Swift 2 Xcode7.1 Facebook SDK + 自訂Facebook Button

一、下載Facebook SDK

• FacebookSDKs-iOS-20151111.zip

二、Xcode開新專案
編輯專案下的info.plist
新增以下設定
Facebook developer key 記得先去申請 Facebook Developer

<key>CFBundleURLTypes</key>
<array>
  <dict>
    <key>CFBundleURLSchemes</key>
    <array>
      <string>fb{your-app-id}</string>
    </array>
  </dict>
</array>
<key>FacebookAppID</key>
<string>{your-app-id}</string>
<key>FacebookDisplayName</key>
<string>{your-app-name}</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>

三、將.framework檔放入
先new Group，名稱為Frameworks
在將FBSDKCoreKit.framework，FBSDKLoginKit.framework，FBSDKShareKit.framework放入Frameworks裡

四、寫程式
1.AppDelegate.swift

import UIKit
import CoreData
import FBSDKCoreKit

@UIApplicationMain
class AppDelegate: UIResponder, UIApplicationDelegate {

    var window: UIWindow?


    func application(application: UIApplication,
        openURL url: NSURL,
        sourceApplication: String?,
        annotation: AnyObject) -> Bool {
            return FBSDKApplicationDelegate.sharedInstance().application(
                application,
                openURL: url,
                sourceApplication: sourceApplication,
                annotation: annotation)
    }
.....
}

2.ViewController.swift

import UIKit
import FBSDKCoreKit
import FBSDKShareKit
import FBSDKLoginKit

class ViewController: UIViewController {
    let fbLoginManager : FBSDKLoginManager = FBSDKLoginManager()
    override func viewDidLoad() {
        super.viewDidLoad()
    }
    
    override func didReceiveMemoryWarning() {
        super.didReceiveMemoryWarning()
        // Dispose of any resources that can be recreated.
    }
    @IBAction func loginAction(sender: AnyObject) {
        
        fbLoginManager.logInWithReadPermissions(["email"],fromViewController: self.parentViewController, handler: { (result, error) -> Void in
            if (error == nil){
                let fbloginresult : FBSDKLoginManagerLoginResult = result
                if(fbloginresult.grantedPermissions.contains("email"))
                {
                    self.getFBUserData()
                    self.fbLoginManager.logOut()
                }
            }
        })
        
    }
    func getFBUserData(){
        if((FBSDKAccessToken.currentAccessToken()) != nil){
            FBSDKGraphRequest(graphPath: "me", parameters: ["fields": "id, name, first_name, last_name, picture.type(large), email"]).startWithCompletionHandler({ (connection, result, error) -> Void in
                if (error == nil){
                    print(result)
                }
            })
        }
    }
    @IBAction func logoutAction(sender: AnyObject) {
        
        fbLoginManager.logOut()
    }
    
}

打完收功...
