I’m updating an app from v1 API to v1.1. Got the authentication working fine, and am able to do account/verify_credentials.json to confirm it. But I am unable to send a tweet using statuses/update.json.
This is Obj-C code using the GTMOAuth framework. After the authentication dance, this part works fine:
- (void) getTwitterInfo
{
NSURL *url = [NSURL URLWithString: @"https://api.twitter.com/1.1/account/verify_credentials.json"];
NSMutableURLRequest *request = [NSMutableURLRequest requestWithURL:url];
[myAuth authorizeRequest: request];
GTMHTTPFetcher* myFetcher = [GTMHTTPFetcher fetcherWithRequest:request];
[myFetcher beginFetchWithCompletionHandler:^(NSData *retrievedData, NSError *error)
{
if (error != nil)
{
NSLog(@"StokerXTwitter Verification error: %@", error);
}
else
{
NSDictionary *results = [[[[NSString alloc] initWithData: retrievedData encoding:NSUTF8StringEncoding] autorelease] JSONValue];
self.twitterUserName = [results objectForKey: @"name"];
self.twitterHandle = [results objectForKey: @"screen_name"];
NSLog(@"StokerXTwitter Verification Successful for %@ (@%@)", twitterUserName, twitterHandle);
[self sendTweet: @"StokerXTwitter Verification Successful"];
}
[self updateUI];
}];
}

This part fails:
