通过拆分视图控制器启动的模态视图问题 [英] Problems with modal view launched over a split view controller

问题描述

我创建了一个以模式视图启动页面开头的拆分视图应用程序.问题在于，即使ipad处于横向，模态视图也始终以纵向模式启动.如果我旋转ipad几次，它会适当旋转.我已经在Info.plist中设置了UIInterfaceOrientation，但是没有任何影响.

I have created a split view application that begins with a modal view splash page. The problem is that the modal view always launches in portrait mode, even if the ipad is in landscape. If I rotate the ipad a couple of times, it rotates appropriately. I have set UIInterfaceOrientation in my Info.plist, but it doesn't have any impace.

在 didFinishLaunchingWithOptions 中，我正在使用以下代码

in didFinishLaunchingWithOptions, I am using the following code

...
[self.window addSubview:splitViewController.view];
SplashViewController *modalView = [[SplashViewController alloc] intiWithNibName:nil bundle:nil];
modalView.modalPresentationStyle = UIModalPresentationFullScreen;
[splitViewController presentModalViewController:modalView animated:YES];
...

关于如何确保模式视图在横向启动的任何建议?

Any suggestions on how I can ensure the modal view launches in landscape?

推荐答案

我认为这是更好的方法:

I think this is the better way to do it:

- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation
{
    // Return YES for supported orientations
    if (interfaceOrientation == UIInterfaceOrientationLandscapeLeft || interfaceOrientation==UIInterfaceOrientationLandscapeRight) {
        return YES;
    }
    return NO;
}
