Swift QQ Authorized login and access to personal information (user information) examples

Now many apps or websites support using QQ account to log in. This article demonstrates how to implement a third-party login for QQ, as well as access to the user's personal information after login.

1, Tencent Open Platform registration, and SDK configuration (this can be official to find)

2, login authorization, and obtain user information

(1) Click the "Log in and get user Information" button

(2) The program will automatically jump to QQ, display the login page (the page will show the required authorization)

(3) After the successful login will automatically return to the original app. In this sample we get the user information and print it out after the login is successful

Super.viewdidload ()

_tencentoauth = Tencentoauth.init (appId: "1105212016", anddelegate:self)
}

Login button click
@IBAction func Login (sender:anyobject) {
Set Permissions List
Let permissions = ["Get_user_info", "Get_simple_userinfo"];

To exit login, revoke authorization. You only need to invoke the logout () method of the Tencentoauth object.

_tencentoauth.logout (self)
