启动屏幕不会改变iPad的方向？

我在iPad应用程序中工作。我有4个启动屏幕的图像（横向右侧，左侧和纵向，纵向向上向下）。当我以纵向模式启动应用程序时，启动屏幕显示良好，但如果我将方向更改为Landscaper，启动屏幕不会更改其方向。你能给我提些建议吗？今天我需要提交应用程序。请帮帮我。提前谢谢。这是我的密码

 -(void) showSplash
{
    UIInterfaceOrientation orientation= [[UIApplication sharedApplication] statusBarOrientation];
    if (orientation == UIInterfaceOrientationLandscapeLeft ||
        orientation == UIInterfaceOrientationLandscapeRight)  //  UIDeviceOrientationLandscapeLeft
    {       
        NSLog(@"Splash Landscape");
        UIViewController *splash=[[UIViewController alloc] init];
        splachview=[[UIImageView alloc] initWithFrame:CGRectMake(0, 0, 1024, 768)];
        splachview.image=[UIImage imageNamed:@"Default-Landscape.png"];
        [splash.view addSubview:splachview];

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

        [[UIApplication sharedApplication] setStatusBarHidden:YES withAnimation:NO];
        [self presentModalViewController:splash animated:NO];
        [self performSelector:@selector(hideSplash) withObject:nil afterDelay:10.0];
        [splash release];
        [splachview release];
    }
    else if (orientation == UIInterfaceOrientationPortrait ||
             orientation == UIInterfaceOrientationPortraitUpsideDown) //  UIDeviceOrientationPortrait
    {
        NSLog(@"Splash Portrait");
        UIViewController *splash=[[UIViewController alloc] init];
        splachview=[[UIImageView alloc] initWithFrame:CGRectMake(0, 0, 768, 1024)];
        splachview.image=[UIImage imageNamed:@"Default-Portrait.png"];
        [splash.view addSubview:splachview];

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

        [[UIApplication sharedApplication] setStatusBarHidden:YES withAnimation:NO];
        [self presentModalViewController:splash animated:NO];
        [self performSelector:@selector(hideSplash) withObject:nil afterDelay:10.0];
        [splash release];
        [splachview release];
    }   
}

请纠正我的错误。启动屏幕不会改变其方向。谢谢。

将您的启动文件命名为

iPad的

Default-Landscape.png

和

Default-Landscape.png

Default.png'和

Default@2x.png`对于iPhone

---

请记住文件名区分大小写，所以请仔细检查它们

谢谢Saurabh先生。我已经将它们命名为启动屏幕Default-LandscapeLeft.png、Default-LandscapeLeft.png、Default-rapital.png、Default-rapitalupsidedown.png。这是否正确，或者我是否需要更改您提到的上述名称。请帮帮我。今天我需要提交应用程序。谢谢。再澄清一次。我有两张左右的风景图片。我需要换个名字。请帮帮我，谢谢。我更改了名称，但当我旋转（更改方向）ipad时，启动屏幕不支持方向。你能帮帮我吗。我将发布我的代码。请纠正我的错误。谢谢
