我怎樣才能通過iPhone中的郵件附加iphone圖像

我是iphone開發新手。我在視圖中創建了一個按鈕。點擊按鈕時，它會從iPhone中加載光子庫。現在我想通過郵件附加這些選定的圖像。我不知道如何在MFMailComposerView中附加圖像。我怎樣才能通過iPhone中的郵件附加iphone圖像

我怎樣才能做到這一點，

這裏我的代碼，

-(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]; 
    }

請幫助我。

謝謝。

一眼就看不出代碼有什麼問題（我的應用程序使用UIImagePNGRepresenation的方式與您的相同）。究竟發生了什麼問題？ – 2010-04-03 10:42:57

如何將圖像從didFinishPickingImage方法發送到右鍵方法。以便我可以將圖像傳遞給郵件。 – Pugal 2010-04-03 11:03:58

您應該在控制器類（imageThatWasPicked等）中設置UIImage實例變量，然後在從-imagePickerController:didFinishPickingImage:editingInfo:獲取圖像時設置該實例變量。您可以在致電-emailImage:時參考此實例變量。

請注意，您正在泄漏imageView，我不知道您在圖像選擇器代理方法中如何處理view。你完全可以擺脫代碼分配和釋放view。
