我的应用中唯一允许的方向是横向.我在target> summery下的项目属性中强制执行此操作,并且仅允许纵向显示shouldAutorotateToInterfaceOrientation

问题是当我在水平握住手机(横向)的同时拍照时,照片将以横向拍摄,而UI仍处于纵向模式.

这意味着在横向模式下,我得到了3264 x 2448的宽图像,而不是我在纵向模式下的高图像(2448 x 3264).

接下来,用户可以裁剪图像,但如果以横向模式拍摄图像,我会得到非常难看的拉伸图像.添加边框或将UI切换为横向不是一种选择.

UIImagePickerController即使手机水平放置(横向模式),有没有办法强制以纵向尺寸拍摄照片？

我UIImagePickerController使用以下设置初始化:

    imagePicker =[[UIImagePickerController alloc] init];
    imagePicker.sourceType = UIImagePickerControllerSourceTypeCamera;
    imagePicker.cameraCaptureMode = UIImagePickerControllerCameraCaptureModePhoto;
    imagePicker.cameraDevice = UIImagePickerControllerCameraDeviceRear;
    imagePicker.showsCameraControls = NO;
    imagePicker.modalPresentationStyle = UIModalPresentationFullScreen;
    imagePicker.wantsFullScreenLayout = YES;
    imagePicker.cameraViewTransform = CGAffineTransformScale(imagePicker.cameraViewTransform,CAMERA_TRANSFORM, CAMERA_TRANSFORM);
    imagePicker.navigationBarHidden = YES;
    imagePicker.toolbarHidden = YES;
    [self presentModalViewController:imagePicker animated:NO];
    imagePicker.cameraOverlayView = self.cameraOverlay;
    imagePicker.cameraFlashMode = UIImagePickerControllerCameraFlashModeOff;
