从Google Drive下载文件时下载进度状态？ [英] Download Progress Status, when file is downloading from Google Drive?

问题描述

我可以从Google驱动器下载文件，但我想知道下载进度。任何人都可以告诉我如何做到这一点？

我已经试过这个下载文件：

  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（@\\\
\\\
\\\
\\\
\\\
）; 
 NSLog（@This is File Size =====>％@，file.fileSize）; 
 NSLog（@这是文件名称===>％@，file.title）; 
 $ b $ if（file.downloadUrl！= nil）
 {
 if（data！= nil）
 {
 filename = file.title; 
 
 NSArray * paths = NSSearchPathForDirectoriesInDomains（NSDocumentDirectory，NSUserDomainMask，YES）; 
 NSString * documentsDirectory = [paths objectAtIndex：0]; 
 documentsDirectory = [[paths paths objectAtIndex：0] stringByAppendingPathComponent：[NSString stringWithFormat：@％@，filename]]; 
 [data writeToFile：documentsDirectory atomically：YES]; 
  

解决方案

我找到了一个更简单的解决方案。有一个块将用于进度的回调：

$ $ $ $ $ $ $ $ $ c $ gt; 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]）） ;
}];

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];

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]));
}];
