UIView 上的自定义相机，而不是全屏

Question

我正在做一个应用程序，在应用程序的特定部分，用户将能够从相机或 select 从相册中拍摄照片，并且该图像将显示在 ViewController。这有点简单，但是，我需要的是，我无法做到的是： - 我不希望相机全屏打开，我希望它在用户所在的 ViewController 上 'open'，与图像所在的位置完全相同，在一个圆圈内。我可以让相机不全屏打开，但我无法将此视图放入圆形视图中并根据圆形裁剪照片。

这是我的代码，如果您创建一个标准项目，它可能会起作用，我认为这将有助于理解正在发生的事情：

变量

@property (nonatomic, strong) UIImagePickerController * picker;
@property (nonatomic, strong) UIImageView             * photoView;
@property (nonatomic, strong) UIView                  * overlayView;
@property (nonatomic, strong) UIButton * takePhotoButton; //- function
@property (nonatomic, strong) UIButton * selectPhotoButton;
@property (nonatomic, strong) UIButton * takePicture; //- action

Answer 1

使用下面的代码，我得到以下结果：

深蓝色背景的单个视图。
2 个绿色圆圈（按钮）
点击左侧圆圈可将相机 "sight" 放入其中。
点击 "take" 按钮（在左侧圆圈底部）会触发 "takePhotoAction" 方法。

Answer 2

通过将照片裁剪为正方形解决了 PhotoView 上 "smaller image" 的问题，然后设置 PhotoView 的图像。

通过 'setting' picker.view 框架在 x: 0, y:-50, PhotoView.width, PhotoView.height.

完整代码如下：

@interface CameraViewController ()
{
    BOOL isFromAlbum;
}

@end

@implementation CameraViewController

@synthesize photoView;
@synthesize picker;
