Upload file To Google Drive with Objective C

[Giordano Vicoli]

Hello everybody,

I am trying to upload a file to Google Drive in Objective c.

I am following the below example but I have the following error: insufficient permission.

What do I have to do? Please, help me.

Thanks and regards,

Giordano

NSData *fileData = [[NSFileManager defaultManager] contentsAtPath:@"files/photo.jpg"];

GTLRDrive_File *metadata = [GTLRDrive_File object];
metadata.name = @"photo.jpg";

GTLRUploadParameters *uploadParameters = [GTLRUploadParameters uploadParametersWithData:fileData
                                                                               MIMEType:@"image/jpeg"];
uploadParameters.shouldUploadWithSingleRequest = TRUE;
GTLRDriveQuery_FilesCreate *query = [GTLRDriveQuery_FilesCreate queryWithObject:metadata
                                                               uploadParameters:uploadParameters];
query.fields = @"id";
[driveService executeQuery:query completionHandler:^(GTLRServiceTicket *ticket,
                                                     GTLRDrive_File *file,
                                                     NSError *error) {
    if (error == nil) {
        NSLog(@"File ID %@", file.identifier);
    } else {
        NSLog(@"An error occurred: %@", error);
    }
}];

You snippet doesn't really say how your `driveService` was created, but it likely needs an `authorizer` set on it.
