永远不会在Google API for ios中上传数据进度 [英] Never getting uploading data progress in google API for ios

问题描述

我在我的应用程序中使用GoogleDrive API从我的应用程序上传文件。到目前为止，我成功地找到了上传所有类型文件的良好结果。

I am using GoogleDrive API in my application to upload files from my application. So far I succeeded and finding good results for uploading all types of files.

我跟着 Google示例上传文件。

我试图在上传时显示进度，具体取决于文件大小。我在google给出的示例代码中经历了很多课程，但结果并不多。

I am trying to show the progress, dependent on file size, while uploading. I have gone through many classes in the google given example code but there isn't much result.

获取文件上传进度的步骤：

我在GTLServices.m中找到了以下方法

I have found below method In GTLServices.m

- (void)setUploadProgressBlock:(GTLServiceUploadProgressBlock)block {
  [uploadProgressBlock_ autorelease];
  uploadProgressBlock_ = [block copy];

  if (uploadProgressBlock_) {
    // As above, we need the fetcher to call us back when bytes are sent.
    SEL sentDataSel = @selector(objectFetcher:didSendBytes:totalBytesSent:totalBytesExpectedToSend:);
    [[self objectFetcher] setSentDataSelector:sentDataSel];
  }
}

之后在MyViewController.m中写完这样的

After that in MyViewController.m written like this

 [self.driveService setUploadProgressBlock:^(GTLServiceTicket *ticket, unsigned long long numberOfBytesRead, unsigned long long dataLength) {
  NSLog(@"uploading");

}];

以上NSLog永远不会因为这个原因而无法获得上传的数据字节。通过调试，我发现 uploadProgressBlock _ 始终显示为nil。可能这是我的块处理程序没有被执行。

Above NSLog never getting excused because of this I am unable to get uploaded data bytes. By debugging I come across as uploadProgressBlock_ always showing nil. may be this resone my block handler not getting executed.

如果我有任何错误，请建议我。
如果任何人有想法将数据的字节上传到谷歌驱动器的文件请建议我。您的建议对我的工作更有用。

Please suggest me if I did any mistake to work it out. If any one have idea to get the bytes of data uploaded to google drive for a file please suggest me. Your suggestions are more useful to my work.

提前致谢。

以下是获取上传进度信息的代码

Here is the code to get upload progress information

GTLServiceTicket *uploadTicket= [self.driveService executeQuery:query completionHandler:^(GTLServiceTicket *ticket,GTLDriveFile *updatedFile,NSError *error)
        {
            if (error == nil)
            {
                [self.delegate completedFileUploadingToGoogleDrive];
                NSError *fileDeletionError=nil;
                [[NSFileManager defaultManager] removeItemAtPath:absalutePath error:&fileDeletionError];
            } else
            {
                [self.delegate errorOccoredWhileUploadingToGoogleDrive:error];
            }
        }];

        [uploadTicket setUploadProgressBlock:^(GTLServiceTicket *ticket, unsigned long long totalBytesWritten, unsigned long long totalBytesExpectedToWrite) {
            [self.delegate uploadedFileInfoInKB:(float)totalBytesExpectedToWrite/1024 and:(float)totalBytesWritten/1024];
        }];

快乐编码!!

推荐答案

我已经成功使用了上传块回调...将它分配给你从 executeQuery获得的 GTLServiceTicket 对象方法。

I have succeeded in using the upload block callback... assign it to the GTLServiceTicket object you obtain from the executeQuery method.

示例：

GTLServiceTicket *uploadTicket =  [self.driveService executeQuery:query  completionHandler:^(GTLServiceTicket *ticket,  GTLDriveFile *insertedFile, NSError *error) 
                                           { // completion 
                                           }];


        [uploadTicket setUploadProgressBlock:^(GTLServiceTicket *ticket, unsigned long long totalBytesWritten, unsigned long long totalBytesExpectedToWrite) 
         {
             // progress
         }
