无法使用-[NSObject（NSObject）DoesNotRecogniteSelector:]理解Apple崩溃日志

Question

这很奇怪，我可以在模拟器中运行我的应用程序，使用Xcode 5（5A1413）运行iPhone 4S和iPhone 5，没有任何问题，但当我将应用程序提交到iTunes商店时被拒绝，此日志由苹果提供。

这是我从苹果得到的信息：

我们发现你的应用程序在运行iOS 7.0的iPhone 5s上崩溃。2，这不符合应用商店审查指南。

我承认我是无知的，你能帮我理解一下这个崩溃日志吗：

Answer 1

在应用审查期间，应用收到一个EXC_CRASH（SIGABRT）异常。这意味着运行在应用程序中的代码检测到故障，因此它要求操作系统终止您的进程，这是通过SIGABRT信号完成的。

中止的起源是Object-C运行时在分派方法请求时检测到一个doesNot确认选择器问题，如异常回溯中所示

2   CoreFoundation                  0x314667b2 -[NSObject(NSObject) doesNotRecognizeSelector:] + 198

导致这种情况的代码是：

NSData *myToken = [[NSData alloc] initWithData:[[NSUserDefaults standardUserDefaults] objectForKey:HCBDeviceTokenPrefKey]];

这是因为NSData将假定用户默认具有设备令牌的NSData结果。如果未获得适当的NSData对象，它将向不知道NSData的此私有实现类的对象发送-[\u NSPlaceholderData initWithData:构造函数消息

以下测试代码通过实验证明了这一点：

NSData *myToken = [[NSData alloc] initWithData:[[NSUserDefaults standardUserDefaults] objectForKey:@"SomeKey"]];

NSLog(@"My data is %@ - ok since we can handle a nil", myToken);

id stringProperty = @"Some string";
NSData *problemToken = [[NSData alloc] initWithData:stringProperty];

NSLog(@"My data is %@ - we have probably crashed by now", problemToken);

退一步说，重要的是要了解崩溃的发生往往不是由于代码本身，而是由于代码运行的环境。

你的工作和失败案例有两个不同的因素。

1. 您的应用程序在本地可能已通过先前的运行设置，其用户默认值为NSData令牌
2. 您的应用程序本地测试可能使用的调试版本（默认配置）与您的发布版本（将发送给Apple）不同

尝试的事情：

1. 在模拟器中，擦除内容和设置，然后重试您的应用程序。
2. 在Xcode（模式设置）中，将部署版本从Debug更改为Relight。
3. 放入测试HCBUserIDPrefKey键的用户默认值类型的代码。确保它是NSData（也检查无）。
