Iphone – MFMailComposer – works in simulator but not in iPhone 2G

iphone

I am trying to add MFMailComposer to my iPhone app and not having much luck getting it to launch in my iPhone 2G. It always launches the email app to the accounts page and closes my app. Works like a charm in the simulator.

-(void)viewWillAppear:(BOOL)animated
{
[super viewWillAppear:animated];

[self displayComposerSheet];

}
-(void)displayComposerSheet
{

Class mailClass = (NSClassFromString(@"MFMailComposeViewController"));
if (mailClass != nil)
{
    // you have the MFMailComposeViewController class
    MFMailComposeViewController *picker =  [[MFMailComposeViewController alloc] init];
picker.mailComposeDelegate = self;

NSArray *mailArr = [[NSArray alloc] initWithObjects:self.sendTo,nil];       

[picker setSubject:@"Hello from iCamp America"];
[picker setToRecipients:mailArr];
NSString *emailBody = @"\n\n\email created with iCamp America\nwww.iCampAmerica.com";
[picker setMessageBody:emailBody isHTML:NO];

[self presentModalViewController:picker animated:YES];
[picker release];
[mailArr release];
}
else
{
    UIAlertView *alert = [[UIAlertView alloc] initWithTitle:nil message:@"You cannot send an email !" delegate:self cancelButtonTitle:@"OK" otherButtonTitles:nil]; 
    [alert show]; 
    [alert release]; 
}

}

Best Answer

The MFMailComposeViewController is only available on iPhone OS > 3.0. Are you running that version your development phone?

    }

    -(void)callMailComposer{

        Class mailClass = (NSClassFromString(@"MFMailComposeViewController"));
        if (mailClass != nil)
        {
        // We must always check whether the current device is configured for sending emails
            if ([mailClass canSendMail])
                [self displayComposerSheet];
            else
                [self launchMailAppOnDevice];
        }

        }
    }

        NSString *tosubject =@"";
        [picker setSubject:tosubject];

        [self presentModalViewController:picker animated:YES];

        if(picker) [picker release];
        if(picker) picker=nil;

    }


    // Dismisses the email composition interface when users tap Cancel or Send. Proceeds to update the message field with the result of the operation.

        - (void)mailComposeController:(MFMailComposeViewController*)controller didFinishWithResult:(MFMailComposeResult)result error:(NSError*)error
{    
  NSString* alertMessage;
  // message.hidden = NO;
  // Notifies users about errors associated with the interface
  switch (result)

      break;
    default:
      alertMessage = @"Email Not Sent";

      break;
  }

  UIAlertView* alertView = [[UIAlertView alloc] initWithTitle:@"My app name" 
                                                      message:alertMessage
                                                     delegate:nil
                                            cancelButtonTitle:@"OK"

        NSString *email = [NSString stringWithFormat:@"%@%@", recipients, body];
        email = [email stringByAddingPercentEscapesUsingEncoding:NSUTF8StringEncoding];
        [[UIApplication sharedApplication] openURL:[NSURL URLWithString:email]];

    }

Objective-c – UIAlertView not displaying complete message

There is a way.

When you present your alert, you can just implement this method:

- (void)willPresentAlertView:(UIAlertView *)alertView {
alertView.frame = CGRectMake(alertView.frame.origin.x, alertView.frame.origin.y -50
                             ,alertView.frame.size.width, 300);
}

Adjust the height to fit your need. It will look something like this:

alt text

If you need to move the button around, you can just add new lines (\n) to your message, and it will move the button down.
