如何防止模态UIImagePickerController旋转？ [英] How to prevent a modal UIImagePickerController from rotating?

问题描述

我有一个完全支持旋转的应用。我在模态上添加了一个 UIImagePickerController ，其中不支持 UIInterfaceOrientationLandscape ，我无法让控制器留在肖像中。

I have an app that fully support rotation. I am modally adding a UIImagePickerController for which there is no support for UIInterfaceOrientationLandscape and I cannot get the controller to stay in portrait.

换句话说，我需要禁用 UIImagePickerController 的旋转，以便它保持纵向，而无需移除旋转对于我的应用程序的其余部分。这似乎是基本的，但我似乎找不到它。如何防止轮换？

In other words, I need to disable rotation for the UIImagePickerController so it stays in portrait, without removing rotation for the rest of my app. this seems basic, but I can't seem to locate it. How can I prevent this rotation?

更新

根据建议，我尝试使用以下代码进行子类化：

As suggested, I tried subclassing with the following code:

@interface UAImagePickerController : UIImagePickerController {
}
@end

@implementation UAImagePickerController
- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)toInterfaceOrientation {
    return UIDeviceOrientationIsPortrait(toInterfaceOrientation);
}
@end

这条线完全没有被击中断点...我认为必须有一些关于 UIImagePickerView

The line is not being hit at all with a breakpoint… i think there must be something funky about the UIImagePickerView

推荐答案

的时髦子类 UIImagePickerController 并让新类实现 shouldAutorotateToInterfaceOrientation：使其仅旋转为肖像，如下所示：

Subclass UIImagePickerController and have that new class implement shouldAutorotateToInterfaceOrientation: to make it rotate to portrait only, something like this:

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