Cannot compose tweets with Twitter Kit 3

问题:

I followed instruction from https://dev.twitter.com/twitterkit/ios/compose-tweets to compose tweets via my Object C app for iOS 11

// Objective-C TWTRComposer *composer = [[TWTRComposer alloc] init];  [composer setText:@"just setting up my Twitter Kit"]; [composer setImage:[UIImage imageNamed:@"twitterkit"]];  // Called from a UIViewController [composer showFromViewController:self completion:^(TWTRComposerResult result) {     if (result == TWTRComposerResultCancelled) {         NSLog(@"Tweet composition cancelled");     }     else {         NSLog(@"Sending Tweet!");     } }]; 

However, after clicking Connect button at [Connect your account] screen, it turned back app without composing tweet (Twitter logged in already). It seems showFromViewController didn't run. Anyone had the same problem?

First of all get read/write permission on Twitter for your app.

    if ([[Twitter sharedInstance].sessionStore hasLoggedInUsers]) {   NSString *twitterLoggedInInfo = [[NSUserDefaults standardUserDefaults] objectForKey:@"TwitterLoggedInInfo"];    if (![twitterLoggedInInfo isEqualToString:@"v3"]) {     NSString *currentUserID = [Twitter sharedInstance].sessionStore.session.userID;     [[Twitter sharedInstance].sessionStore logOutUserID:currentUserID];      [[NSUserDefaults standardUserDefaults] setObject:@"v3" forKey:@"TwitterLoggedInInfo"];     [[NSUserDefaults standardUserDefaults] synchronize];      [[Twitter sharedInstance] logInWithCompletion:^(TWTRSession *session, NSError *error) {       if (session) {         TWTRComposerViewController *composer = [[TWTRComposerViewController alloc] initWithInitialText:tweetText image:tweetImage videoURL:nil];         [self presentViewController:composer animated:YES completion:nil];       }     }];   } else {     if (![twitterLoggedInInfo isEqualToString:@"v3"]) {       [[NSUserDefaults standardUserDefaults] setObject:@"v3" forKey:@"TwitterLoggedInInfo"];       [[NSUserDefaults standardUserDefaults] synchronize];     }      TWTRComposerViewController *composer = [[TWTRComposerViewController alloc] initWithInitialText:tweetText image:tweetImage videoURL:nil];     [self presentViewController:composer animated:YES completion:nil];   }   } else {     [[Twitter sharedInstance] logInWithCompletion:^(TWTRSession *session, NSError *error) {       if (session) {         TWTRComposerViewController *composer = [[TWTRComposerViewController alloc] initWithInitialText:tweetText image:tweetImage videoURL:nil];         [self presentViewController:composer animated:YES completion:nil];       }     }];   } 

TwitterLoggedInInfo key checking your exist only read permissions users, I mean using this key is an optional.
