谁能帮我解决这个问题？这适用于iPhone 4、iPhone 3gs和iPad1。

尝试运行示例代码，看看这是否是您的代码或设备的问题。如果问题出在你的代码上，试着从didFinishLaunchingWithOptions中以增量方式注释出内容

还要注意像MFMailComposeViewController这样的类，在使用它们之前，您必须检查它的功能，如canSendMail

我曾经在调试中途断开设备时遇到过这种情况。在重新启动设备之前，我收到了这个错误消息。你已经试过了吗？是的，我已经试过了。但仍然是味精和空白屏幕出现。。！对这个错误感到沮丧。我的代码在iphone和ipad上运行，它只在ipod上显示空白屏幕！！我已经检查了这两份文件我什么也没找到。。
