I am able to download files from Google drive, but I want to know the download progress. Can any one tell me how to do it?

I have tried this for downloading the files:

NSString *downloadURL = [[self.driveFiles objectAtIndex:indexPath.row] downloadUrl];
GTMHTTPFetcher *fetcher = [self.driveService.fetcherService fetcherWithURLString:downloadURL];
filename=[[NSString alloc] init];
[fetcher beginFetchWithCompletionHandler:^(NSData *data, NSError *error)
 {
     GTLDriveFile *file = [driveFiles objectAtIndex:indexPath.row];
     NSLog(@"\n\n\n\n\n");
     NSLog(@"This is File Size=====>%@",file.fileSize);
     NSLog(@"This is file Name===>%@",file.title);

     if(file.downloadUrl!= nil)
     {
         if (data!=nil)
         {
             filename=file.title;

             NSArray *paths =    NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
             NSString *documentsDirectory = [paths objectAtIndex:0];
             documentsDirectory = [[paths   objectAtIndex:0]stringByAppendingPathComponent:[NSString stringWithFormat:@"%@",filename]];
             [data writeToFile:documentsDirectory atomically:YES];

  • It's very hard to answer a question like this without providing anymore information. You could provide the code you use, and maybe a link to the API etc. – IluTov Aug 26 '13 at 12:12

  • Does the `myFetcher:receivedData:` method get called at all? – IluTov Aug 26 '13 at 13:25
  • You have to add your instance as a delegate, so call `[fetcher beginFetchWithDelegate:self didFinishSelector:@selector(completionMethod)];`, now copy the code you had in the completion block into a method called `completionMethod`. The `myFetcher:receivedData:` method should now get called automatically – IluTov Aug 26 '13 at 13:27
  • You have my support email, what's the problem? Delete your comments, they don't belong here – IluTov Oct 03 '13 at 12:47

Edit

I found a much simpler solution. There is a block that will be used for callbacks of the progress:

GTMHTTPFetcher *fetcher =
    [self.driveService.fetcherService fetcherWithURLString:downloadURL];
GTLDriveFile *file = [driveFiles objectAtIndex:indexPath.row];

[fetcher setReceivedDataBlock:^(NSData *data) {
    NSLog(@"%f%% Downloaded", (100.0 / [file.fileSize longLongValue] * [data length]));
}];
