Iphone 如何强制UIImagePickerController以横向模式录制视频

我的应用程序正在运行potrate模式，但我想在横向模式下录制视频

    self.imgPicker = [[UIImagePickerController alloc] init];
        self.imgPicker.editing=FALSE;
        //self.imgPicker.allowsImageEditing = YES;
        self.imgPicker.delegate = (id)self;

        [self.imgPicker shouldAutorotateToInterfaceOrientation: UIInterfaceOrientationLandscapeRight];
        //self.imgPicker.sourceType = UIImagePickerControllerSourceTypePhotoLibrary;
    #if !(TARGET_IPHONE_SIMULATOR)    
        self.imgPicker.sourceType = UIImagePickerControllerSourceTypeCamera;
    #endif
imgPicker.sourceType=UIImagePickerControllerSourceTypePhotoLibrary;
            NSArray *mediaTypesAllowed = [NSArray arrayWithObject:@"public.movie"];
            [imgPicker setMediaTypes:mediaTypesAllowed];
            [self.imgPicker shouldAutorotateToInterfaceOrientation: UIInterfaceOrientationLandscapeRight];
            [self presentModalViewController:imgPicker animated:YES];

我想在默认情况下以横向模式加载UIImagePickerController

请指导我如何操作。

正如Apple doc所述，UIImagePickerController从现在起将被称为UIIPC，仅在纵向模式下工作。您的应用程序将被重新发布。无论如何，你可以尝试这个在横向模式下打开

    self.imgPicker = [[UIImagePickerController alloc] init];
        self.imgPicker.editing=FALSE;
        //self.imgPicker.allowsImageEditing = YES;
        self.imgPicker.delegate = (id)self;

        [self.imgPicker shouldAutorotateToInterfaceOrientation: UIInterfaceOrientationLandscapeRight];
        //self.imgPicker.sourceType = UIImagePickerControllerSourceTypePhotoLibrary;
    #if !(TARGET_IPHONE_SIMULATOR)    
        self.imgPicker.sourceType = UIImagePickerControllerSourceTypeCamera;
    #endif
imgPicker.sourceType=UIImagePickerControllerSourceTypePhotoLibrary;
            NSArray *mediaTypesAllowed = [NSArray arrayWithObject:@"public.movie"];
            [imgPicker setMediaTypes:mediaTypesAllowed];
            [self.imgPicker shouldAutorotateToInterfaceOrientation: UIInterfaceOrientationLandscapeRight];
            [self presentModalViewController:imgPicker animated:YES];
