iphone - 无法设置MFMessageComposeViewController的收件人？

Question

我有这样的方法:

void sendSMS{

        if ([MFMessageComposeViewController canSendText]) {

            MFMessageComposeViewController *picker = [[MFMessageComposeViewController alloc] init];

            picker.recipients = [NSArray arrayWithObject:@"0933660805"];
            [picker  setBody:@"Message body"];
            picker.messageComposeDelegate = self;

            [self.navigationController  presentModalViewController:picker animated:YES];
            //[picker release];

            return;

        }

    }

邮件编辑器打开，但是收件人和邮件正文为空(下图)。任何人都知道我该如何解决它:(

选择这个，然后检查可能会解决您的问题

void sendSMS
{
    if ([MFMessageComposeViewController canSendText]) {
        MFMessageComposeViewController *picker = [[MFMessageComposeViewController alloc] init];
        picker.messageComposeDelegate = self;
        NSString *bodyString = nil;

        NSMutableArray *toRecipients = [[NSMutableArray alloc]init];
        [toRecipients addObject:@"0933660805"];
        [picker setRecipients:(NSArray *)toRecipients];
        [toRecipients release];

        bodyString = [NSString stringWithFormat: @"Message body"];
        [picker setBody:bodyString];

        [self presentModalViewController:picker animated:YES];
        [picker release];
}
