MFMailComposeViewController在iPad上崩溃

Question

我在iPhone和iPad上使用以下代码iPad兼容。

if([MFMailComposeViewController canSendMail])
{
     dispatch_async(dispatch_get_main_queue(), ^{

         MFMailComposeViewController *mailcomposer=[[MFMailComposeViewController alloc] init];
         [mailcomposer setMailComposeDelegate:self];
         [mailcomposer setToRecipients:[NSArray arrayWithObject:recipients]];
         [self presentViewController:mailcomposer animated:YES completion:nil];
      });
}

它在iPhone上运行良好，但在iPad的情况下，模态已打开，几秒钟后它就会自动被解雇。将其置于调试模式后，我在下面找到了日志。

viewServiceDidTerminateWithError: Error Domain=_UIViewServiceInterfaceErrorDomain Code=3 "The operation couldn’t be completed. (_UIViewServiceInterfaceErrorDomain error 3.)" UserInfo=0x7fbb904040f0 {Message=Service Connection Interrupted}

您可以在真实的物理设备/ iPad上运行MFMailComposeViewController，但它可能会在模拟器上出现问题。
