Google Drive SDK Sharing A File

Question

I am currently trying to use the google drive API for IOS to create a folder, put a file in the folder, and then share the file. Creating the folder, and putting the file in the folder works, but the sharing feature does not. When I log onto the email address that i shared the file with, it does not show up. Could someone please help me figure out where the issue would arise in the Objective -c code below.

The order the methods are called is initSetup where the folder is created, then in initsetup,uploadToFolder is called, an in uploadToFolder, the file is shared.

#import "userSetUp.h"
#import <GoogleSignIn/GoogleSignIn.h>
@import GoogleAPIClientForREST;


 @implementation userSetUp
 NSString *folderID;
-(id) initWithDriveService:(GTLRDriveService *)driveService{
self = [ super init];
if(self){
    self.driveService = driveService;
}
return self;
}
 - (void) initSetup{



GTLRDrive_File *metadata = [GTLRDrive_File object];
metadata.name = @"AName";
metadata.mimeType = @"application/vnd.google-apps.folder";
GTLRDriveQuery_FilesCreate *query = [GTLRDriveQuery_FilesCreate queryWithObject:metadata
                                                               uploadParameters:nil];
query.fields = @"id";
[_driveService executeQuery:query completionHandler:^(GTLRServiceTicket *ticket,
                                                     GTLRDrive_File *file,
                                                     NSError *error) {
    if (error == nil) {
        folderID =  file.identifier;
        //[self shareToDrive:file.identifier];
        //printf("the folder id is" + file.identifier )
        [self uploadToFolder: file.identifier];
        NSLog(@" FOLDER File ID %@", file.identifier);
    } else {
        NSLog(@"An error occurred: %@", error);
    }
}];




}

Don't know the ios codes exactly but I think as long as you specify the

  "emailAddress": "[email protected]",
  "role": "reader",
  "type": "user"

in Permissions.create, it should be work.
