Post image base64 from iOS to twitter using request.js - twitter

Question

I am working on iOS. In my app user can take photo and upload from Library then it will store as image base64 in database. I want to post this image into Twitter when I select from database. But I always get error message below
{"errors":[{"code":189,"message":"Error creating status."}]}'
I have found a post below really familiar my problem but I still could not make it works.

Finally, I found this solution under this post:
Twitter image upload error : media parameter is missing
But one thing to note: make sure your image base64 is not contained full path. This driven me very crazy until I found it. Real example for me
var imageBase64 = data:image/jpeg;base64,4793748374837493749374937434b3b4398498343749374739479374739473947394347373479374334793748374837493749374937434b3b4398498343749374739479374739473947394347373479374334793748374837493749374937434b3b4398498343749374739479374739473947394347373479374334793748374837493749374937434b3b43984983437493747394793747394739473943473734793743...................................................................7979
It is not working. So I have to split as below:
var splitImageBase64 = imageBase64.split(",")[1];
Then it works.
I hope this may help someone else.
