您可以轻松地使用UIImagePickerController此功能

1. UIImagePickerController *imagePickerController;为该类全局声明
2. 声明协议
   • @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];

使用对象takePicture的方法，UIImagePickerController例如并将其分配给按钮操作，例如：

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

使用委托-imagePickerController:didFinishPickingMediaWithInfo:来获取图像。

-(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。
