Iphone iOS中的分割视频

我必须将视频分成两部分。我正在使用此微调功能twicely是一种很好的方法。我已经阅读了

AVFoundation

框架，但没有找到任何直接的解决方案来拆分视频。但是有一些iPhone应用程序正在非常顺利地拆分视频。它们是否使用微调功能？需要建议吗

-(void)splitSecondVideo{
    NSString *deleteVideo = [_videoPath path];

    AVURLAsset *asset = [AVURLAsset URLAssetWithURL:_videoPath options:nil];

    AVAssetExportSession *exportSession = [[AVAssetExportSession alloc]initWithAsset:asset presetName:AVAssetExportPresetLowQuality];
     NSString *outputURL = nil;
     NSString *videoFileName = nil;
     videoFileName = [SPUtility getDefaultVideoName];
     outputURL = [NSString stringWithFormat:@"%@/%@.mov", _clipFolderPath, videoFileName];

    NSFileManager *manager = [NSFileManager defaultManager];
    [manager createDirectoryAtPath:outputURL withIntermediateDirectories:YES attributes:nil error:nil];
    [manager removeItemAtPath:outputURL error:nil] ;
     exportSession.outputURL = [NSURL fileURLWithPath:outputURL];
     exportSession.shouldOptimizeForNetworkUse = YES;
     exportSession.outputFileType = AVFileTypeQuickTimeMovie;
     // Trim to half duration
     double halfDuration = CMTimeGetSeconds([asset duration])/2.0;
     double fullDuration = CMTimeGetSeconds([asset duration]);

     CMTime firsthalfDuration = CMTimeMakeWithSeconds(halfDuration, 1);
     CMTime secondhalfDuration = CMTimeMakeWithSeconds(fullDuration, 1);

     CMTimeRange secondrange = CMTimeRangeMake(firsthalfDuration, secondhalfDuration);

     exportSession.timeRange = secondrange;

     [exportSession exportAsynchronouslyWithCompletionHandler:^(void)
     {
     switch (exportSession.status) {
     case AVAssetExportSessionStatusCompleted:
     [manager removeItemAtPath:deleteVideo error:nil];
     NSLog(@"Export Complete %d %@", exportSession.status, exportSession.error);
     break;
     case AVAssetExportSessionStatusFailed:
     NSLog(@"Failed:%@",exportSession.error);
     break;
     case AVAssetExportSessionStatusCancelled:
     NSLog(@"Canceled:%@",exportSession.error);
     break;
     default:
     break;
     }

     }];


}

你有什么发现吗？如果是，发布资源链接@用户1111您必须修剪视频，然后保存它。没有其他选项可以直接分割视频。
