Share videos on Twitter via iOS App - ios

Question

Is it possible to share a video using SLRequest ?
I'm able to share Images using the same
SLRequest *postRequest = [SLRequest requestForServiceType:SLServiceTypeTwitter requestMethod:SLRequestMethodPOST URL:requestURL parameters:message];
if (isImage)
{
NSData *data = UIImagePNGRepresentation(imgSelected);
[postRequest addMultipartData:data withName:#"media" type:#"image/png" filename:#"TestImage.png"];
}
postRequest.account = account;
[postRequest performRequestWithHandler:^(NSData *responseData, NSHTTPURLResponse *urlResponse, NSError *error)
{
if (!error)
{
NSLog(#"Upload Sucess !");
}
}];

I have been reading through the Twitter Video upload API documentation and its really pretty simple. You basically need to make 3 POST requests to their API. The video you are uploading is also limited to 15 MB in size.
Uploads using this endpoint require at least 3 calls, one to
initialize the request, which returns the media_id, one or more calls
to append/upload binary or base64 encoded data, and one last call to
finalize the upload and make the media_id usable with other resources.
So it works like this:
Request 1: Send a init request with the video size in bytes. This will return a Media ID number which we have to use in request 2 and 3.
Request 2: Use the returned Media ID number from request 1 to upload the video data.
Request 3: Once the video upload has finished, send a "FINALIZE" request back to the Twitter API. This lets the Twitter API know that all the chunks of the video file has finished uploading.
Note The Twitter API accepts video uploads in "chunks". So if your video file is quite big, you may want to split it up into more than one file and thus you will have to repeat "Request 2" more than once (not forgetting to increment the "segment_index" number each time).
I have had a go at coding this below. Try it and experiment around with it. I will update my answer later on to improve it too.
-(void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info {
// Assign the mediatype to a string
NSString *mediaType = [info objectForKey:UIImagePickerControllerMediaType];
// Check the media type string so we can determine if its a video
if ([mediaType isEqualToString:#"public.movie"]) {
NSURL *videoURL = [info objectForKey:UIImagePickerControllerMediaURL];
NSData *webData = [NSData dataWithContentsOfURL:videoURL];
// Get the size of the file in bytes.
NSString *yourPath = [NSString stringWithFormat:#"%", videoURL];
NSFileManager *man = [NSFileManager defaultManager];
NSDictionary *attrs = [man attributesOfItemAtPath:yourPath error: NULL];
UInt32 result = [attrs fileSize];
//[self tweetVideoStage1:webData :result];
[self tweetVideo:webData :result :1 :#"n/a"];
}
}
-(void)tweetVideo:(NSData *)videoData :(int)videoSize :(int)mode :(NSString *)mediaID {
NSURL *twitterVideo = [NSURL URLWithString:#"https://upload.twitter.com/1.1/media/upload.json"];
// Set the parameters for the first twitter video request.
NSDictionary *postDict;
if (mode == 1) {
postDict = #{#"command": #"INIT",
#"total_bytes" : videoSize,
#"media_type" : #"video/mp4"};
}
else if (mode == 2) {
postDict = #{#"command": #"APPEND",
#"media_id" : mediaID,
#"segment_index" : #"0",
#"media" : videoData };
}
else if (mode == 3) {
postDict = #{#"command": #"FINALIZE",
#"media_id" : mediaID };
}
SLRequest *postRequest = [SLRequest requestForServiceType:SLServiceTypeTwitter requestMethod:SLRequestMethodPOST URL:requestURL:twitterVideo parameters:postDict];
// Set the account and begin the request.
postRequest.account = account;
[postRequest performRequestWithHandler:^(NSData *responseData, NSHTTPURLResponse *urlResponse, NSError *error) {
if (!error) {
if (mode == 1) {
// Parse the returned data for the JSON string
// which contains the media upload ID.
NSMutableDictionary *returnedData = [NSJSONSerialization JSONObjectWithData:responseData options:NSJSONReadingMutableContainers error:&error]
NSString *tweetID = [NSString stringWithFormat:#"%#", [returnedData valueForKey:#"media_id_string"]];
[self tweetVideo:videoData :result :2 :tweetID];
}
else if (mode == 2) {
[self tweetVideo:videoData :result :3 :mediaID];
}
}
else {
NSLog(#"Error stage %d - %", mode, error);
}
}];
}
Update - Twitter API errors - https://dev.twitter.com/overview/api/response-codes
In answer to your first comment, error 503 means that the Twitter servers are overloaded and can't handle your request right now.
503 Service Unavailable The Twitter servers are up, but overloaded
with requests. Try again later.

Answer 2

I know how to upload video to twitter use the new API. And I have tried it, it works.
Please check this: https://github.com/liu044100/SocialVideoHelper
You just need to call this class method.
+(void)uploadTwitterVideo:(NSData*)videoData account:(ACAccount*)account withCompletion:(dispatch_block_t)completion;
Hope it can resolve your problem.
Best Regards.

Answer 3

Been looking for sharing video on Twitter solution with below features:
Support chunk upload
Built-in support for user's credential retrieval
Since I couldn't find one meeting my need, so I decided to write one.
https://github.com/mtrung/TwitterVideoUpload
I've been testing for awhile now and it works well for me.
Hope it helps,
Regards.

