Objective c - UIActivityViewController orientation mode

Question

My iPhone app is design to support portrait orientation only, except one view controller that present photos, and support landscape mode as well.

So overall my project

Answer 1

i had similar problems in the app i am currently developing. i ended up overwriting more of the rotation methods to make sure my own viewcontroller stays in portrait.

that's what worked for me (IOS5+):

- (BOOL) shouldAutorotate {
    return YES;
}

- (NSUInteger)supportedInterfaceOrientations {
    return UIInterfaceOrientationMaskPortrait;
}

- (UIInterfaceOrientation)preferredInterfaceOrientationForPresentation {
    return UIInterfaceOrientationPortrait;
}

- (BOOL)shouldAutorotateToInterfaceOrientation (UIInterfaceOrientation)interfaceOrientation {
    return (interfaceOrientation == UIInterfaceOrientationPortrait);
}

if you are pre ios5 or that's not working for you have a look at: http://developer.apple.com/library/ios/#documentation/uikit/reference/UIViewController_Class/Reference/Reference.html

hope you get it to work. :)

May be u should try

- (void)viewWillAppear:(BOOL)animated
{
   [self shouldAutorotateToInterfaceOrientation: UIInterfaceOrientationLandscapeRight];
   [super viewWillAppear:animated];
}

on your view?

You should make another uinavigationcontroller and present uiactivityviewcontroller from there. In this code _image is a UIImage yo wan to share. BlankViewController is just place holder viewcontroller you can create in IB you can also make it's view's background colour to clear and do what ever appearance changes you want to do.

__weak  CurrentViewController  *weakSelf    =   self  ;

UIActivityViewController *activityViewController = [[UIActivityViewController alloc] initWithActivityItems:@[_image] applicationActivities:nil]   ;
UIViewController        *viewC  =   [[UIViewController alloc] initWithNibName:@"BlankViewController" bundle:nil] ;
UINavigationController  *navC   =   [[UINavigationController alloc] initWithRootViewController:viewC]  ;
activityViewController.completionHandler = ^(NSString *activityType, BOOL completed)
{
    [weakSelf dismissViewControllerAnimated:NO completion: ^ {
        ;    // Your completion handler
    }]  ;
};
[self presentViewController:navC animated:NO completion: ^ {
    [navC presentViewController:activityViewController animated:YES completion: ^ {
        ;
    }]  ;
}];

Couldn't found a solution to this problem, so I ended up implementing my own email UIActivity subclass...
