关的是这一行：
The code that seems to be related to the crash is this line:
[[NSNotificationCenter defaultCenter] postNotificationName:@"TransCancel" object: self];
我已经提供了我的InAppPurchase代码，任何人都可以请它帮助我！

我是在用户进行购买的视图中使用@TransCancel，代码如下：
I am using the @TransCancel in the view that the user makes the purchase in, the code is like this:
//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;

推荐答案
你有这一行： / p>
You have this line:
[center addObserver: self selector: @selector(TransactionCancel) name:@"TransCancel" object: nil];
这意味着 self 必须实现 TransactionCancel 方法。该错误表明该方法在 MyViewController 类中不存在。
Which means that self must implement the TransactionCancel method. The error indicates that the method doesn't exist on the MyViewController class.
解决方案是添加 TransactionCancel MyViewController 类的方法。
The solution is to add the TransactionCancel method to the MyViewController class.
