UIInterfaceOrientation always return Portrait in A

Question

I want to show the Splash Screen in iPad application. Before that i want to get the current device orientation Landscape or Portrait mode. I have used,

    UIInterfaceOrientation orientation= [[UIApplication sharedApplication] statusBarOrientation];
    if (orientation == UIInterfaceOrientationLandscapeRight || orientation == UIInterfaceOrientationLandscapeLeft)  
    {       
        splachview=[[UIImageView alloc] initWithFrame:CGRectMake(0, 0, 1024, 768)];
        splachview.image=[UIImage imageNamed:@"Default-Landscape.png"];

        splachview.autoresizingMask = UIViewAutoresizingFlexibleLeftMargin | UIViewAutoresizingFlexibleRightMargin;
        splachview.contentMode = UIViewContentModeTop;

        [[UIApplication sharedApplication] setStatusBarHidden:YES withAnimation:NO];
        [self.window addSubview:splachview];
    }
    else if (orientation == UIInterfaceOrientationPortrait || orientation == UIInterfaceOrientationPortraitUpsideDown) 
    {
        splachview=[[UIImageView alloc] initWithFrame:CGRectMake(0, 0, 768, 1024)];
        splachview.image=[UIImage imageNamed:@"Default-Portrait.png"];

        splachview.autoresizingMask = UIViewAutoresizingFlexibleLeftMargin | UIViewAutoresizingFlexibleRightMargin;
        splachview.contentMode = UIViewContentModeTop;

        [[UIApplication sharedApplication] setStatusBarHidden:YES withAnimation:NO];
        [self.window addSubview:splachview];
    }

in Appdelegate.m . The UIInterface orienation always detecting in Portrait mode only. I launched the app in Landscape mode but, the control always detecting Portrait mode only. How can i get the current orientation in AppDelegate.m? Please help me to find the solution. Thanks in advance.

Answer 1

After read your code, seems like what you want is to show a static image when app startup. There is way to do that without any code.

If you want to show any dynamic content as "splash", you may need to process it in a UIViewController.

For get current device orientation, you can read property: [UIDevice currentDevice].orientation. Just for your reference.

You shouldn't do that on the AppDelegate, but rather on a UIViewController. In a UIViewController you can correctly know in what position the device is, by using the appropriate methods (Configuring the View Rotation Settings section) that the class gives you.
