我正在尝试接收我选择发送电子邮件的电子邮件。但我不知道如何设置我在 MFMailComposeViewController 视图中选择的用户的接收者。
if ([MFMailComposeViewController canSendMail])
{
mailer = [[MFMailComposeViewController alloc] init];
mailer.mailComposeDelegate = self;
[mailer setSubject:@"A Message from blablabl"];
NSMutableArray *usersTo = [[NSMutableArray alloc] init];
toRecipients = usersTo;
[mailer setToRecipients:toRecipients];
NSString *emailBody = @"blablablabal";
[mailer setMessageBody:emailBody isHTML:YES];
// only for iPad
// mailer.modalPresentationStyle = UIModalPresentationPageSheet;
[self presentModalViewController:mailer animated:YES];

A couple things are wrong here.
这里有几件事是错误的。
1 )
1)
MFMailComposeViewController's setToRecipientsmethod expects an immutable array with recipients already set.
MFMailComposeViewController 的setToRecipients方法需要一个已设置收件人的不可变数组。
2 )
2)
And you're setting it to a blank mutable array.
你将它设置为一个空白的可变数组。
Try something like this:
尝试这样的事情：
NSArray *usersTo = [NSArray arrayWithObject: @"[email protected]"];
[mailer setToRecipients:usersTo];
And you should see it work.
你应该看到它起作用了。

MFMailComposeViewController *picker = [[MFMailComposeViewController alloc] init];
NSArray *toRecipients = [NSArray arrayWithObjects:@"[email protected]",@"[email protected]",nil];
[picker setToRecipients:toRecipients];

MFMailComposer In “ Swift “ and “ Objective c “
*********************************************
In objective c
Steps:
1. Create new project.
2. Add a button into storyboard.
3. In .h add header file like “Import <MessageUI/MessageUI.h>”
4. Add delegate to ViewController “ MFMailComposeViewControllerDelegate”
5. In Button Action {
NSString *emailTitle = “”
NSString *messageBody = “”
NSArray *toRecipents = “”
MFMailComposeViewController *VC = [[MFMailComposeViewController]alloc init];
VC.mailComposeDelegate = self;
[VC.setSubject: emailTitle];
[VC.setMessageBody: messageBody];
[VC.setToRecepents: toRecipents];
if([MFMailComposeViewController canSendMail]) {
[self presentViewController:mc animated:YES completion:NULL];
}
6.MailComposeController Function
- (void) mailComposeController:(MFMailComposeViewController *)controller didFinishWithResult:(MFMailComposeResult)result error:(NSError *)error
{
switch (result)
{
case MFMailComposeResultCancelled:
NSLog(@"Mail cancelled");
break;
case MFMailComposeResultSaved:
NSLog(@"Mail saved");
break;
case MFMailComposeResultSent:
NSLog(@"Mail sent");
break;
case MFMailComposeResultFailed:
NSLog(@"Mail sent failure: %@", [error localizedDescription]);
break;
default:
break;
}
[self dismissViewControllerAnimated:YES completion:NULL];
}
7. And also add FrameWork: MessageUI.FrameWork
8. Run the App into mobile or Simulator.
In Swift:
*******
Steps:
1. Create New Project
2. Add a button Storyboard
3. In ViewController.Swift Class File Import MessageUI
4. In Button Action ConfiguredMailComposer below Steps
{
let mailComposeViewController = configuredMailComposeViewController()
if MFMailComposeViewController.canSendMail()
{
self.present(mailComposeViewController, animated: true, completion: nil)
self.showSendmailSuccesfulAlert()
} else {
self.showSendMailErrorAlert()
}
5. Implement the configure mail composer
func configuredMailComposeViewController() -> MFMailComposeViewController {
let mailComposerVC = MFMailComposeViewController()
mailComposerVC.mailComposeDelegate = self
mailComposerVC.setToRecipients(["[email protected]"])
mailComposerVC.setSubject("Sending you an in-app e-mail...")
mailComposerVC.setMessageBody("Sending e-mail in-app is not so bad!", isHTML: false)
return mailComposerVC
}
6. MailComposer optional method
func mailComposeController(_ controller: MFMailComposeViewController, didFinishWith result: MFMailComposeResult, error: Error?) {
controller.dismiss(animated: true, completion: nil)
}
7. After completed the step no: run the app into device or simulator.
