There are a lot of GData YouTube tutorials on how to upload a Video in an iOS App, but I didn't find one showing how to comment on a Video. So I read on the reference-page, just tried and so on but didn't find anything!
Does anyone know how to comment on a Video in an iOS App using the GData API?
Thanks
Use this methods in comment button
GDataEntryYouTubeVideo *video = (GDataEntryYouTubeVideo *)arrayData;
[self addCommentTitle:#"comment" text:commentField.text toVideo:video];
- (void)addCommentTitle:(NSString *)commentTitle
text:(NSString *)commentContent
toVideo:(GDataEntryYouTubeVideo *)entry {
GDataComment *commentObj = [entry comment];
GDataFeedLink *feedLink = [commentObj feedLink];
NSURL *feedURL = [feedLink URL];
if (feedURL) {
// fetch the comment feed for the video
GDataServiceGoogleYouTube *service = [self youTubeService];
[service setYouTubeDeveloperKey:devKey];
[service setAuthToken:[self getRequestToken]];
[service fetchFeedWithURL:feedURL completionHandler:^(GDataServiceTicket *ticket, GDataFeedBase *commentFeed,NSError *error) {
if (error == nil) {
GDataEntryYouTubeComment *newCommentEntry = [GDataEntryYouTubeComment commentEntry];
[newCommentEntry addContentValueDeclaration];
[newCommentEntry setTitleWithString:commentTitle];
[newCommentEntry setContentWithString:commentContent];
NSString *subString = [videoString substringWithRange: NSMakeRange(0, [videoString rangeOfString: #"?"].location)];
NSString *last=[subString lastPathComponent];
NSString *ss=#"http://gdata.youtube.com/feeds/api/videos/";
NSString *idd=#"/comments";
NSString *com=[NSString stringWithFormat:#"%#%#%#",ss,last,idd];
NSURL *postURL = [NSURL URLWithString:com ];
[service fetchEntryByInsertingEntry:newCommentEntry
forFeedURL:postURL
completionHandler:^(GDataServiceTicket *ticket, GDataEntryBase *entry, NSError *error) {
// callback
if (error == nil) {
NSLog(#"url.: succeeded ");
}
}];
}
}];
}
}

In my project wanna have a flow like this:
Users record short videos -> they upload the videos on my channel -> end
To achive this result i'm trying to work with the new Google APIs Client Library for Objective-C for REST. It has a poor documentation and the examples are for mac only. Anyway after many errors this is my code:
- (void)doAuthWithoutCodeExchange:(OIDServiceConfiguration *)configuration
clientID:(NSString *)clientID
clientSecret:(NSString *)clientSecret {
NSURL *redirectURI = [NSURL URLWithString:kRedirectURI];
// builds authentication request
OIDAuthorizationRequest *request =
[[OIDAuthorizationRequest alloc] initWithConfiguration:configuration
clientId:clientID
clientSecret:clientSecret
scopes:#[ OIDScopeOpenID, OIDScopeProfile ]
redirectURL:redirectURI
responseType:OIDResponseTypeCode
additionalParameters:nil];
// performs authentication request
AppDelegate *appDelegate = (AppDelegate *) [UIApplication sharedApplication].delegate;
[self logMessage:#"Initiating authorization request %#", request];
appDelegate.currentAuthorizationFlow =
[OIDAuthorizationService presentAuthorizationRequest:request
presentingViewController:self
callback:^(OIDAuthorizationResponse *_Nullable authorizationResponse,
NSError *_Nullable error) {
if (authorizationResponse) {
OIDAuthState *authState =
[[OIDAuthState alloc] initWithAuthorizationResponse:authorizationResponse];
[self setAuthState:authState];
[self logMessage:#"Authorization response with code: %#",
authorizationResponse.authorizationCode];
// could just call [self tokenExchange:nil] directly, but will let the user initiate it.
OIDTokenRequest *tokenExchangeRequest =
[_authState.lastAuthorizationResponse tokenExchangeRequest];
[self logMessage:#"Performing authorization code exchange with request [%#]",
tokenExchangeRequest];
[OIDAuthorizationService performTokenRequest:tokenExchangeRequest
callback:^(OIDTokenResponse *_Nullable tokenResponse,
NSError *_Nullable error) {
if (!tokenResponse) {
[self logMessage:#"Token exchange error: %#", [error localizedDescription]];
} else {
[self logMessage:#"Received token response with accessToken: %#", tokenResponse.accessToken];
}
[_authState updateWithTokenResponse:tokenResponse error:error];
GTMAppAuthFetcherAuthorization *gtmAuthorization =
[[GTMAppAuthFetcherAuthorization alloc] initWithAuthState:authState];
// Sets the authorizer on the GTLRYouTubeService object so API calls will be authenticated.
self.youTubeService.authorizer = gtmAuthorization;
// Serializes authorization to keychain in GTMAppAuth format.
