在Unity中集成iOS设备的拍照和录像功能需要借助Unity的插件或者平台支持。iOS提供了一个名为AVFoundation的框架,这个框架包含了处理音频和视频流的所有必要工具。
1. **拍照**:
- 使用Unity的`AVCapturePhotoLibrary` API,可以请求用户访问相册并捕获照片。首先,创建一个`AVCaptureSession`实例,然后配置`AVCaptureStillImageRequest`用于抓取照片,并从设备相机获取图像数据。
```csharp
using UnityEngine;
using UnityEngine.UI;
using UnityEngine.Experimental.XR;
public class CapturePhoto : MonoBehaviour
{
public Button captureButton;
private void Start()
{
// 初始化相机
var photoLibrary = new AVCapturePhotoLibrary();
captureButton.onClick.AddListener(TakePhoto);
}
void TakePhoto()
{
// 请求访问权限...
photoLibrary.RequestAuthorization(UIImagePickerController.SourceType.PhotoLibrary, (status) =>
{
if (status == UIImagePickerController AuthorizationStatus.Authorized)
{
var settings = new AVCapturePhotoSettings();
// 创建照相请求...
var request = new AVCapturePhotoRequest(settings);
// 开始拍照
var session = new AVCaptureSession();
session.AddInput(new AVCaptureDeviceInput(device: null)); // 替换为实际的摄像头输入
session.BeginConfiguration();
session.AddRequest(request);
session.CommitConfiguration();
// 获取照片完成后再处理
session.PhotoCaptureDelegate = new PhotoCaptureDelegate();
}
});
}
}
```
2. **录制视频**:
- 使用`AVCaptureMovieWriter`来记录视频。设置好视频尺寸、帧率、编码等参数,开始录制,并监听` AVCaptureFileOutputRecordingDelegate` 来控制录制和停止。
```csharp
using UnityEngine;
using UnityEngine.Video;
public class RecordVideo : MonoBehaviour
{
public Button recordButton;
public string outputFilePath;
private AVCaptureSession _session;
private AVCaptureMovieFileOutput _movieFileOutput;
void Start()
{
_session = new AVCaptureSession();
// ...其他配置...
recordButton.onClick.AddListener(Record);
}
void Record()
{
// ...添加输入和输出...
_movieFileOutput.StartRecordingToOutputFile(outputFilePath, recordingDelegate);
}
private void StopRecord()
{
_movieFileOutput.FinishRecording();
}
private class recordingDelegate : AVCaptureFileOutputRecordingDelegate
{
public override void didFinishRecordingToOutputFile(AVMediaType mediaType, AVMutableComposition composition, AVCaptureConnection connection, NSError error)
{
if (error != null)
{
Debug.LogError(error.LocalizedDescription);
}
else
{
StopRecord();
}
}
}
}
```
