olg / objc-s3 Goto Github PK

I've just downloaded S3 Browser - really nice bit of software. One suggestion I have though - for mass downloads (I just downloaded 396 files this way), instead of downloading them 1 by 1 and asking the filename, ask once which folder to save to, and save the file using the key of the object in the S3 bucket.

I'm using objc-s3 because this is the only code for OSX/Objective C that handle Amazon S3.
The code works fine for uploading, but not downloading.
Using

• (BOOL) downloadFromBucket:(NSString_)theBucket key:(NSString_)key saveTo:(NSString*)path
  {

  S3Bucket *bucket = [[S3Bucket alloc] initWithName: theBucket];
  S3Object *objectToDownload = [[S3Object alloc] initWithBucket:bucket
  key:key
  userDefinedMetadata:nil
  metadata:nil
  dataSourceInfo:nil];

  S3DownloadObjectOperation* op = [[S3DownloadObjectOperation alloc]
  initWithConnectionInfo:[self connectionInfo]
  object: objectToDownload
  saveTo:path
  ];

  [_queue addToCurrentOperations:op];
  [op release];
  return TRUE;

}

This is generating an error. It seems that the code is not generating the correct signature. Can you fix the problem ?

PS: I've obfucated some bits

I think we should investigate whether changes are required to accommodate Amazon's plan to change how S3 paths work for newly created buckets.
