Facebook SDK Swift - 使用未声明的标识符

Question

我正在Use of undeclared identifier使用我使用的每个Facebook对象

遵循本教程: 教程:如何在FACEBOOK SDK 4.1.X for SWIFT中分享

但我有以下错误:

我通过cocoapods添加了Facebook框架:

pod 'FBSDKCoreKit'
pod 'FBSDKShareKit'

它已成功安装

我添加了桥接头

#ifndef Bridging_Header_h
#define Bridging_Header_h

#import <FBSDKCoreKit/FBSDKCoreKit.h>
#import <FBSDKShareKit/FBSDKShareKit.h>

#endif /* Bridging_Header_h */

桥接头连接:

我已经配置了我的.plist

<key>CFBundleURLTypes</key>
    <array>
        <dict>
            <key>CFBundleURLSchemes</key>
            <array>

            </dict>
        </dict>
    </dict>

这是代码:

let content : FBSDKShareLinkContent = FBSDKShareLinkContent()
        content.contentURL = NSURL(string: "<INSERT STRING HERE>")
        content.contentTitle = "<INSERT STRING HERE>"
        content.contentDescription = "<INSERT STRING HERE>"
        content.imageURL = NSURL(string: "<INSERT STRING HERE>")

        let button : FBSDKShareButton = FBSDKShareButton()
        button.shareContent = content
        button.frame = CGRectMake((UIScreen.mainScreen().bounds.width - 100) * 0.5, 50, 100, 25)
        self.view.addSubview(button)

use_frameworks!
pod 'ChameleonFramework/Swift'
pod 'GBDeviceInfo'

按命令保存文件并安装或更新pod:

pod install / pod update

接下来,您应该添加一般设置框架:
