MFMailComposeViewController in landscape - mfmailcomposeviewcontroller

Question

My application is in landscape mod.When i call MFMailComposeViewController through Present model view, it comes in landscape mod.I rotate device and MFMailComposeViewController view goes to portrait mod i want to restrict this rotation it should always be in landscape mod only.Is there any way to do it..

Answer 1

Subclass the MFMailComposeViewController class, so that you can override its shouldAutorotateToInterfaceOrientation to display it however you like:
#interface MailCompose : MFMailComposeViewController {
}
#end
#implementation MailCompose
// Override to allow orientations other than the default portrait orientation.
- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation {
// Return YES for supported orientations
return (interfaceOrientation == UIInterfaceOrientationLandscapeLeft);
}
#end
Specify the new class in place of MFMailComposeViewController:
MailCompose *controller = [[MailCompose alloc] init];
controller.mailComposeDelegate = self;
[controller setSubject:#"In app email..."];
[controller setMessageBody:#"...email body." isHTML:NO];
[self presentModalViewController:controller animated:YES];
[controller release];

I found that a simple category for MFMailComposeViewController also worked. Since I like my app to rotate to any angle, I created & linked in MFMailComposeViewController+Rotate.h:
#import <Foundation/Foundation.h>
#import <MessageUI/MFMailComposeViewController.h>
#interface MFMailComposeViewController (Rotate)
#end
and MFMailComposeViewController+Rotate.m
#import "MFMailComposeViewController+Rotate.h"
#implementation MFMailComposeViewController (Rotate)
- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation
{
// Return YES for supported orientations
return YES;
}
- (NSUInteger)supportedInterfaceOrientations {
// return the desired orientation mask from http://developer.apple.com/library/ios/#documentation/UIKit/Reference/UIApplication_Class/Reference/Reference.html
return /*mask*/;
}
#end
For my base line testing purposes (iOS 3.1.3), I don't seem to need to put it into the root view controller.
It is worth noting that BEFORE I did this, after my app would load MFMailComposeViewController, it would then stop rotating to any other orientation, even after MFMailComposeViewController was dismissed! Now my app remains freely rotatable.

This worked for me, perfectly, with one minor change:
MailCompose *controller = [[MailCompose alloc]
initWithRootViewController:self.navigationController];
...
And I was convinced that I had to call the base-class initWithRootViewController method. Otherwise, how would the MFMailComposeViewController know about it? But it turns out the example above that simply calls [[MailCompose alloc] init] is enough. The underlying MFMailComposeViewController "just knows" how to display itself.
I love happy surprises like this. I posted this in case it is equally illuminating for anyone else.

Create a new controller and inherit it from MFMailComposeViewController.In this controller just write one function shouldautorotate thing. Create instance of this.Now it will be working fine.
