在Swift中請求TWTRShareEmailViewController（Fabric Twitter SDK）的用戶Twitter郵件

Question

我想請求用戶的Twitter郵件。在https://dev.twitter.com/twitter-kit/ios/request-email上，我們可以看到Obj-C中的代碼，但我在Swift中需要它，而我無法翻譯它。有誰知道如何，請嗎？

這裏的對象 - 代碼：

if ([[Twitter sharedInstance] session]) { 
    TWTRShareEmailViewController* shareEmailViewController = 
       [[TWTRShareEmailViewController alloc] 
       initWithCompletion:^(NSString* email, NSError* error) { 
     NSLog(@"Email %@, Error: %@", email, error); 
    }]; 
    [self presentViewController:shareEmailViewController 
              animated:YES 
              completion:nil]; 
} else { 
    // TODO: Handle user not signed in (e.g. 
    // attempt to log in or show an alert) 
} 

感謝您的幫助。

這應該上述Objective-C的大致翻譯成斯威夫特：

if (Twitter.sharedInstance().session() != nil) { 
     if let shareEmailViewController = TWTRShareEmailViewController(completion: { 
      (email: String!, error: NSError!) in 
      if (email != nil) { 
       print("\(email)") 
      } else { 
       print("\(error)") 
      } 
     }) { 
      self.presentViewController(shareEmailViewController, animated: true, completion: nil) 
     } 
    } else { 
     print("User not logged in") 
    }
