Ios UIImagePickerController和接口方向

我的应用程序是通用的。iPad仅为横向（左侧或右侧）；iPhone只是一个肖像

按照编码，iPhone的一切都很正常，但我在iPad上尝试演示UIImagePickerController时遇到了以下错误

错误 这是我的设置

Info.plist（iPad支持的方向） 视图控制器显示选择器 }

UIImagePickerController类别 值得注意

---

UIImagePickerController（在iPad中）是从UIPopoverController（在

UIImagePickerController

类别使用中）呈现的视图控制器呈现的

-(NSUInteger)supportedInterfaceOrientations {  
    if(isPad()){
        return UIInterfaceOrientationMaskLandscape;
    }
    else{
        return UIInterfaceOrientationMaskPortrait;
    }
}

事实证明，您必须在iPad上的popover中显示UIImagePickerController。

UIImagePickerController类仅支持纵向模式。请参见

不应使用类别覆盖方法。仅当图像选择器不适用于相机时，才应如此。对于相机，图像选择器应显示在全屏模式视图控制器中。感谢您的澄清！
