Question

How can I write my code which supports both landscape and portrait? I tried this one –

(void)setupForOrientation:(UIInterfaceOrientation)orientation {
    if (UIInterfaceOrientationIsPortrait(orientation)) {
        CGRect bounds = CGRectMake(0, 0, 768, 1004);
        scrollView.frame = bounds;
        // Other view positioning for portrait.
    } else {
        CGRect bounds = CGRectMake(0, 0, 1024, 748);
        scrollView.frame = bounds;
        // Other view positioning for landscape.
    }
    [self drawBackgroundForOrientation:orientation];
}

But its not working. Please help me.

Answer 1

Use this code:

- (void)viewDidLoad

    {

    [[UIDevice currentDevice] beginGeneratingDeviceOrientationNotifications];
    [[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(orientationChanged:) name:@"UIDeviceOrientationDidChangeNotification" object:nil];

    }


- (void) orientationChanged:(id)object
{  


 if( [UIApplication sharedApplication].statusBarOrientation == UIInterfaceOrientationLandscapeLeft || [UIApplication sharedApplication].statusBarOrientation == UIInterfaceOrientationLandscapeRight )
 {
 self.view=self.landscapeView;
 NSLog(@"ViewwillAppear= Land");

 }
 else
 {
 self.view = self.portraitView;
 NSLog(@"ViewwillAppear= Port");

 }

You’ll always have to return yes for this function whenever you require orientation support.

- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation

{
return YES;
}

Edit 1: P.S. I’ve taken portraitView & landscapeView as two separate UIViews.
