我怎样才能通过iPhone中的邮件附加iphone图像

我是iphone开发新手。我在视图中创建了一个按钮。点击按钮时，它会从iPhone中加载光子库。现在我想通过邮件附加这些选定的图像。我不知道如何在MFMailComposerView中附加图像。我怎样才能通过iPhone中的邮件附加iphone图像

我怎样才能做到这一点，

这里我的代码，

-(IBAction) Pictures:(id)sender 
{ 
    self.imgpicker = [[UIImagePickerController alloc] init]; 
    self.imgpicker.delegate = self; 
    self.imgpicker.sourceType = UIImagePickerControllerSourceTypePhotoLibrary; 
    [self presentModalViewController:self.imgpicker animated:YES]; 
} 

- (void)imagePickerController:(UIImagePickerController *)picker didFinishPickingImage:(UIImage *)img1 editingInfo:(NSDictionary *)editInfo { 
    [[picker parentViewController] dismissModalViewControllerAnimated:NO]; 
    UIView *view = [[UIView alloc] init]; (This view for displaying the images) 
    imageview = [[UIImageView alloc] initWithImage:img1]; 
    [imageview setFrame:CGRectMake(0, 0, 320, 420)]; 
    [self.view addSubview:imageview]; 
    [view release]; 

    UIBarButtonItem *rightbutton = [[UIBarButtonItem alloc] initWithTitle:@"Email" style:UIBarButtonItemStyleBordered target:self action:@selector(rightbutton)]; 
    self.navigationItem.rightBarButtonItem = rightbutton; 
    [rightbutton release]; 

    } 

    -(void) rightbutton 
    { 
     [self emailImage:(UIImage *)image];(how to pass the image to mail view) 
    } 

    - (void)emailImage:(UIImage *)image 
    { 
     picker = [[MFMailComposeViewController alloc] init]; 
     picker.mailComposeDelegate = self; 
     [picker setToRecipients:[NSArray arrayWithObjects:@"[email protected]",nil]]; 
     NSData *data = UIImagePNGRepresentation(image); 
     [picker addAttachmentData:data mimeType:@"image/png" fileName:@"iPod Library Image"]; 
     [self presentModalViewController:picker animated:YES]; 
     [picker release]; 
    }

请帮助我。

谢谢。

一眼就看不出代码有什么问题（我的应用程序使用UIImagePNGRepresenation的方式与您的相同）。究竟发生了什么问题？ – 2010-04-03 10:42:57

如何将图像从didFinishPickingImage方法发送到右键方法。以便我可以将图像传递给邮件。 – Pugal 2010-04-03 11:03:58

您应该在控制器类（imageThatWasPicked等）中设置UIImage实例变量，然后在从-imagePickerController:didFinishPickingImage:editingInfo:获取图像时设置该实例变量。您可以在致电-emailImage:时参考此实例变量。

请注意，您正在泄漏imageView，我不知道您在图像选择器代理方法中如何处理view。你完全可以摆脱代码分配和释放view。