[GTMAppAuthFetcherAuthorization saveAuthorization:gtmAuthorization
toKeychainForName:kGTMAppAuthKeychainItemName];
[self uploadVideoFile];
}];
} else {
[self logMessage:#"Authorization error: %#", [error localizedDescription]];
}
}];
}
This method cause this flow:
app send user to google login page in safari -> user log with his credentials -> after login, user is redirect back to my app -> the block success call the method UploadVideo.
This part of the flow seems to work correctly, i obtain a valid token as the log says. The second part is the video upload that consist in two main methods:
- (void)uploadVideoFile {
// Collect the metadata for the upload from the user interface.
// Status.
GTLRYouTube_VideoStatus *status = [GTLRYouTube_VideoStatus object];
status.privacyStatus = #"public";
// Snippet.
GTLRYouTube_VideoSnippet *snippet = [GTLRYouTube_VideoSnippet object];
snippet.title = #"title";
NSString *desc = #"description";
if (desc.length > 0) {
snippet.descriptionProperty = desc;
}
NSString *tagsStr = #"tags";
if (tagsStr.length > 0) {
snippet.tags = [tagsStr componentsSeparatedByString:#","];
}
GTLRYouTube_Video *video = [GTLRYouTube_Video object];
video.status = status;
video.snippet = snippet;
[self uploadVideoWithVideoObject:video
resumeUploadLocationURL:nil];
}
- (void)uploadVideoWithVideoObject:(GTLRYouTube_Video *)video
resumeUploadLocationURL:(NSURL *)locationURL {
NSURL *fileToUploadURL = [NSURL fileURLWithPath:self.VideoUrlCri.path];
NSError *fileError;
NSLog(#"step");
if (![fileToUploadURL checkPromisedItemIsReachableAndReturnError:&fileError]) {
NSLog(#"exit");
return;
}
// Get a file handle for the upload data.
NSString *filename = [fileToUploadURL lastPathComponent];
NSString *mimeType = [self MIMETypeForFilename:filename
defaultMIMEType:#"video/mp4"];
GTLRUploadParameters *uploadParameters =
[GTLRUploadParameters uploadParametersWithFileURL:fileToUploadURL
MIMEType:mimeType];
uploadParameters.uploadLocationURL = locationURL;
GTLRYouTubeQuery_VideosInsert *query =
[GTLRYouTubeQuery_VideosInsert queryWithObject:video
part:#"snippet,status"
uploadParameters:uploadParameters];
query.executionParameters.uploadProgressBlock = ^(GTLRServiceTicket *ticket,
unsigned long long numberOfBytesRead,
unsigned long long dataLength) {
NSLog(#"upload progress");
};
GTLRYouTubeService *service = self.youTubeService;
_uploadFileTicket = [service executeQuery:query
completionHandler:^(GTLRServiceTicket *callbackTicket,
GTLRYouTube_Video *uploadedVideo,
NSError *callbackError) {
if (callbackError == nil) {
NSLog(#"uploaded");
} else {
NSLog(#"error %#",callbackError);
}
}];
}
- (NSString *)MIMETypeForFilename:(NSString *)filename
defaultMIMEType:(NSString *)defaultType {
NSString *result = defaultType;
NSString *extension = [filename pathExtension];
CFStringRef uti = UTTypeCreatePreferredIdentifierForTag(kUTTagClassFilenameExtension,
(__bridge CFStringRef)extension, NULL);
if (uti) {
CFStringRef cfMIMEType = UTTypeCopyPreferredTagWithClass(uti, kUTTagClassMIMEType);
if (cfMIMEType) {
result = CFBridgingRelease(cfMIMEType);
}
CFRelease(uti);
}
return result;
}
I obtain a 403 error in NSLog(#"error %#",callbackError); and i can't see error details because the are something like :
data=<7b226572 726f7222 3a7b2265 72726f72 73223a5b 7b22646f 6d61696e 223a2267 6c6f6261 6c222c22 72656173 6f6e223a 22696e73 75666669 ... 61676522 3a22496e 73756666 69636965 6e742050 65726d69 7373696f 6e227d7d>}
In google api console i have created a Client Oauth for my application bundle and an API key, i use those values for my connection, it seems they works correctly because i obtain a valid token. Anyway, there someone who can help me or point me in the right direction about this error? Or there someone who knows a working example about a video upload for IOS and not for MAC ? There something weird in my code? I can't find any help in documentation or google
I tried to download file from google drive API since 3 day without success. I used this https://developers.google.com/drive/ios/devguide/files#reading_files.
