Question

I have an application that on the iPod Touch/iPhone should not rotate. However, I do have an MFMaiComposeViewController for users to send bug reports. How my app is set up though, nothing can rotate, which is fine, except for this single view. How can I make this rotate to landscape. It is declared in one class like this:

//
//  LogbookSecondViewController.h
//  Logbook iDM
//

#import <UIKit/UIKit.h>
#import <MessageUI/MessageUI.h>

@interface LogbookSecondViewController : UIViewController  <MFMailComposeViewControllerDelegate>
{
        MFMailComposeViewController *email;
}

@property (nonatomic, retain) MFMailComposeViewController *email;

@end

In the .m

- (IBAction)sendEmail:(id)sender {
    NSLog(@"ToolsController - Send Email");
    NSString *MailTO = @"[e-mail]";
    email = [[MFMailComposeViewController alloc] init];
    email.mailComposeDelegate = self;
    NSArray *recipitants = [NSArray arrayWithObject:MailTO];
    // Subject
    [email setSubject:@"Bug/Problem/Suggestion, Logbook iDM"];

    [email setToRecipients:recipitants];

    // Present it
    [email setModalPresentationStyle:UIModalPresentationFormSheet];
    [email setModalTransitionStyle:UIModalTransitionStyleCoverVertical];
    [self presentViewController:email animated:YES completion:nil];
}


- (void) mailComposeController:(MFMailComposeViewController *)controller didFinishWithResult:(MFMailComposeResult)result error:(NSError *)error {
    [email dismissViewControllerAnimated:YES completion:nil];

}

How can I allow only this view to rotate? Thanks.

Create your own class MyCustomMailComposeViewController (or whatever) that extends MFMailComposeViewController. All you need to add to the implementation of this class is:

// For iOS 6.0+
- (NSUInteger)supportedInterfaceOrientations {
    return UIInterfaceOrientationMaskLandscape;
}

// For iOS 4.x and 5.x
- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation {
    return UIInterfaceOrientationIsLandscape(interfaceOrientation);
}

This code assumes you want just landscape for the mail composer. Simply return YES if you want all orientations.

Then change:

email = [[MFMailComposeViewController alloc] init];

to:

email = [[MyCustomMailComposeViewController alloc] init];
