如何在iphone sdk中获取谷歌驱动器的inbuild库
我遇到了一个问题，我想制作一个应用程序，我将数据存储在Google云端硬盘中。 我已经生成了客户端ID和客户端密钥。 现在你无法找到谷歌硬盘的inbuild库。
在哪里拖动GTL.xcodeproj以及什么是GTLDrive.h和GTLDrive_Sources.m。
如何使用这个和在哪里得到这个？
这是我将使用的代码：
#import #import #import "GTMOAuth2ViewControllerTouch.h" #import "GTLDrive.h" @interface ViewController : UIViewController @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]; } - (void)showCamera { UIImagePickerController *cameraUI = [[UIImagePickerController alloc] init]; 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.mediaTypes = [[NSArray alloc] initWithObjects: (NSString *) kUTTypeImage, nil]; cameraUI.allowsEditing = YES; 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]; } } // Handle selection of an image - (void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info { UIImage *image = [info valueForKey:UIImagePickerControllerOriginalImage]; [self dismissModalViewControllerAnimated:YES]; [self uploadPhoto:image];} // Handle cancel from image picker/camera. - (void)imagePickerControllerDidCancel:(UIImagePickerController *)picker{ [self dismissModalViewControllerAnimated:YES];} // Helper to check if user is authorized - (BOOL)isAuthorized{ return [((GTMOAuth2Authentication *)self.driveService.authorizer) canAuthorize]; } // Handle completion of the authorization process, and updates the Drive service // with the new credentials. - (void)viewController:(GTMOAuth2ViewControllerTouch *)viewController finishedWithAuth:(GTMOAuth2Authentication *)authResult error:(NSError *)error { if (error != nil) { [self showAlert:@"Authentication Error" message:error.localizedDescription]; self.driveService.authorizer = nil; } else { self.driveService.authorizer = authResult; } } // Uploads a photo to Google Drive - (void)uploadPhoto:(UIImage*)image { NSDateFormatter *dateFormat = [[NSDateFormatter alloc] init]; [dateFormat setDateFormat:@"'Quickstart Uploaded File ('EEEE MMMM d, YYYY h:mm a, zzz')"]; GTLDriveFile *file = [GTLDriveFile object]; file.title = [dateFormat stringFromDate:[NSDate date]]; file.descriptionProperty = @"Uploaded from the Google Drive iOS Quickstart"; file.mimeType = @"image/png"; NSData *data = UIImagePNGRepresentation((UIImage *)image); GTLUploadParameters *uploadParameters = [GTLUploadParameters uploadParametersWithData:data MIMEType:file.mimeType]; GTLQueryDrive *query = [GTLQueryDrive queryForFilesInsertWithObject:file uploadParameters:uploadParameters]; UIAlertView *waitIndicator = [self showWaitIndicator:@"Uploading to Google Drive"]; [self.driveService executeQuery:query completionHandler:^(GTLServiceTicket *ticket, GTLDriveFile *insertedFile, NSError *error) { [waitIndicator dismissWithClickedButtonIndex:0 animated:YES]; if (error == nil) { NSLog(@"File ID: %@", insertedFile.identifier); [self showAlert:@"Google Drive" message:@"File saved!"]; } else { NSLog(@"An error occurred: %@", error); [self showAlert:@"Google Drive" message:@"Sorry, an error occurred!"]; } }]; } // Helper for showing a wait indicator in a popup - (UIAlertView*)showWaitIndicator:(NSString *)title { UIAlertView *progressAlert; progressAlert = [[UIAlertView alloc] initWithTitle:title message:@"Please wait..." delegate:nil cancelButtonTitle:nil otherButtonTitles:nil]; [progressAlert show]; UIActivityIndicatorView *activityView; activityView = [[UIActivityIndicatorView alloc] initWithActivityIndicatorStyle:UIActivityIndicatorViewStyleWhite]; activityView.center = CGPointMake(progressAlert.bounds.size.width / 2, progressAlert.bounds.size.height - 45); [progressAlert addSubview:activityView]; [activityView startAnimating]; return progressAlert; } // Helper for showing an alert - (void)showAlert:(NSString *)title message:(NSString *)message { UIAlertView *alert; alert = [[UIAlertView alloc] initWithTitle: title message: message delegate: nil cancelButtonTitle: @"OK" otherButtonTitles: nil]; [alert show]; } @end 我从以下链接获得了此代码： https ： //developers.google.com/drive/quickstart-ios
使用此video ，他如何跟踪步骤以及他拖动GTL.xcodeproj的位置。 非常仔细地遵循步骤。
