Question

我使用 MessageUI框架从我的应用程序发送包含附件的邮件。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

      Reason: image not found

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。

您不必在文件名中键入扩展名。像“iphone.jpg”不起作用。只需在文件名中写“iphone”，因为你已经定义了mimeType。而且你必须定义资源的路径。

下面是附加邮件“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];

此错误似乎与模拟器中运行的邮件有关，而与您的代码无关。甚至库存Apple的样本MailComposer在模拟器中报告相同的错误：

添加以下方法以关闭MFMailComposeViewController：

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

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

 NSLog (@"mail finished");
 }

Answer 4

使用此功能在邮件中附加图像，在ios 4,5,6中进行测试

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