FacebookSDK(4.1.x) 自定义登录 UI 按钮 - Swift(1.2) [英] FacebookSDK(4.1.x) Custom Login UI Button - Swift(1.2)

问题描述

遵循本教程，我已经设法使 Facebook 登录按钮正常工作.但是，它会从 SDK 自动分配按钮图像，并且无法自定义(因为它不是在 Storyboard 上创建的)，因此我无法改用自己的按钮图像或文本.

Following this tutorial, I have managed to make a Facebook Login Button working. However, it is assigning the button image automatically from the SDK and it is not customisable (as it is not getting created on Storyboard), so I am unable to use my own button image or text instead.

我相信这部分代码(在 ViewDidLoad 中)正在分配按钮:

I believe this part of the code (in ViewDidLoad) is assigning the button:

        let loginView : FBSDKLoginButton = FBSDKLoginButton()
        self.view.addSubview(loginView)
        loginView.center = self.view.center
        loginView.readPermissions = ["public_profile", "email"]
        loginView.delegate = self

我需要做的是在 Storyboard 上创建一个 @IBOutlet 按钮并从那里对其进行自定义.我该怎么做?

What I need to do is creating a @IBOutlet Button on Storyboard and customise it from there. How can I do that?

推荐答案

使用自定义按钮和访问令牌登录.

Login with custom button and access token.

在 facebook sdk 4.x 中获取用户信息

Get user info in facebook sdk 4.x

@IBAction func btnFBLoginPressed(sender: AnyObject) {
    var fbLoginManager : FBSDKLoginManager = FBSDKLoginManager()
    fbLoginManager.logInWithReadPermissions(["email"], fromViewController: self, handler: { (result, error) -> Void in
        if (error == nil){
            var fbloginresult : FBSDKLoginManagerLoginResult = result
            if(fbloginresult.grantedPermissions.contains("email"))
            {
                self.getFBUserData()
                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){
                println(result)
            }
        })
    }
}
