首先导入头文件

#import 

使用当前的URL过滤到我们想要的数据

 	PHFetchResult *result = [PHAsset fetchAssetsWithALAssetURLs:@[assetUrl] options:nil];

    PHAsset * asset = result.firstObject;


    /// 包含该视频的基础信息
    PHAssetResource * resource = [[PHAssetResource assetResourcesForAsset: PHAsset] firstObject];

    NSLog(@"%@",resource);
    /*
     type:
     originalFilename:
     */

    

PHAsset - 获取视频数据

 	PHVideoRequestOptions *options = [[PHVideoRequestOptions alloc] init];
    options.version = PHImageRequestOptionsVersionCurrent;
    options.deliveryMode = PHVideoRequestOptionsDeliveryModeAutomatic;
    
    PHImageManager *manager = [PHImageManager defaultManager];
    [manager requestAVAssetForVideo:asset
                            options:options
                      resultHandler:^(AVAsset * _Nullable asset, AVAudioMix * _Nullable audioMix, NSDictionary * _Nullable info) {
                          // asset 类型为 AVURLAsset  为此资源的fileURL
                          // 
                          AVURLAsset *urlAsset = (AVURLAsset *)asset;
                          // 视频数据
                          NSData *vedioData = [NSData dataWithContentsOfURL:urlAsset.URL];
                          NSLog(@"%@",vedioData);
                      }];
