【问题描述】：

我使用 MessageUI 框架 从我的应用程序发送带有附件的邮件。但是我得到了以下错误，

2009-09-07 19:52:23.483 emailTest[11711:5b17]
 Error loading /Developer/Platforms/iPhoneSimulator.platform/Developer/SDKs/iPhoneSimulator3.0.sdk/System/Library/DataClassMigrators/AccountMigrator.migrator/AccountMigrator:  dlopen(/Developer/Platforms/iPhoneSimulator.platform/Developer/SDKs/iPhoneSimulator3.0.sdk/System/Library/DataClassMigrators/AccountMigrator.migrator/AccountMigrator, 265): Library not loaded: /System/Library/PrivateFrameworks/MobileWirelessSync.framework/MobileWirelessSync

[Switching to process 11711 local thread 0xf03]

我的代码是，

MFMailComposeViewController *picker = [[MFMailComposeViewController alloc]init];
picker.mailComposeDelegate = self;
[picker setSubject:@"This is iPhone email   attachment test"];

UIImage *sampleImg = [UIImage imageNamed:@"iPhone.jpg"];
NSData *imageData = UIImageJPEGRepresentation(sampleImg, 1);
[picker addAttachmentData:imageData mimeType:@"image/png" fileName:@"iPhone.jpg"];


NSString *emailBody = @"I am sending the image attachment with iPhone email service";
[picker setMessageBody:emailBody isHTML:YES];

[self presentModalViewController:picker animated:YES];
[picker release];

请帮帮我。

【问题讨论】：

更具体 - 您正在运行什么代码来创建附件？要分离消息？您究竟是如何“使用 MessageUI 框架”的？
请看代码。
嗨，你的代码工作了吗？触摸电子邮件中的发送按钮时，我也收到了相同的消息。但是，我没有在邮件中添加任何附件。当我触摸取消按钮时，我无法关闭邮件控制器。我正在将邮件控制器添加到 cocos2d 层。请提供任何帮助。谢谢。

【解决方案1】：

您不必在文件名中输入扩展名。像“iphone.jpg”不起作用。只需在文件名中写入“iphone”，因为您已经定义了 mimeType。而且您还必须定义资源的路径。

以下是在邮件中附加“rainy.png”文件的示例代码。

MFMailComposeViewController *picker = [[MFMailComposeViewController alloc] init];
picker.mailComposeDelegate = self;

[picker setSubject:@"Hello"];


// Set up recipients
NSArray *toRecipients = [NSArray arrayWithObject:@"first@example.com"]; 
NSArray *ccRecipients = [NSArray arrayWithObjects:@"second@example.com", @"third@example.com", nil]; 
NSArray *bccRecipients = [NSArray arrayWithObject:@"fourth@example.com"]; 

[picker setToRecipients:toRecipients];
[picker setCcRecipients:ccRecipients];  
[picker setBccRecipients:bccRecipients];

// Attach an image to the email
NSString *path = [[NSBundle mainBundle] pathForResource:@"rainy" ofType:@"png"];
NSData *myData = [NSData dataWithContentsOfFile:path];
[picker addAttachmentData:myData mimeType:@"image/png" fileName:@"rainy"];

// Fill out the email body text
NSString *emailBody = @"It is raining";
[picker setMessageBody:emailBody isHTML:NO];

[self presentModalViewController:picker animated:YES];
[picker release];

【解决方案2】：

此错误似乎与模拟器中正在运行的邮件有关，而不是与您的代码有关。甚至库存 Apple 的示例 MailComposer 在模拟器中也报告了相同的错误：

嗨，我在日志中得到了同样的结果。当我触摸邮件控制器中的关闭或发送按钮时。我正在将邮件控制器添加到 cocos2d 层。而且我没有得到“在模拟器中运行邮件而不是在您的代码中运行邮件”。它是什么？我们可以改变它吗？谢谢。

【解决方案3】：

添加以下方法来关闭 MFMailComposeViewController：

- (void)mailComposeController:(MFMailComposeViewController*)controller didFinishWithResult:   (MFailComposeResult)result error:(NSError*)error

 {
 // NEVER REACHES THIS PLACE
 [self dismissModalViewControllerAnimated:YES];

 NSLog (@"mail finished");
 }

【讨论】：

好点，但这可能不是这里的问题......顺便说一句，应该是MFMailComposeResult而不是MFailComposeResult。

【解决方案4】：

将此用于在邮件中附加图像，在 ios 4、5、6 中测试

    MFMailComposeViewController *mailer = [[MFMailComposeViewController alloc] init];
    UIImage *myImage = [UIImage imageNamed:@"image.png"];
    NSData *imageData = UIImagePNGRepresentation(myImage);
    [mailer addAttachmentData:imageData mimeType:@"image/png" fileName:@"image"];
