Force landscape for one view controller ios

Question

I\'ve looked at several answers to questions similar but none of the answer worked. I have an app where I need everything portait except for one photo viewer I have. In th

Answer 1

Yes this is possible, you can use this code:

    -(NSUInteger)application:(UIApplication *)application supportedInterfaceOrientationsForWindow:(UIWindow *)window {
        return UIInterfaceOrientationMaskLandscape;
    }

    -(BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)orientation {
        return orientation==UIInterfaceOrientationMaskLandscape;
    }

OR

Try this method in your app delegate

- (NSUInteger)application:(UIApplication *)application supportedInterfaceOrientationsForWindow:(UIWindow *)window {
    if (sglobalorientation isEqualToString:@"AllOrientation"]) {
        return UIInterfaceOrientationMaskLandscape;
    } else {
        return UIInterfaceOrientationMaskAll;
    }
}

you need to change the variable value sglobalorientation to that string value AllOrientation before you move to that Landscape view controller

and in your Landscape view controller, use this code in your view will appear

 [[UIApplication sharedApplication] setStatusBarOrientation:UIInterfaceOrientationLandscapeLeft];
    DigitalSignatureViewController *digisign = [[DigitalSignatureViewController alloc]init];
    [self presentModalViewController:digisign animated:NO];
    [self dismissModalViewControllerAnimated:NO];
- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation
{
    return NO;
}

and again when you move to next view controller change the sglobalorientation string value and follow the same step in your next view controller.

Answer 2

Since the answer seems to be hidden in the comments of the question and since ArunMak's answer is quite confusing, I'll just offer what I found out:

All I had to do was to add this function to my custom UIViewController subclass for the view:

- (NSUInteger)supportedInterfaceOrientations {
    if ([[UIDevice currentDevice] userInterfaceIdiom] == UIUserInterfaceIdiomPad) {
        // iPad: Allow all orientations
        return UIInterfaceOrientationMaskAll;
    } else {
        // iPhone: Allow only landscape
        return UIInterfaceOrientationMaskLandscape;
    }
}

Note that the project needs to allow all orientations (that is: Portrait, Landscape Left, Landscape Right - but NEVER Upside Down on an iPhone!).

If you want to limit some or most views to Portrait, you need to implement the above method in every of those view controllers (or use a common super class for it and subclass all others from it) — if you limit the Device Orientation in the Info.plist to just Portrait, the app will never even think of going into landscape.

Lets try this code:

    [UIApplication sharedApplication].statusBarOrientation = UIInterfaceOrientationLandscapeRight;
self.navigationController.view.center = CGPointMake(([UIScreen mainScreen].bounds.size.width/2), [UIScreen mainScreen].bounds.size.height/2);
CGFloat angle = 90 * M_PI / 180;
self.navigationController.view.transform = CGAffineTransformMakeRotation(angle);
self.navigationController.view.bounds = CGRectMake(0, 0,[UIScreen mainScreen].bounds.size.height , [UIScreen mainScreen].bounds.size.width);
