using Twitter SDK to send tweet failed, but I'dont know why - ios

Question

I'm using Twitter SDK to loggin and tweet. Authenticate it's ok, but when use TWTRComposer with a simple text, the SDK callback return 'TWTRComposerResultDone', but the Simulator/Device show 'The tweet "text" cannot be sent because the connection to Twitter failed.
The debugger show 'plugin com.apple.share.Twitter.post invalidated' but everything aparently is correct.
Is there a bug or I forgot some thing.
My code:
TWTRComposer *composer = [[TWTRComposer alloc] init];
[composer setText:#"some text"];
[composer showWithCompletion:^(TWTRComposerResult result) {
if (result == TWTRComposerResultCancelled) {
NSLog(#"Tweet composition cancelled");
}
else {
NSLog(#"Sending Tweet!");
}
}];

Answer 1

Tweet Using SDK
1. Crearte App on twitter.developer
2. add twitter frameworks like TwitterCore.framework, TwitterKit.framework, Fabric.framework, TwitterKitResources.bundle
3. write below code in tweet button
[[Twitter sharedInstance] startWithConsumerKey:#"YourConsumerKey" consumerSecret:#"YourConsumerSecret"];
[Fabric with:#[[Twitter sharedInstance]]];
[[Twitter sharedInstance] logInWithCompletion:^(TWTRSession *session, NSError *error)
{
if (session)
{
NSLog(#"logged in user with id %#", session.userID);
TWTRComposer *composer = [[TWTRComposer alloc] init];
[composer setText:#"Enter Your Tweet Message"];
//[composer setImage:[UIImage imageNamed:#"fabric"]];
[composer showFromViewController:self completion:^(TWTRComposerResult result) {
if (result == TWTRComposerResultCancelled)
{
NSLog(#"Tweet composition cancelled");
}
else
{
NSLog(#"Sending Tweet!");
UIAlertView *warningAlert = [[UIAlertView alloc] initWithTitle:#"" message:#"Sent Tweet!" delegate:nil cancelButtonTitle:#"OK" otherButtonTitles:nil];
[warningAlert show];
}
}];
}
else
{
// log error
}
}];
