Set ZBar iOS SDK interface orientation?

Question

Does anyone know how to set the interface orientation for the ZBar SDK? I need it to work in landscape view and not portrait. I tried adding [reader shouldAutorotateToInterfaceOrientation:UIInterfaceOrientationLandscapeRight];but it didn't work. Any ideas?

Answer 1

Create a wrapper class around ZBarReaderView and add the iOS 6 methods:

-(BOOL) shouldAutorotate
{
    return NO;
}

-(NSUInteger) supportedInterfaceOrientations
{
    return UIInterfaceOrientationMaskLandscape;
}

Then use the class you created over the built in ZBar one, make sure you keep the old iOS 5 methods in the same controller:

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

and also:

    self.reader.supportedOrientationsMask = ZBarOrientationMask(UIInterfaceOrientationMaskLandscape);

I know it's late, but I just got around to doing this myself for iOS 6.

Answer 2

I got the same issue and resolved it symply !

I just needed to call :

[reader willRotateToInterfaceOrientation: toInterfaceOrientation duration: duration];

within the willRotate... of the view controller that contains the ZbarReaderView.

I'm not sure exactly what you mean but maybe this help you ...

[[UIApplication sharedApplication] setStatusBarOrientation: UIInterfaceOrientationLandscapeLeft animated:NO];

or

[[UIDevice currentDevice] setOrientation:UIInterfaceOrientationLandscapeLeft];
