Question

我做了一个示例ipad邮件编写器应用程序将图像发送到另一个地址。所以我写了以下代码：

#import  <messageUI/MFMailComposeViewController.h>
//to compose mail
-(IBAction)composeMail{ 
    if([self validateImageView]){
        [self sendSelectedImage];
    }
    else{
        [self showAlert];
    }


}

//to validate image view
-(BOOL)validateImageView{
    if(selectedImageView.image){
        return YES;
    }
    else{
        return NO;
    }
}

//to send selected image
-(void)sendSelectedImage{   

    MFMailComposeViewController *picker = [[MFMailComposeViewController alloc] init];
    @try {
        picker.mailComposeDelegate = self;  
        [picker setSubject:@"Hello from Triassic!"];


        // Set up recipients
        NSArray *toRecipients = [NSArray arrayWithObject:@"shamsudheen@triassicsolutions.com"]; 
        NSArray *ccRecipients = [NSArray arrayWithObjects:@"shamsudheen@triassicsolutions.com", @"shamsudheen@triassicsolutions.com", nil]; 
        NSArray *bccRecipients = [NSArray arrayWithObject:@"shamsudheen@triassicsolutions.com"]; 

        [picker setToRecipients:toRecipients];
        [picker setCcRecipients:ccRecipients];  
        [picker setBccRecipients:bccRecipients];

        // Attach an image to the email 
        NSData *myData =  UIImagePNGRepresentation(selectedImageView.image);
        [picker addAttachmentData:myData mimeType:@"image/jpeg" fileName:@"rainy"]; 
        // Fill out the email body text
        NSString *emailBody = @"It is raining in Trivandrum!";
        [picker setMessageBody:emailBody isHTML:NO];

        [self presentModalViewController:picker animated:YES];
    }
    @catch (NSException * ex) {
        NSLog([NSString stringWithFormat:@"%@",ex]);
    }
    @finally {
        [picker release];
    }

}

//to show a alert box
-(void)showAlert{   
    UIAlertView *alertView;     
    alertView = [[UIAlertView alloc] initWithTitle:@"Please select a image from PhotoAlbums!" message:nil delegate:self cancelButtonTitle:nil otherButtonTitles:@"Continue", nil];
    [alertView show];
    [alertView release];        
}

// Override to allow orientations other than the default portrait orientation.
- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation {
    return (interfaceOrientation==UIInterfaceOrientationLandscapeRight || interfaceOrientation==UIInterfaceOrientationLandscapeLeft);
}

#pragma mark -
#pragma mark Dismiss Mail/SMS view controller

// Dismisses the email composition interface when users tap Cancel or Send. Proceeds to update the 
// message field with the result of the operation.
- (void)mailComposeController:(MFMailComposeViewController*)controller 
          didFinishWithResult:(MFMailComposeResult)result error:(NSError*)error {
    @try {
        feedbackMsg.hidden = NO;
        // Notifies users about errors associated with the interface
        switch (result)
        {
            case MFMailComposeResultCancelled:
                feedbackMsg.text = @"Mail sending canceled";
                break;
            case MFMailComposeResultSaved:
                feedbackMsg.text = @"Mail saved";
                break;
            case MFMailComposeResultSent:
                feedbackMsg.text = @"Mail sent";
                break;
            case MFMailComposeResultFailed:
                feedbackMsg.text = @"Mail sending failed";
                break;
            default:
                feedbackMsg.text = @"Mail not sent";
                break;
        }

    }
    @catch (NSException * ex) {
        NSLog([NSString stringWithFormat:@"%@",ex]);
    }
    @finally {
        [self dismissModalViewControllerAnimated:YES];
    }

}

因此，当撰写按钮单击时，它将显示一个弹出窗口，其中包含输入的邮件地址和所有详细信息。它显示结果发送过程成功完成。但我没有收到任何邮件到shamsudheen@triassicsolutions.com。可能我知道我做了什么错误。我通过进入弹出窗口通过这个发送邮件到另一封电子邮件地址section.i认为compose方法在弹出加载时有效。然后我如何发送邮件到在显示的弹出窗口输入的地址。工作不正常..可能我知道我做错了什么

在模拟器中，您无法发送邮件，因为如果您想首先向其他人发送邮件，则必须在设备的帐户设置中设置邮件详细信息（您必须登录到您的帐户）。但是模拟器中不存在该功能。这就是您无法从模拟器发送电子邮件的原因。
