First:

NSString *myEmail = @"3423423423@qq.com";NSString *toemail = @"asdfasdf@gmail.com";NSString *emailDetail = [NSString stringWithFormat:@"mailto:%@?cc=%@&subject=Feedback!&body=Dear:",toemail,myEmail];[[UIApplication sharedApplication] openURL: [NSURL URLWithString: emailDetail]];

Second:

- (void)displayMailPicker {    MFMailComposeViewController *mailPicker = [[MFMailComposeViewController alloc] init];    mailPicker.mailComposeDelegate = self;    [mailPicker setSubject: @"Feedback!"];    NSArray *toRecipients = [NSArray arrayWithObject: @"3434234@qq.com"];    [mailPicker setToRecipients: toRecipients];    NSArray *ccRecipients = [NSArray arrayWithObjects:@"asdfa@gmail.com", nil];    [mailPicker setCcRecipients:ccRecipients];        // add a picture    UIImage *addPic = [UIImage imageNamed: @"icon_logo@2x.png"];    NSData *imageData = UIImagePNGRepresentation(addPic);    [mailPicker addAttachmentData: imageData mimeType: @"" fileName: @"Icon.png"];        NSString *emailBody = @"<font size='4'>Dear:</font>";    [mailPicker setMessageBody:emailBody isHTML:YES];    [self presentViewController:mailPicker animated:YES completion:nil];}- (void)mailComposeController:(MFMailComposeViewController *)controller didFinishWithResult:(MFMailComposeResult)result error:(NSError *)error {    [self dismissViewControllerAnimated:YES completion:nil];}

Generally, the second type is used.

How does ios determine that MFMailComposeViewController is successfully sent?

The mail App does not exist in the simulator. You need to call the email. You must set the email address to debug the device.

How does iOS send emails without calling the system email interface?

Install other email software.
