我在打，我想在這我在谷歌驅動器存儲數據的應用程序的問題inbuild庫。 我已經生成了客戶端ID和客戶端密鑰。現在我無法找到谷歌驅動器的inbuild庫。如何獲得谷歌驅動器在iPhone SDK的
何地拖動GTL.xcodeproj，什麼是GTLDrive.h和GTLDrive_Sources.m。
如何使用和在哪裏得到這個????
這是我將使用代碼：
#import <UIKit/UIKit.h>
#import <MobileCoreServices/MobileCoreServices.h>
#import "GTMOAuth2ViewControllerTouch.h"
#import "GTLDrive.h"
@interface ViewController : UIViewController <UINavigationControllerDelegate, UIImagePickerControllerDelegate>
@property (nonatomic, retain) GTLServiceDrive *driveService;
@end
#import "ViewController.h"
static NSString *const kKeychainItemName = @"Google Drive Quickstart";
static NSString *const kClientID = @"YOUR_CLIENT_ID";
static NSString *const kClientSecret = @"YOUR_CLIENT_SECRET";
@implementation ViewController
@synthesize driveService;
- (void)viewDidLoad
{
[super viewDidLoad];
// Initialize the drive service & load existing credentials from the keychain if available
self.driveService = [[GTLServiceDrive alloc] init];
self.driveService.authorizer = [GTMOAuth2ViewControllerTouch authForGoogleFromKeychainForName:kKeychainItemName
clientID:kClientID
clientSecret:kClientSecret];
}
- (void)viewDidAppear:(BOOL)animated
{
// Always display the camera UI.
[self showCamera];
}

if ([UIImagePickerController isSourceTypeAvailable:UIImagePickerControllerSourceTypeCamera])
{
cameraUI.sourceType = UIImagePickerControllerSourceTypeCamera;
}
else
{
// In case we're running the iPhone simulator, fall back on the photo library instead.
cameraUI.sourceType = UIImagePickerControllerSourceTypePhotoLibrary;
if ([[UIDevice currentDevice] userInterfaceIdiom] == UIUserInterfaceIdiomPad)
{
[self showAlert:@"Error" message:@"Sorry, iPad Simulator not supported!"];
return;
}
};

cameraUI.delegate = self;
[self presentModalViewController:cameraUI animated:YES];
if (![self isAuthorized])
{
// Not yet authorized, request authorization and push the login UI onto the navigation stack.
[cameraUI pushViewController:[self createAuthController] animated:YES];
}
}