Answer 4

Try this based in #Dan answer. It not tested, but I think it can work.
Use Cocoa-pods: pod 'TwitterKit'
if you don't use Pods try with fabric
//for Extern call
//Mode is 1
//MediaId is 0
- (void)uploadTwitterVideo:(NSData*)videoData videoTitle:(NSString *)title desc:(NSString *)desc withMode:(int)mode mediaID:(NSString *)mediaID withCompletion:(dispatch_block_t)completion
{
NSString *twitterPostURL = #"https://upload.twitter.com/1.1/media/upload.json";
NSDictionary *postParams;
if (mode == 1) {
postParams = #{#"command": #"INIT",
#"total_bytes" : [NSNumber numberWithInteger: videoData.length].stringValue,
#"media_type" : #"video/mp4"};
} else if (mode == 2) {
postParams = #{#"command": #"APPEND",
#"media_id" : mediaID,
#"segment_index" : #"0"};
} else if (mode == 3) {
postParams = #{#"command": #"FINALIZE",
#"media_id" : mediaID };
} else if (mode == 4) {
postParams = #{#"status": desc,
#"media_ids" : #[mediaID]};
}
TWTRAPIClient *twitterInstance = [[Twitter sharedInstance] APIClient];
NSError *error;
NSURLRequest *requestTw = [twitterInstance URLRequestWithMethod:#"POST" URL:twitterPostURL parameters:postParams error:&error];
[twitterInstance sendTwitterRequest:requestTw completion:^(NSURLResponse * _Nullable response, NSData * _Nullable data, NSError * _Nullable connectionError) {
NSLog(#"HTTP Response: %li, responseData: %#", (long)response, [[NSString alloc] initWithData:data encoding:NSUTF8StringEncoding]);
if (error) {
NSLog(#"There was an error:%#", [error localizedDescription]);
} else {
if (mode == 1) {
NSMutableDictionary *returnedData = [NSJSONSerialization JSONObjectWithData:data options:NSJSONReadingMutableContainers error:&connectionError];
NSString *mediaIDResponse = [NSString stringWithFormat:#"%#", [returnedData valueForKey:#"media_id_string"]];
NSLog(#"stage one success, mediaID -> %#", mediaID);
[self uploadTwitterVideo:videoData videoTitle:title desc:desc withMode:2 mediaID:mediaIDResponse withCompletion:completion];
} else if (mode == 2) {
[self uploadTwitterVideo:videoData videoTitle:title desc:desc withMode:3 mediaID:mediaID withCompletion:completion];
} else if (mode == 3) {
[self uploadTwitterVideo:videoData videoTitle:title desc:desc withMode:4 mediaID:mediaID withCompletion:completion];
} else if (mode == 4) {
DispatchMainThread(^(){completion();});
}
}
}];
}
This API Works as follows.
- Login when application (twitter) is installed and when is not installed
- First priority take credential from setting
Check this case

Swift
Its very Simple.
First you need to sign in to your Twitter Account. Go to Phone Setting and click on twitter app and sign in.
Now Just Call this videoUpload func anywhere
Video or Chunked uploads Method Reference
Replace your video type/extension on that code
And Carefully read all twitter requirements.
var twitterAccount = ACAccount()
func videoUpload{
let path = Bundle.main.path(forResource: "file-Name", ofType:"mp4")
let filePath = path
var fileSize = UInt64()
do {
//return [FileAttributeKey : Any]
let attr = try FileManager.default.attributesOfItem(atPath: filePath!)
fileSize = attr[FileAttributeKey.size] as! UInt64
//if you convert to NSDictionary, you can get file size old way as well.
let dict = attr as NSDictionary
fileSize = dict.fileSize()
} catch {
print("Error: \(error)")
}
let accountStore = ACAccountStore()
let twitterAccountType = accountStore.accountType(withAccountTypeIdentifier: ACAccountTypeIdentifierTwitter)
accountStore.requestAccessToAccounts(with: twitterAccountType, options: nil) { (granted, error) in
if granted {
let accounts = accountStore.accounts(with: twitterAccountType)
if (accounts?.count)! > 0 {
self.twitterAccount = accounts?.last as! ACAccount
}}}
twitterAccount = Twitter.sharedInstance().sessionStore.session() as! ACAccount
uploadVideoToTwitter(videoURL: URL(string : path!)! as NSURL, fileSize: UInt32(fileSize))
}
func uploadVideoToTwitter(videoURL:NSURL,fileSize: UInt32) {
if let videoData = NSData(contentsOfFile: videoURL.path!){
self.tweetVideoInit(videoData: videoData, videoSize: Int(fileSize))
}
}
func tweetVideoInit(videoData:NSData,videoSize:Int) {

Answer 6

I was able to upload video to twitter successfully!
Below are steps referred from twitter docs:
Request for twitter account
accountStore.requestAccessToAccounts(with: twitterAccountType,options:nil){(granted, error) in
POST media/upload (INIT)
params["command"] = "INIT"
params["total_bytes"] = String(videoData.length)
params["media_type"] = "video/mov"
POST media/upload (APPEND)
params["command"] = "APPEND"
params["media_id"] = mediaId
params["segment_index"] = String(chunk)
POST media/upload (FINALIZE)
params["command"] = "FINALIZE"
params["media_id"] = mediaId
POST media/upload
params["status"] = twitterDescription
params["media_ids"] = mediaId
Here is twitter doc link https://dev.twitter.com/rest/media/uploading-media.html
