Question

我有一个iPhone应用程序，可以从App内置的相册中选择照片。现在我想添加一个共享按钮，其中包含通过电子邮件分享此照片的选项，我可以通过此代码附加现有照片：

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

[picker setSubject:@""];


// Set up recipients
NSArray *toRecipients = [NSArray arrayWithObject:@""]; 
[picker setToRecipients:toRecipients];


// Attach an image to the email
NSString *path = [[NSBundle mainBundle] pathForResource:@"project existing photo" ofType:@"jpg"];
NSData *myData = [NSData dataWithContentsOfFile:path];
[picker addAttachmentData:myData mimeType:@"image/jpeg" fileName:@"photo name"];

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

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

但是，我需要在此代码中更改以将选定的相册附加到电子邮件正文中？提前谢谢。

使用UIImagePickerController允许用户选择图片。然后它将调用此委托方法。

- (void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info {
    UIImage* image = [info objectForKey:UIImagePickerControllerOriginalImage];
    NSData* data = UIImageJPEGRepresentation(image, 1.0);
    // Your e-mail code here
}

嗨使用UIImagePicker从相机的PhotoLibrary中选择图像并使用MFMailComposeViewController发送电子邮件。

-(void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info {

// Dismiss PickerViewController 

[picker dismissModalViewControllerAnimated:NO]; 

// Get Image Fro Attachment

UIImage* image = [info objectForKey:UIImagePickerControllerOriginalImage];
NSData* data = UIImageJPEGRepresentation(image, 1.0);

// Setup Email Settings Like Subject, Message , Attachment


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

[mailPicker setSubject:@"Image Attachment Test"];


// Set recipients

NSArray *toRecipients = [NSArray arrayWithObject:@"xyz.gmail.com"]; 
[mailPicker setToRecipients:toRecipients];

// Set body message here
NSString *emailBody = @":)";
[picker setMessageBody:emailBody isHTML:NO];

// Attach Image as Data 
[mailPicker addAttachmentData:myData mimeType:@"image/jpeg" fileName:@"photo name"];

[self presentModalViewController:mailPicker animated:YES];

[mailPicker release];


}

假设您有一个来自图像选择器（或任何其他来源）的 UIImage ，您首先需要从图像中创建 NSData 对象。使用 UIImageJPEGRepresentation 或 UIImageJPEGRepresentation 功能。获得 NSData 对象后，将其添加为附件，就像您在发布的代码中所做的那样。

在大多数情况下，图像将显示在主邮件正文之后的电子邮件中。
