then implemented code in sa_oauthtwitterengine because i'm using oauth method post text or image twitter because application deployment target starting form 3.0(ios,ipod), try method.

now problem how create code send image twitter message.

i try send image twitter using below type

[_engine sendupdate:@"http://www.prepare-community.com/sharefiles/index-fr.jpg"]; 

i got connection error means 401 error.

could please send me how send image twitter using above code?

here solution image uploading using new twitter api update_with_media. using api can upload image direct way twitter account. above _uploadimage code should placed first in sa_oauthtwitter engine .m file , decalred in .h file.

and make small correct placed filenamed=1.jpg instead of 1.png.

and put below code in mgtwitterengine.m class. here code below

    - (nsstring *)_uploadimage:(uiimage *)image withstatus:(nsstring *)status {      return [self _uploadimage:image withstatus:status requesttype:mgtwitterimagerequest responsetype:mgtwitterstatuses]; } 

and use code upload image twitter. is,

[_engine _uploadimage:yourpicture withstatus:yourstatus];

hope work you....