But I can't understand what I need to put in *drive and *file?
I tried :
GTLDriveFile *file = #"fileText.txt"; (or I tried the url of my file on google drive...) The guide don't explain... And I didn't find real example.
GTLServiceDrive *drive = ...;
GTLDriveFile *file = ...;
NSString *url = [NSString stringWithFormat:#"https://www.googleapis.com/drive/v3/files/%#?alt=media",
file.identifier]
GTMSessionFetcher *fetcher = [drive.fetcherService fetcherWithURLString:url];
[fetcher beginFetchWithCompletionHandler:^(NSData *data, NSError *error) {
if (error == nil) {
NSLog(#"Retrieved file content");
// Do something with data
} else {
NSLog(#"An error occurred: %#", error);
}
}];
So I had search other code like but no one explain what I need to put in drive and file:
how to download file from google drive using objective c? (just this say it's url)
Google drive api download file for iOS
IOS: How to Download Google Docs files using ios google drive sdk API?
SOLUTION :
I had a problem of authorization with my scope, solved by total access to drive. I changed the scope (in quickstart code, look : "- (GTMOAuth2ViewControllerTouch *)createAuthController...")
-->NSArray *scopes = [NSArray arrayWithObjects:kGTLAuthScopeDrive, nil];
For download (inspired by quickstart example) :
// self.service is my GTLServiceDrive
// When the view appears, ensure that the Drive API service is authorized, and perform API calls.
- (void)viewDidAppear:(BOOL)animated {
if (!self.service.authorizer.canAuthorize) {
// Not yet authorized, request authorization by pushing the login UI onto the UI stack.
[self presentViewController:[self createAuthController] animated:YES completion:nil];
} else {
NSString *urltest = [NSString stringWithFormat:#"https://www.googleapis.com/drive/v3/files/%#?alt=media", identifier_file]; //the ID of my file in a string identifier_file
GTMSessionFetcher *fetcher = [self.service.fetcherService fetcherWithURLString:urltest]; // the request
// receive response and play it in web view:
[fetcher beginFetchWithCompletionHandler:^(NSData *data, NSError *errorrr) {
if (errorrr == nil) {
NSLog(#"Retrieved file content");
[webView_screen loadData:data MIMEType:#"application/pdf" textEncodingName:#"UTF-8" baseURL:nil]; //my file is a pdf
[webView_screen reload];
} else {
NSLog(#"An error occurred: %#", errorrr);
}
}];
}
}
If you want to save on the phone, you can look the Bala's code.
