iphone电子邮件附件(iphone email attachment)

我用MessageUI框架与我的应用程序附件发送邮件。但我得到了以下错误，

我的代码，

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];

请帮我。

Answer 1:

你不必在你的文件名类型扩展名。像“iphone.jpg”是行不通的。只是写在文件名“iphone”，因为你已经定义mime类型。而且还必须定义资源路径。

下面是示例代码添加“rainy.png”文件，邮件。

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];

Answer 2:

这个错误似乎与正在运行的邮件诠释他的模拟器，而不是你的代码。即使库存苹果的样品MailComposer报告在模拟器上相同的错误：

Answer 3:

添加下面的方法来关闭该MFMailComposeViewController：

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

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

 NSLog (@"mail finished");
 }

Answer 4:

用这个在邮件附加的图像，在IOS 4,5,6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"];
