如何判断UIImagePickerController cameraOverlayview是否旋转? [英] How do you tell whether UIImagePickerController cameraOverlayview will rotate or not?

问题描述

Ipad上的IOS 6在横向模式下旋转UIImagePickerController cameraOverlayView，但iphone 3GS上的IOS 6不能旋转-谢谢Apple！

IOS 6 on the Ipad rotates the UIImagePickerController cameraOverlayView on landscape mode, but IOS 6 on the iphone 3GS does not - thank you Apple!

我不知道IOS 5或其他设备的行为，因此有一种预测这种行为的方法，以便可以在叠加视图上应用旋转变换吗?

I dont know the behaviour for IOS 5, or other devices, so is there a way of predicting this behaviour so i can apply a rotation transform on the overlay view?

谢谢

推荐答案

我也遇到了这个问题.这是我发现的:

I had this issue as well. Here's what I discovered:

在目标的"iPad部署信息"配置中，确保已启用左向左"和向右向右"模式-即使您的应用程序并不真正支持这些模式(也可以通过info.plist来完成)文件也很明显).

In the Target's "iPad Deployment Info" config, make sure you've enabled "Landscape Left" and "Landscape Right" modes - even if your app doesn't really support these (this can be done through the info.plist file as well, obviously).

接下来，在您的UIViewController中，将其强制设为人像:

Next, in your UIViewController(s), force them to Portrait:

- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation
{
    return UIInterfaceOrientationIsPortrait(interfaceOrientation);
}

- (BOOL)shouldAutorotate
{
    return YES;
}

- (NSUInteger)supportedInterfaceOrientations
{
    return UIInterfaceOrientationMaskPortrait | UIInterfaceOrientationMaskPortraitUpsideDown;
}

现在，将iPad旋转到横向时，UIImagePickerController应该可以正确旋转-但是您的UIViewController仍将是纵向模式.

Now the UIImagePickerController should rotate correctly when the iPad is rotated to landscape - but your UIViewController will still be Portrait-only.
