iOS在MFMailComposeViewController和SKStoreProductViewController的初始化方法上崩溃

Question

我正在开发具有部署目标7.0的iOS应用，并且试图在应用内展示诸如MFMailComposeViewController和SKStoreProductViewController之类的内置视图控制器。 但是，使用以下错误消息初始化任何内置视图控制器后，我的应用程序就会崩溃：

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

崩溃发生在以下几行：

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

和

SKStoreProductViewController *storeViewController = [[SKStoreProductViewController alloc] init];

我找不到此错误来源的任何线索。 我正在使用一些第三方容器，例如KeepLayout和ReactiveCocoa，它们在UIView元素上包括一些类别。 不知道这是否是此问题的根源。

这是由[SLComposeViewController composeViewControllerForServiceType：SLServiceTypeTwitter]引起的崩溃的堆栈跟踪

您需要将MessageUI和StoreKit框架添加到您的项目中。 （在构建阶段->将二进制文件与库链接）
