MFMailComposeViewController可以没有presentModalViewController吗？

Question

苹果提供了使用它使用的MFMailComposeViewController.but的代码

- (IBAction)buttonPressed
{

    MFMailComposeViewController *controller = [[MFMailComposeViewController alloc]init];
controller.mailComposeDelegate = self;

[controller setSubject:@"In app email..."];

[controller setMessageBody:@"...a tutorial from mobileorchard.com" isHTML:NO];

[self presentModalViewController:controller animated:YES];

[controller release];

}默认情况下，它使用自下而上的transition.suppose，如果我想使用下面的内容，它会产生错误的输出。，我可以使用其他的添加子视图来代替presentModalViewController

{

    UIViewAnimationTransition  trans =  UIViewAnimationTransitionFlipFromRight;

[UIView beginAnimations: nil context: nil];
[UIView setAnimationTransition:trans forView: [self view] cache: YES];
    [self presentModalViewController: controller animated:YES];
[UIView commitAnimations];
}

它对其他视图控制器是正确的，但是它在MFMailComposeViewController中没有工作--请给我任何帮助？

嗨，我已经这样做了，但是当前视图控制器翻转，然后composer来自底部.？您能帮忙吗？-(IBAction)clickedMailButton：(Id)发件人

{

  if ([MFMailComposeViewController canSendMail])
{ 

      MFMailComposeViewController *mcontroller = [[MFMailComposeViewController alloc]init];
    //[mcontroller setSubject:@"My Pocket Schedule"];
    [mcontroller setTitle:@"New Message"];
    [mcontroller setMessageBody:@"Check out My Pocket Schedule in the iTune Store" isHTML:NO];
    mcontroller.mailComposeDelegate = self;
    UIViewAnimationTransition  trans =  UIViewAnimationTransitionFlipFromRight;
    [UIView beginAnimations: nil context: nil];
    [UIView setAnimationTransition:trans forView: [self view] cache: YES];
    [self presentModalViewController:mcontroller animated:YES];
    [UIView commitAnimations];
    [mcontroller release];
}

Answer 1

使用modalTransitionStyle属性：

MFMailComposeViewController *mcontroller = [[MFMailComposeViewController alloc] init];
[mcontroller setTitle:@"..."];
[mcontroller setMessageBody:@"..." isHTML:NO];
mcontroller.mailComposeDelegate = self;
mcontroller.modalTransitionStyle = UIModalTransitionStyleFlipHorizontal;
[self presentModalViewController:mcontroller animated:YES];
[mcontroller release];

试一试
