本文实例为大家分享了ios沙盒视频缩略图及保存本地的具体代码，供大家参考，具体内容如下

获取缩略图

func thumbnailofvideo(path : string)-> uiimage {
  do {
    let asset = avurlasset(url: url(fileurlwithpath: path), options: nil)
    let imggenerator = avassetimagegenerator(asset: asset)
    imggenerator.appliespreferredtracktransform = true
    let cgimage = try imggenerator.copycgimage(at: cmtimemakewithseconds(1, 24), actualtime: nil)
    let uiimage = uiimage(cgimage: cgimage)
    return uiimage
  } catch {
    return uiimage(named: "default_figure")!
  }
}

保存到系统相册

#import <assetslibrary/assetslibrary.h>
- (void)savevideointoalbum {
  nsstring *filedirectory = 
  nsfilemanager *filemanager = [nsfilemanager defaultmanager];
  nsarray *filearray = [filemanager contentsofdirectoryatpath:filedirectory error:nil];
  nsstring *filepath = [filedirectory stringbyappendingpathcomponent:[filearray lastobject]];
  nsurl *fileurl = [nsurl fileurlwithpath:filepath];
  
  nslog(@"fileurl = %@", fileurl);
  alassetslibrary *assetslibrary = [[alassetslibrary alloc] init];
  
  if ([assetslibrary videoatpathiscompatiblewithsavedphotosalbum:fileurl]) {
    [assetslibrary writevideoatpathtosavedphotosalbum:fileurl completionblock:^(nsurl *asseturl, nserror *error) {
      nslog(@"%@-----%@", asseturl, error);
    }];
  } else {
    
  }
}
