Facebook SDK Swift - 使用未声明的标识符 [英] Facebook SDK Swift - Use of undeclared identifier

问题描述

我正在获得对我使用的每个Facebook对象使用未声明的标识符

按照本教程：

我已经通过Cocapod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 * / 
  

桥接头已连接：

我配置了我的.plist

 < key> CFBundleURLTypes< / key> 
< array> 
< dict> 
< key> CFBundleURLSchemes< / key> 
< array> 
< string> fb *****< / string> 
< / array> 
< / dict> 
< / array> 
< key> FacebookAppID< / key> 
< string> *****< / string> 
< key> FacebookDisplayName< / key> 
< string> *****< / string> 
< key> NSAppTransportSecurity< / key> 
< dict> 
< key> NSExceptionDomains< / key> 
< dict> 
< key> facebook.com< / key> 
< dict> 
< key> NSIncludesSubdomains< / key> <真/> 
< key> NSThirdPartyExceptionRequiresForwardSecrecy< / key> <假/> 
< / dict> 
< key> fbcdn.net< / key> 
< dict> 
< key> NSIncludesSubdomains< / key> <真/> 
< key> NSThirdPartyExceptionRequiresForwardSecrecy< / key> <假/> 
< / dict> 
< key> akamaihd.net< / key> 
< dict> 
< key> NSIncludesSubdomains< / key> <真/> 
< key> NSThirdPartyExceptionRequiresForwardSecrecy< / key> <假/> 
< / dict> 
< / dict> 
< / dict> 
  

以下是代码：

  let content：FBSDKShareLinkContent = FBSDKShareLinkContent（）
 content.contentURL = NSURL（string：< INSERT STRING HERE>）
 content.contentTitle =&INSERT STRING此处>中
 content.contentDescription =< INSERT STRING HERE> 
 content.imageURL = NSURL（string：< INSERT STRING HERE>）
 
 let按钮：FBSDKShareButton = FBSDKShareButton（）
 button.shareContent = content 
 button.frame = CGRectMake（（UIScreen.mainScreen（）。bounds.width  -  100）* 0.5，50，100，25）
 self.view.addSubview（button）
  

解决方案

如果您使用Pods并且您的项目位于Swift，则不需要将头文件从pod Bridging_Header_h
将所需的SDK导入到swift文件中，如下所示：

  import FBSDKCoreKit 
 import FBSDKLoginKit 
 import FBSDKShareKit 
  

I am getting Use of undeclared identifier for every Facebook Object I use

Following this tutorial: TUTORIAL: HOW TO SHARE IN FACEBOOK SDK 4.1.X FOR SWIFT

But I've got the following error:

I've added Facebook framework via cocoapods:

pod 'FBSDKCoreKit'
pod 'FBSDKShareKit'

And it was installed successfully

I've added bridging header

#ifndef Bridging_Header_h
#define Bridging_Header_h

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

#endif /* Bridging_Header_h */

The bridging header is connected:

I've configured my .plist

<key>CFBundleURLTypes</key>
    <array>
        <dict>
            <key>CFBundleURLSchemes</key>
            <array>
                <string>fb*****</string>
            </array>
        </dict>
    </array>
    <key>FacebookAppID</key>
    <string>*****</string>
    <key>FacebookDisplayName</key>
    <string>*****</string>
    <key>NSAppTransportSecurity</key>
    <dict>
        <key>NSExceptionDomains</key>
        <dict>
            <key>facebook.com</key>
            <dict>
                <key>NSIncludesSubdomains</key> <true/>
                <key>NSThirdPartyExceptionRequiresForwardSecrecy</key> <false/>
            </dict>
            <key>fbcdn.net</key>
            <dict>
                <key>NSIncludesSubdomains</key> <true/>
                <key>NSThirdPartyExceptionRequiresForwardSecrecy</key>  <false/>
            </dict>
            <key>akamaihd.net</key>
            <dict>
                <key>NSIncludesSubdomains</key> <true/>
                <key>NSThirdPartyExceptionRequiresForwardSecrecy</key> <false/>
            </dict>
        </dict>
    </dict>

Here is the code:

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)

解决方案

If you use Pods and your project is on Swift you don't need to import headers from pods to Bridging_Header_h It's suficient to import needed SDK to you swift file like:

import FBSDKCoreKit
import FBSDKLoginKit
import FBSDKShareKit
