使用iPhone SDK访问相机 [英] Access the camera with iPhone SDK

问题描述

很明显，有些人已经能够弄清楚如何通过SDK（Spore Origins）访问iPhone摄像头，但我没有找到任何有用的信息。我不想任何人违反他们的NDA，但有谁知道任何现有的（官方）资源，显示如何这样做？感谢。

It seems obvious that some people have been able to figure out how to access the iPhone camera through the SDK (Spore Origins, for example), but I haven't been able to find any helpful information. I don't want anyone to violate their NDA, but does anyone know of any existing (official) resources that show how this can be done? Thanks.

推荐答案

您需要使用 UIImagePickerController

UIImagePickerController *picker = [[UIImagePickerController alloc] init];
picker.delegate = pickerDelegate
picker.sourceType = UIImagePickerControllerSourceTypeCamera

pickerDelegate 上面的对象需要实现以下方法（ EDIT 现在已弃用，请参见下文）：

The pickerDelegate object above needs to implement the following method (EDIT This is now deprecated, see below):

- (void)imagePickerController:(UIImagePickerController *)picker
                 didFinishPickingImage:(UIImage *)image
                 editingInfo:(NSDictionary *)editingInfo;

在该方法的正文中，图像对象是来自相机的数据，您的具体应用。

Within the body of that method the image object is the data from the camera which you can then use for your specific application.

EDIT

在iPhone OS 3.0 didFinishPickingImage 已被弃用，因此您需要实现：

In iPhone OS 3.0 didFinishPickingImage is deprecated, so instead you'll need to implement:

- (void)imagePickerController:(UIImagePickerController *)picker
                       didFinishPickingMediaWithInfo:(NSDictionary *)info

code>信息将包含原始条目和编辑的图像，用 UIImagePickerControllerOriginalImage 和键UIImagePickerControllerEditedImage 。 （请参见 http://developer.apple。 com / iphone / library / documentation / UIKit / Reference / UIImagePickerControllerDelegate_Protocol / UIImagePickerControllerDelegate / UIImagePickerControllerDelegate.html 了解详情）

The dictionary info will contain entries for the original, and the edited image, keyed with UIImagePickerControllerOriginalImage and UIImagePickerControllerEditedImage respectively. (see http://developer.apple.com/iphone/library/documentation/UIKit/Reference/UIImagePickerControllerDelegate_Protocol/UIImagePickerControllerDelegate/UIImagePickerControllerDelegate.html for more details)
