MFMailComposeViewController 未在 ios 5 中填充收件人

Question

我正在尝试将邮件发送到我从数据库中接收的电子邮件数组列表，当我发送时，收件人列表填充在iOS 7中，但当我尝试iOS 5收件人列表时没有填充。知道为什么吗？这是我的邮件功能

-(void)sendEmailToContacts:(NSArray *)fList withText:(NSString *)emailText withTag:(NSInteger )tag
{
    if([MFMailComposeViewController canSendMail])
    {
        MFMailComposeViewController *mailComposer = [[MFMailComposeViewController alloc] init];
        mailComposer.view.tag=tag;
        NSString *htmlBody =[NSString stringWithFormat:@"<a href="%@">%@</a>",_currentAdd.contentUrl,addtext];
        [mailComposer setMessageBody:htmlBody isHTML:YES];
        [mailComposer setSubject:_currentMail.subject];
        mailComposer.mailComposeDelegate = self;
        [mailComposer setToRecipients:fList];
        [self presentViewController:mailComposer animated:YES completion:nil];
    }
    else
    {
       NSLog(@"Device is unable to send email in its current state.");
    }
}

我的fList（收件人列表）是一个NSArray，这是我的fList的示例输出

(
    "[e-mail]",
    "[e-mail]",
    "[e-mail]",
    "[e-mail]"
)

Answer 1

收件人应为不可变数组。 检查阵列类型

  NSArray *usersTo = [NSArray arrayWithObject: @"[e-mail]"];
    [mailComposer setToRecipients:usersTo];

Answer 2

试试这个。

        NSArray *fList = [NSArray arrayWithObjects:@"[e-mail]",@"[e-mail]",@"[e-mail]",@"[e-mail]",@"[e-mail]", nil];
        MFMailComposeViewController *mailComposer = [[MFMailComposeViewController alloc] init];
        mailComposer.view.tag=tag;
        NSString *htmlBody =[NSString stringWithFormat:@"<a href="%@">%@</a>",_currentAdd.contentUrl,addtext];
        [mailComposer setMessageBody:htmlBody isHTML:YES];
        mailComposer.mailComposeDelegate = self;
        [mailComposer setSubject:_currentMail.subject];
        mailComposer.delegate = self;
        [mailComposer setToRecipients:fList];
        [self presentViewController:mailComposer animated:YES completion:nil];

Answer 3

-(void)sendEmailToContacts:(NSArray *)fList withText:(NSString *)emailText withTag:(NSInteger )tag
{
    if([MFMailComposeViewController canSendMail])
    {
        MFMailComposeViewController *mailComposer = [[MFMailComposeViewController alloc] init];
        //mailComposer.view.tag=tag;
        NSString *htmlBody =[NSString stringWithFormat:@"<a href="%@">%@</a>",_currentAdd.contentUrl,addtext];
        [mailComposer setMessageBody:htmlBody isHTML:YES];
        [mailComposer setSubject:_currentMail.subject];
        mailComposer.mailComposeDelegate = self;
        [mailComposer setToRecipients:fList];
        [self presentViewController:mailComposer animated:YES completion:nil];
    }
    else
    {
       NSLog(@"Device is unable to send email in its current state.");
    }
}

显然，如果我尝试在设置收件人行之前设置标签，则问题在于设置标签，它将在iOS 5中不显示收件人列表，如果设置标签行被注释掉或在setToRecipients之后设置，它将起作用。
