MFMailComposeViewController和SKStoreProductViewController的init方法发生iOS崩溃

我正在开发一个部署目标为7.0的iOS应用程序，并尝试在应用程序中提供内置的视图控制器，如MFMailComposeViewController和SKStoreProductViewController。但是，当我初始化任何内置视图控制器并显示以下错误消息时，我的应用程序就会崩溃：

[__NSGlobalBlock__ encodeWithCoder:]: unrecognized selector sent to instance 0x57986c

碰撞发生在以下几行：

MFMailComposeViewController* controller = [[MFMailComposeViewController alloc] init];

及

我找不到这个错误的任何线索。我正在使用一些第三方播客，如KeepLayout和ReactiveCocoa，其中包括UIView元素的一些类别。不确定这是否是问题的根源

以下是由[SLComposeViewController ComposeViewController ForService Type:SLServiceTypeTwitter]引起的崩溃的堆栈跟踪

您需要将MessageUI和StoreKit框架添加到项目中。（在构建阶段->将二进制文件链接到库中）

此错误的典型原因是当您尝试归档未实现NSCoding的对象时。两个内置vc都不会这么做。你做过任何存档吗，或者你使用的第三方lib？我看不出有任何理由在这些VC init方法中进行存档。我怎么知道呢？我不是建议您应该归档，而是建议您的代码在某个地方试图归档一个块（它不应该这样做）。在您的项目中尝试全局搜索“encode”（使用包含匹配）。@danh好吧，但是在内置VC的init方法中怎么会发生这种情况？问题将是由于其他原因造成的。。。它似乎就在那里显现出来了。尝试替换UIViewController aloc init。我打赌你到时候也会看到的。它们已经包含在构建阶段和我的Objective-C文件的头中。我仍然会遇到这个错误。@Peyman你在任何地方用NSDictionary配置UIAppearance吗？我不知道。我的代码中唯一使用UIAppearance的是BButton和SVProgressHUD第三方CoCoCoca控件。
