不能用Twitter 3撰写tweet

Question

我遵循https://dev.twitter.com/twitterkit/ios/compose-tweets的指令，通过对象C应用程序为iOS 11编写tweet

// 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!");
    }
}];

然而，点击“连接你的帐户”屏幕上的“连接”按钮后，它在没有写推特的情况下返回了应用程序(Twitter已经登录)。看来showFromViewController没有跑。有人也有同样的问题吗？

首先，在Twitter上为您的应用程序获取读写权限。

    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键检查您只存在的读取权限用户，我的意思是使用这个键是一个可选的。
