How to post a tweet with new api in ios app ? just adding the authorisation header is not working

[jackripred]

Since the twitter api is changed my app no longer posts tweet. Every thing was working fine before and according to new API only request pattern should change ? All the other stuff initialising the engine and rest should be same ?

And the method for sharing should be modified, so I modified it but getting “Bad Authentication 215”. All the token info and other things I got it from the authentication header generated from twitter itself:

• (void) shareOnTwitter
  {
  NSString *urlString = [NSString stringWithFormat:@“https://api.twitter.com/1.1/statuses/update.json”];

  NSURL *url = [NSURL URLWithString:urlString];

  NSMutableURLRequest *request = [[NSMutableURLRequest alloc] initWithURL:url];

  [request setHTTPMethod:@“POST”];

  NSMutableDictionary *dict = [[NSMutableDictionary alloc] init];

  [dict setValue:@“check Check CHECK” forKey:@“status”];

  [dict setValue:@"-- - - - - -" forKey:@“oauth_consumer_key”];

  [dict setValue:@"- - - - - - -" forKey:@“oauth_nonce”];

  [dict setValue:@"- - - - - - -" forKey:@“oauth_signature”];

  [dict setValue:@“HMAC-SHA1” forKey:@“oauth_signature_method”];

  [dict setValue:@"- - - - - - -" forKey:@“oauth_timestamp”];

  [dict setValue:@"- - - - - - -" forKey:@“oauth_token”];

  [dict setValue:@“1.0” forKey:@“oauth_version”];

  NSString *jsonString = [dict JSONRepresentation];

  NSData *jsonData = [NSData dataWithBytes:[jsonString UTF8String] length:jsonString.length];

  [request setHTTPBody:jsonData];