First fetch the file from Drive
driveFiles = [[NSMutableArray alloc] init];
for (GTLDriveFile *file in files.items) {
if ([file.mimeType isEqualToString:#"application/vnd.google-apps.folder"]) {
} else {
NSString *fileExtension = file.fileExtension;
if (fileExtension) {
if ([fileExtension isEqualToString:#"pdf"]) {
[driveFiles addObject:file];
}
}
}
}
And GTLDriveFile pass the object that you have in the array
GTLDriveFile *file=[driveFiles objectAtIndex:indexPath.row];
This is the code for download the file
NSString *link;
if (file.webContentLink) {
link = file.webContentLink;
} else if (file.embedLink) {
link = file.embedLink;
} else {
UIAlertView *alert = [[UIAlertView alloc] initWithTitle:#"ERROR" message:#"File has no downloadable link" delegate:nil cancelButtonTitle:#"Ok" otherButtonTitles:nil, nil];
[alert show];
}
if (link) {
NSString *downloadUrl = file.downloadUrl;
GTMHTTPFetcher *fetcher = [self.driveService.fetcherService fetcherWithURLString:downloadUrl];
//async call to download the file data
[fetcher beginFetchWithCompletionHandler:^(NSData *data, NSError *error) {
if (error == nil) {
if (data) {
NSString *dirPath = [self directoryPathForSavingFile];
NSString *filePath = [dirPath stringByAppendingPathComponent:file.title];
[self saveFileJSONData:data forFileName:filePath withCompletionHandler:^(BOOL successStatus) {
// Adding skip attribute to avoid data sinking in iCloud
BOOL path = [[NSFileManager defaultManager] fileExistsAtPath:filePath];
if (path) {
NSLog(#"filePath %#", filePath);
}
}];
}
} else {
NSLog(#"An error occurred: %#", error);
}
}];
}
Code for Directory path for save the file
- (NSString *)directoryPathForSavingFile:(NSString *)directoryName {
NSString *applicationDirectory = [NSHomeDirectory() stringByAppendingPathComponent:#"Documents"];
applicationDirectory = [applicationDirectory stringByAppendingPathComponent:directoryName];
return applicationDirectory;
}
i want to upload video to youtube channel.i tried with following Code.the bellow code work to upload video but the problem is, i can't attach its information(Video Title,Description & Tags).after uploading it shows only video title as a "unknown" and no tags or description .i've seen CodingTofu , Dev7Dev Blog- iOS Sample Code and many other Q&A but i can't understand where i'm making mistake.
NSString* title = video.title;
NSString* description = video.videoDescription;
NSData* data = video.data;
NSMutableArray* tags = video.tags.mutableCopy;
GTLYouTubeVideo *yVideo = [GTLYouTubeVideo object];
GTLYouTubeVideoSnippet *snippet = [GTLYouTubeVideoSnippet alloc];
snippet.title = title;
snippet.descriptionProperty = description;
[tags addObject:DEFAULT_KEYWORD];
NSString* tag = [UploadController generateKeywordFromPlaylistId:UPLOAD_PLAYLIST];
[tags addObject:tag];
snippet.tags = tags;
GTLYouTubeVideoStatus *status = [GTLYouTubeVideoStatus alloc];
status.privacyStatus = #"public";
GTLUploadParameters *uploadParameters = [GTLUploadParameters uploadParametersWithData:data MIMEType:#"video/*"];
GTLQueryYouTube *query = [GTLQueryYouTube queryForVideosInsertWithObject:yVideo part:#"snippet,status" uploadParameters:uploadParameters];
service.uploadProgressBlock = ^(GTLServiceTicket* ticket, unsigned long long totalBytesUploaded, unsigned long long totalBytesExpectedToUpload){
CGFloat percentage = totalBytesUploaded/totalBytesExpectedToUpload;
NSLog(#"\nUploaded percentage %%(%0.2f)",percentage);
};
[service executeQuery:query completionHandler:^(GTLServiceTicket *ticket, GTLYouTubeVideo *insertedVideo, NSError *error) {
//[waitIndicator dismissWithClickedButtonIndex:0 animated:YES];
if (error == nil)
{
NSLog(#"File ID: %#", insertedVideo.identifier);
return;
}
else
{
NSLog(#"An error occurred: %#", error);
return;
}
}];
tell me if you need any further Details
thank you.
sorry for my bad English.
i got the Mistake,
in above code, i have to add
GTLYouTubeVideo *yVideo = [GTLYouTubeVideo object];
GTLYouTubeVideoStatus *status = [GTLYouTubeVideoStatus alloc];
GTLYouTubeVideoSnippet *snippet = [GTLYouTubeVideoSnippet alloc];
*******
*******
*******
yVideo.snippet = snippet;//This part i forgot to add in my code
yVideo.status = status;//This part i forgot to add in my code
[service executeQuery........
This Might be helpful to someone who facing same issue.
In YouTube v2, user can report a video as inappropriate through following way,
-(void)flagInappropriateVideo: (NSString*)inVideoId
{
GDataServiceGoogleYouTube *service = [self youtubeService];
[service fetchEntryWithURL:videoEntryFetchURL completionHandler:^(GDataServiceTicket *ticket, GDataEntryBase *entry, NSError *error) {
NSError *err = error;
NSURL *complaintsLink = [[(GDataEntryYouTubeVideo*)entry complaintsLink] URL];
if(err || !entry || !complaintsLink)
{
if(!err)
err = [NSError errorWithDomain: UNKNOWN_ERROR_DOMAIN code: UNKNOWN_ERROR_CODE userInfo: nil];
}
else
{
GDataEntryYouTubeComplaint *complaint = [GDataEntryYouTubeComplaint complaintEntry];
[service fetchEntryByInsertingEntry:complaint
forFeedURL: complaintsLink
delegate:self
didFinishSelector:#selector(complaintTicket:finishedWithEntry:error:)];
}
}];
}
- (void)complaintTicket:(GDataServiceTicket *)ticket
finishedWithEntry:(GDataEntryBase *)entry
error:(NSError *)error
{
// handle completion
}
I did not find any equivalent classes and methods for GDataEntryYouTubeVideo and complaintsLink also the GDataEntryYouTubeComplaint to report a complaintEntry in YouTube V3.
