我似乎无法取代过时的sizeWithFont与boundingRecWithSize正确.我仔细检查了所有的答案,并熬夜试图解决这个问题.我真的需要一些比我聪明的人的帮助.这是我试图修改的代码.任何帮助,将不胜感激.

CGSize sizeForText = [faqItem.answer sizeWithFont:[UIFont boldSystemFontOfSize:14]
   constrainedToSize:CGSizeMake(self.tblView.bounds.size.width - padding, MAXFLOAT)
   lineBreakMode:NSLineBreakByWordWrapping];

[sectionInfo insertObject:[NSNumber numberWithFloat:roundf(sizeForText.height + 5)]
  inRowHeightsAtIndex:0];

在iOS 6中,MFMailComposeViewController如果用户尝试发送第二封电子邮件,则不会解散...

第一次出现并发送电子邮件,一切都很完美.但是,如果再次选择电子邮件选项,则MFMailComposeViewController取消时不会解除.

这是我实现它的方式:

- (IBAction)buttonEmailClick:(id)sender {
    if (![MFMailComposeViewController canSendMail]) {
        UIAlertView *alert = [[UIAlertView alloc] initWithTitle:@"Can't send" message:@"This device is unable to send emails." delegate:nil cancelButtonTitle:@"OK" otherButtonTitles:nil];
        [alert show];
        return;
    }
    NSDictionary *contactsInfo = [self contactsInfoFromPlistNamed:kConfigPlistName];
    [mailComposeViewController setToRecipients:[NSArray arrayWithObject:[contactsInfo objectForKey:@"email"]]];
    //[mailComposeViewController setSubject:kEmailDefaultSubject];
    //[mailComposeViewController setMessageBody:text isHTML:NO];
    [self presentModalViewController:mailComposeViewController animated:YES];
}

然后这个:

- (void)mailComposeController:(MFMailComposeViewController*)controller didFinishWithResult:(MFMailComposeResult)result error:(NSError*)error {
    UIAlertView *alert = nil;
    if (result == MFMailComposeResultSent) {
        alert = [[UIAlertView alloc] initWithTitle:@"Sent" message:@"Your email was sent." delegate:nil cancelButtonTitle:@"OK" …
