您可以轻松使用 UIImagePickerController为此

1. 声明UIImagePickerController *imagePickerController;全局范围内的类
2. 声明协议(protocol)
   • @interface YourClassName : UIViewController <UINavigationControllerDelegate, UIImagePickerControllerDelegate>

imagePickerController = [[UIImagePickerController alloc] init];
[imagePickerController setDelegate:self];
[imagePickerController setSourceType:UIImagePickerControllerSourceTypeCamera];
[imagePickerController setMediaTypes:@"public.image"]]; //specify image (not video)
[imagePickerController setShowsCameraControls:NO]; //hide default camera controls
[imagePickerController setNavigationBarHidden:YES];
[imagePickerController setToolbarHidden:YES];
[imagePickerController setAllowsEditing:NO];
[self.view addSubview:imagePickerController.view];

使用 takePicture UIImagePickerController 的方法像这样的对象并将其分配给按钮操作，例如:

-(IBAction)btnTakePictureAct:(UIButton *)sender
{
    [imagePickerController takePicture];
}

使用委托(delegate) -imagePickerController:didFinishPickingMediaWithInfo:获取图像。

-(void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info
{
    UIImage *image = info[UIImagePickerControllerOriginalImage];
}

看到这个，得到一个想法，制作你的自定义相机控件。
