I get this error because i have not set parameter in proper format. Now i use this code and working fine.

NSString *trimmedText=[NSString stringWithFormat:@"%@",txt_comment.text];

NSURL *url=[NSURL URLWithString: @"https://api.twitter.com/1/statuses/update.xml"];
NSMutableDictionary *params = [NSMutableDictionary dictionaryWithCapacity:0];
[params setObject:trimmedText forKey:@"status"];
NSString *body = [self _queryStringWithBase:nil parameters:params prefixed:NO];

NSData* requestData = [body dataUsingEncoding: NSUTF8StringEncoding];


OAMutableURLRequest *request = [[[OAMutableURLRequest alloc] initWithURL:url consumer: appDelegate.consumer token: appDelegate.accessToken realm: nil signatureProvider: nil] autorelease];  

[request setHTTPMethod:@"POST"];
[request setHTTPBody:requestData];
OADataFetcher *fetcher = [[OADataFetcher alloc] init];

[fetcher fetchDataWithRequest:request
                     delegate:self
            didFinishSelector:@selector(accessTokenTicket_post:didFinishWithData:)
              didFailSelector:@selector(accessTokenTicket:didFailWithError:)];
