I want to post a photo to twitter from my iOS app. I can post a tweet without media but when i am trying to attach media it throws an error.
I am following twitter documentation and according to that first I need to upload media to https://upload.twitter.com/1.1/media/upload.json and then I will be able to attach it with the tweet using media-id.
here is my code for uploading media.
App is crashing at URLRequestWithMedthod call.
Help me to resolve issue.
UIImage *image = [UIImage imageNamed:@"shareit.png"];
NSData *imageData = UIImageJPEGRepresentation(image, 0.7);
NSString *statusesShowEndpoint = @"https://upload.twitter.com/1.1/media/upload.json";
NSDictionary *params = @{@"media" : imageData};
NSError *clientError;
NSURLRequest *request = [[[Twitter sharedInstance] APIClient]
URLRequestWithMethod:@"POST"
URL:statusesShowEndpoint
parameters:params
error:&clientError];
if (request) {
[[[Twitter sharedInstance] APIClient]
sendTwitterRequest:request
completion:^(NSURLResponse *response,
NSData *data,
NSError *connectionError) {
if (data) {
// handle the response data e.g.
NSError *jsonError;
NSDictionary *json = [NSJSONSerialization
JSONObjectWithData:data
options:0
error:&jsonError];
NSLog(@"%@",json);
}
else {
NSLog(@"Error: %@", connectionError);
}
}];
}
else {
NSLog(@"Error: %@", clientError);
}
Well it was pretty simple. All was missing is conversion of imagedata into base64EncodedString. Here is the solution.
NSString *media = @"https://upload.twitter.com/1.1/media/upload.json";
NSData *imageData = UIImageJPEGRepresentation(image, 0.9);
NSString *imageString = [imageData base64EncodedStringWithOptions:0];
NSError *error;
NSURLRequest *request = [[[Twitter sharedInstance] APIClient] URLRequestWithMethod:@"POST" URL:media parameters:@{@"media":imageString} error:&error];
[[[Twitter sharedInstance] APIClient] sendTwitterRequest:request completion:^(NSURLResponse *urlResponse, NSData *data, NSError *connectionError) {
NSError *jsonError;
NSDictionary *json = [NSJSONSerialization
JSONObjectWithData:data
options:0
error:&jsonError];
NSLog(@"Media ID : %@",[json objectForKey:@"media_id_string"]);
// Post tweet With media_id
}];
Completing the Saani's answer
// Post tweet With media_id
mediaID = [json objectForKey:@"media_id_string"];
client = [[Twitter sharedInstance] APIClient];
message = @{@"status": title, @"wrap_links": @"true", @"media_ids": mediaID};
NSURLRequest *request = [client URLRequestWithMethod:@"POST" URL:@"https://api.twitter.com/1.1/statuses/update.json" parameters:message error:&error];
[client sendTwitterRequest:request completion:^(NSURLResponse * _Nullable response, NSData * _Nullable data, NSError * _Nullable connectionError) {
if (connectionError) {
NSLog(@"error %@",[connectionError localizedDescription]);
} else {
NSError *jsonError;
NSDictionary *json = [NSJSONSerialization JSONObjectWithData:data options:0 error:&jsonError];
NSLog(@"json Finish! %@",json);
}
}];
Sharing the swift 2.2 (Xcoe 7.3.2) code if anyone is still looking for help.
let client = TWTRAPIClient.init(userID:<Twitter_User_Id_Here>)
let imgData = UIImageJPEGRepresentation(UIImage(named:"Home")!, 0.7)
client.uploadMedia(imgData!, contentType: "image/jpeg", completion: {(media_ids,error) in
if error == nil{
//prints the media_ids in String.
//Pass them into the params of status update params ["media_ids":<MEDIA_ID>]
print(media_ids)
}
else{
print(error?.localizedDescription)
}
})
To Send with status update.
let request = client.URLRequestWithMethod("POST", URL: "https://api.twitter.com/1.1/statuses/update.json", parameters: ["status":"Hello World","media_ids":<Media_Ids_Here>], error: nil)
client.sendTwitterRequest(request, completion: {
(response,data,error)in
if error == nil {
print(data)
}
else{
print("Error")
}
})
}
