我正在使用适用于iPhone的Google Drive SDK并尝试在“TestAudio”文件夹中上传音频文件。如果未在Google云端硬盘中创建“TestAudio”文件夹，则首先创建该文件夹，之后我的音频应仅存储到该文件夹​​。除文件夹创建外，每件事都在工作。任何哥们请帮忙吗？

I am using below code for upload audio file.

我使用下面的代码上传音频文件。

GTLUploadParameters *uploadParameters = nil;

NSString *soundFilePath = [[NSBundle mainBundle]
                           pathForResource:@"honey_bunny_new"
                           ofType:@"mp3"];

if (soundFilePath) {
    NSData *fileContent = [[NSData alloc] initWithContentsOfFile:soundFilePath];
    uploadParameters = [GTLUploadParameters uploadParametersWithData:fileContent MIMEType:@"audio/mpeg"];
}

self.driveFile.title = self.updatedTitle;
GTLQueryDrive *query = nil;
if (self.driveFile.identifier == nil || self.driveFile.identifier.length == 0) {
    // This is a new file, instantiate an insert query.
    query = [GTLQueryDrive queryForFilesInsertWithObject:self.driveFile
                                        uploadParameters:uploadParameters];
} else {
    // This file already exists, instantiate an update query.
    query = [GTLQueryDrive queryForFilesUpdateWithObject:self.driveFile
                                                  fileId:self.driveFile.identifier
                                        uploadParameters:uploadParameters];
}
UIAlertView *alert = [DrEditUtilities showLoadingMessageWithTitle:@"Saving file"
                                                         delegate:self];

[self.driveService executeQuery:query completionHandler:^(GTLServiceTicket *ticket,
                                                          GTLDriveFile *updatedFile,
                                                          NSError *error) {
[alert dismissWithClickedButtonIndex:0 animated:YES];
if (error == nil) {
    self.driveFile = updatedFile;
    self.originalContent = [self.textView.text copy];
    self.updatedTitle = [updatedFile.title copy];
    [self toggleSaveButton];
    [self.delegate didUpdateFileWithIndex:self.fileIndex
                                    driveFile:self.driveFile];
    [self doneEditing:nil];
} else {
    NSLog(@"An error occurred: %@", error);
    [DrEditUtilities showErrorMessageWithTitle:@"Unable to save file"
                                           message:error.description
                                          delegate:self];
}
}];

I don't see your code to create a folder, but I was having the same problem with folder creation myself. As you know, the mimeType must be "application/vnd.google-apps.folder". I ran into assert failures if the NSData parameter to uploadParametersWithData was nil. So I tried a zero length NSData object and that failed. Using a 1 byte NSData object also failed. The trick is to call queryForFilesUpdateWithObject with uploadParameters:nil. Then the folder creation works fine. I also discovered that the Objective-C code shown at the end of:

我没有看到你的代码创建一个文件夹，但我自己也遇到了与文件夹创建相同的问题。如您所知，mimeType必须是“application / vnd.google-apps.folder”。如果uploadParametersWithData的NSData参数为nil，我遇到断言失败。所以我尝试了一个零长度的NSData对象，但失败了。使用1字节的NSData对象也失败了。诀窍是使用uploadParameters：nil调用queryForFilesUpdateWithObject。然后文件夹创建工作正常。我还发现最后显示的Objective-C代码：

is incorrect. The file.parents should be as follows:

是不正确的。 file.parents应如下所示：

GTLDriveParentReference *parentRef = [GTLDriveParentReference object];
parentRef.identifier = parentID;
if (parentID.length>0) file.parents = [NSArray arrayWithObjects:parentRef,nil];
