电子邮件解决iOS 8

我试图从Xcode 6中打开iOS 8中的电子邮件镇静，但得到一个错误。 如果我从Xcode 5尝试，相同的代码工作正常。后来我从苹果开发者门户网站下载了一个示例代码：

https://developer.apple.com/library/content/samplecode/MessageComposer/Introduction/Intro.html

但结果是一样的。 有没有什么，或者一些设置，我错过了优化Xcode 6的代码

这里是代码：在我的button行动

MFMailComposeViewController *picker = [[MFMailComposeViewController alloc] init]; picker.mailComposeDelegate = self; [picker setSubject:@"Hello from California!"]; // Set up recipients NSArray *toRecipients = [NSArray arrayWithObject:@"[e-mail]"]; NSArray *ccRecipients = [NSArray arrayWithObjects:@"[e-mail]", @"[e-mail]", nil]; NSArray *bccRecipients = [NSArray arrayWithObject:@"[e-mail]"]; [picker setToRecipients:toRecipients]; [picker setCcRecipients:ccRecipients]; [picker setBccRecipients:bccRecipients]; // Attach an image to the email NSString *path = [[NSBundle mainBundle] pathForResource:@"rainy" ofType:@"jpg"]; NSData *myData = [NSData dataWithContentsOfFile:path]; [picker addAttachmentData:myData mimeType:@"image/jpeg" fileName:@"rainy"]; // Fill out the email body text NSString *emailBody = @"It is raining in sunny California!"; [picker setMessageBody:emailBody isHTML:NO]; [self presentViewController:picker animated:YES completion:NULL]; 

电子邮件代表

 self.feedbackMsg.hidden = NO; // Notifies users about errors associated with the interface switch (result) { case MFMailComposeResultCancelled: self.feedbackMsg.text = @"Result: Mail sending canceled"; break; case MFMailComposeResultSaved: self.feedbackMsg.text = @"Result: Mail saved"; break; case MFMailComposeResultSent: self.feedbackMsg.text = @"Result: Mail sent"; break; case MFMailComposeResultFailed: self.feedbackMsg.text = @"Result: Mail sending failed"; break; default: self.feedbackMsg.text = @"Result: Mail not sent"; break; } [self dismissViewControllerAnimated:YES completion:NULL]; 

结果：

电子邮件镇静委托自动消失与结果0，即MFMailComposeResultCancelled

错误代码：MessageComposer [10993：196902] viewServiceDidTerminateWithError：Error Domain = _UIViewServiceInterfaceErrorDomain Code = 3“操作无法完成（_UIViewServiceInterfaceErrorDomain错误3.）”UserInfo = 0x7b93f7e0 {消息=服务连接中断}

从外观上看，这是一个模拟器的问题。 （iOS 8模拟器）globalMailer方法在设备上正常工作。

如果有人遇到这个问题，只需在真实的设备上进行testing。