I would like to know whether this is depreciated or is there any other way to do this? Please do help,Thanks!
You can see them from GDataObjectiveC client.
I have added youtube api v3 using google api's objective-C client in my app to upload video to youtube. Testers of the app (in different country) reports that they are unable to upload video to youtube. Video uploading fails after reaching to 100 % progress with backend error. Where as I am not facing that issue in my end here in India. Testers also confirms that youtube video upload is working fine when uploaded using youtube ios app or some different app. They also tried uploading videos from multiple accounts but with same result.
The error log from device console is:
Error Domain=com.google.GTLJSONRPCErrorDomain Code=-32099 "The operation couldn’t be completed. (Backend Error)" UserInfo=0x2438c380 {error=Backend Error, GTLStructuredError=GTLErrorObject 0x27ea3990: {message:"Backend Error" code:-32099 data:[1]}, NSLocalizedFailureReason=(Backend Error)}
and my code that I am using to upload video to youtube is:
GTMOAuth2Authentication *auth = [GTMOAuth2ViewControllerTouch authForGoogleFromKeychainForName:YoutubeOAuthKeyChain clientID:GoogleAPIClientID clientSecret:GoogleAPIClientSecret];
if (!auth) {
[self signInToGoogle];
}else{
if ([auth canAuthorize] && auth.userEmail) {
//Force the api to refresh access token if needed
[auth authorizeRequest:Nil completionHandler:^(NSError *error) {
dispatch_async(dispatch_get_main_queue(), ^{
if (!error) {
NSLog(#"Youtube: App authorized. Uploading video now");
self.youTubeService.authorizer = auth;
GTLYouTubeVideoStatus *status = [GTLYouTubeVideoStatus object];
status.privacyStatus = #"public";
GTLYouTubeVideoSnippet *snippet = [GTLYouTubeVideoSnippet object];
snippet.title = _captionTextView.text;
snippet.descriptionProperty = #"This is a test video";
GTLYouTubeVideo *video = [GTLYouTubeVideo object];
video.status = status;
video.snippet = snippet;
NSString *filename = [_moviePath lastPathComponent];
NSFileHandle *fileHandle = [NSFileHandle fileHandleForReadingAtPath:_moviePath];
if (fileHandle) {
NSString *mimeType = [self MIMETypeForFilename:filename
defaultMIMEType:#"video/mp4"];
GTLUploadParameters *uploadParameters = [GTLUploadParameters uploadParametersWithFileHandle:fileHandle MIMEType:mimeType];

//uploadParameters.shouldSendUploadOnly = YES;
GTLQueryYouTube *query = [GTLQueryYouTube queryForVideosInsertWithObject:video part:#"snippet,status" uploadParameters:uploadParameters];
GTLServiceYouTube *service = self.youTubeService;
GTLServiceTicket *ticket = [service executeQuery:query completionHandler:^(GTLServiceTicket *ticket, id object, NSError *error) {
dispatch_async(dispatch_get_main_queue(), ^{
if (!error) {
NSLog(#"Youtube video upload completed ");
}else{
NSLog(#"error completing request with error: %#", error);
}
});
}];
[ticket setUploadProgressBlock:^(GTLServiceTicket *ticket, unsigned long long totalBytesWritten, unsigned long long totalBytesExpectedToWrite) {
float progress = ((float)totalBytesWritten / (float)totalBytesExpectedToWrite) * 100.0f;
NSLog(#"%f %% uploaded");
}];
}
}else{
//Error authorizing the request
NSLog(#"error authorizing request with error: %#", error);
}
});
}];
}else{
//Refresh access token

}
}
This issue started just 2 weeks ago. I have no idea if this is a server side issue of some issue with my app. Has anyone also have the same issue?
