I am trying to integrate "tumblr" into my application.I am able to get the access token successfully. But, when I try to post, I am getting the following error
{"meta":{"status":401,"msg":"Not Authorized"},"response":[]}
I am using the OAuthConsumer client for iOS, which I have pulled if from MGTwitterEngine.
This is what I have tried.
#import "ViewController.h"
#define consumer_key @"u9iZvT8KIlrTtUrh3vUeXXXXXXXXXXXXXAfgpThGyom8Y6MKKCnU"
#define consumer_secret @"xfA10mQKmALlpsnrFXXXXXXXXXXXXXXXXXXXXXXXXXX"
#define request_token_url @"http://www.tumblr.com/oauth/request_token"
#define access_token_url @"http://www.tumblr.com/oauth/access_token"
#define authorize_url @"http://www.tumblr.com/oauth/authorize?oauth_token=%@"
#define base_url @"http://api.tumblr.com/v2/user/XXXXXXXXXXXXX.tumblr.com/info"

Whats the mistake I am making here? Why I am getting that error? Did I follow the steps properly?
Please XXX out your consumer_key and consumer_secret to avoid unwanted use of them. Code wise there are a few things you might want to look for here.
Are you able to use an oauth 'GET' request such as "http://api.tumblr.com/v2/user/info"? If you can receive a successful 'GET' request then your access token is valid and you can look at how you're sending your post parameters.
Make sure you are passing in your parameters as HTTP Body as well as signature parameters. Correct parameter ordering is likely provided by the library.
NSString *postbody = @"body=myBodyText&type=text";
[oRequest setHTTPBody:[postbody dataUsingEncoding:NSUTF8StringEncoding allowLossyConversion:TRUE]];
