Question

我是objective-c的新手，并且一直在寻找这个问题的答案......

我正在创建一个照片共享应用程序，我希望相机是全屏的。我使用以下代码隐藏默认的相机覆盖并创建我自己的相机，并使相机全屏。在下一个屏幕上，我想再次显示捕获为全屏的图像，但图像正在侧面折叠。

设置相机覆盖：

-(void)loadCamera {
self.imagePicker = [[UIImagePickerController alloc]init];
self.imagePicker.sourceType = UIImagePickerControllerSourceTypeCamera;
self.imagePicker.delegate = self;
self.imagePicker.cameraCaptureMode = UIImagePickerControllerCameraCaptureModePhoto;
self.imagePicker.showsCameraControls = NO;

self.overlayIV = [[WAUCameraOverlayView alloc]initWithFrame:self.imagePicker.cameraOverlayView.frame];

[self.imagePicker.cameraOverlayView addSubview:self.overlayIV];

CGAffineTransform translate = CGAffineTransformMakeTranslation(0.0, 71.0); //This slots the preview exactly in the middle of the screen by moving it down 71 points
self.imagePicker.cameraViewTransform = translate;

CGAffineTransform scale = CGAffineTransformScale(translate, 1.333333, 1.333333);
self.imagePicker.cameraViewTransform = scale;

[self presentViewController:self.imagePicker animated:YES completion:nil];

}

以上代码效果很好，并使用我的自定义叠加层使相机全屏显示。然后，执行此代码块：

- (void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info {
[self.overlayIV removeFromSuperview];
UIImage *image = [info objectForKey:UIImagePickerControllerOriginalImage];

}

我将“图像”传递到下一个屏幕并将其初始化为屏幕大小，但它会被拉伸...任何方式来保存/显示从全屏相机捕获的图像的确切比例和大小？

编辑：我用来显示图片的代码是：

UIImageView *capturedImageView =[[UIImageView alloc]initWithFrame:self.frame];
capturedImageView.image = aImage;
    capturedImageView.contentMode = UIViewContentModeScaleAspectFill;
    [self addSubview:capturedImageView];

我希望图像的大小与屏幕相同，并且与相机中拍摄的比率/宽高度相同
