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，我设法使一个Facebook登录按钮工作。但是，它是从SDK自动分配按钮图像，它不可自定义（因为它没有在故事板上创建），所以我无法使用我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按钮并自定义它从那里如何做到这一点？

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进行登录

Login with custom button and access token.

在Facebook sdk中获取用户信息4.x

Get user info in facebook sdk 4.x

@IBAction func btnFBLoginPressed(sender: AnyObject) {
    var fbLoginManager : FBSDKLoginManager = FBSDKLoginManager()
    fbLoginManager .logInWithReadPermissions(["email"], 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)
            }
        })
    }
}
