hi,
I want to take large video input from the gallery and take in my app, I have a code that is deprecated, I have a video URL, anyone helps me to save this video's URL to another path.

I get the video URL by using a photo kit but I don't know how can I make a copy of this video and keep it in another path (my app).

before I use this code

  [[NSFileManager defaultManager] createFileAtPath:path contents:nil attributes:nil];
  NSOutputStream *outPutStream = [NSOutputStream outputStreamToFileAtPath:path append:YES];
  [outPutStream open];

  long long offset = 0;
  long long bytesRead = 0;

  NSError *error;
  uint8_t * buffer = malloc(131072);
  double ok = [assetRep size] ; //ok  double  24011099
//  id size = [assetRep size] ;
  while (
      offset < ok && [outPutStream hasSpaceAvailable]) {

    bytesRead =
    [assetRep
     getBytes:buffer
     fromOffset:offset
     length:131072
     error:&error
     ];

    [outPutStream write:buffer maxLength:bytesRead];
    offset = offset+bytesRead;
  }
  [outPutStream close];
  free(buffer);

thanks

I found one solution which is works for me.

path = where you want to append your stream.

NSString *path = [directroyPath stringByAppendingFormat:@"%@",videoName];

// [videoData writeToFile:path atomically:YES];

  [[NSFileManager defaultManager] createFileAtPath:path contents:nil attributes:nil];

NSInputStream *stream = [NSInputStream inputStreamWithURL:URL];


NSInteger result;

uint8t * buffer = malloc(131072);// BUFFERLEN can be any positive integer
NSOutputStream *outputStream = [NSOutputStream outputStreamToFileAtPath:path append:YES];
[stream open];
[outputStream open];



while((result = [stream read:buffer maxLength:131072]) != 0) {
  if(result > 0) {
   // buffer contains result bytes of data to be handled
   //[data appendBytes:buffer length:result];
   [outputStream write:buffer maxLength:result];
  } else {
   // The stream had an error. You can get an NSError object using [iStream streamError]
   if (result<0) {
    [NSException raise:@"STREAM_ERROR" format:@"%@", [stream streamError]];
   }
  }
}
[outputStream close];
[stream close];
free(buffer);
