Recently, when I was writing a swift project, I needed to use the third party login of facebook, googleplus, Twitter. Another colleague who worked on the oc project told me that his shareSDK third party login had a pit that I couldn't solve, so I didn't use sharesdk, but the landlord was a person who pursued it and plunged into sharesdk.

Step 1: Get sharesdk appkey.

How to get appkey: http://bbs.mob.com/forum.php?mod=viewthread&tid=8212&extra=page%3D1

Step 2: Download sharesdk

Download link: http://www.mob.com/downloadDetail/ShareSDK/ios Note: sharesdk's swift version is actually practiced by bridging the oc version

Step 3: Integrate sdk, because the landlord only needs to integrate facebook, googleplus, Twitter, third party login, the bridge file is as follows, step 5 of the official document has a small pit.

Integrated tutorials: http://wiki.mob.com/swift-call-sharesdk/ 

Bridge file code:

#ifndef MoveApp_Bridging_Header_h
#define MoveApp_Bridging_Header_h


#import <ShareSDK/ShareSDK.h>
#import <ShareSDKConnector/ShareSDKConnector.h>
#import <FacebookConnector/FacebookConnector.h>
#import <GooglePlusConnector/SSDKGooglePlusControllerStyle.h>

#endif /* MoveApp_Bridging_Header_h */

Step 4: Configure the AppDelegate.swift file and code it directly:

func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplicationLaunchOptionsKey : Any]? = nil) -> Bool {

  ShareSDK.registerApp("Your sharesdkappkey", activePlatforms: [
            SSDKPlatformType.typeFacebook.rawValue,
            SSDKPlatformType.typeTwitter.rawValue,
            SSDKPlatformType.typeGooglePlus.rawValue,
            ],
            
         onImport: { (platform : SSDKPlatformType) in
            switch platform
            {
            default:
                break
            }
        }) { (platform : SSDKPlatformType, appInfo : NSMutableDictionary?) in
            
            switch platform
            {
                
            case SSDKPlatformType.typeFacebook:
                //Set up Facebook Application information, where authType Set to Use Only SSO Formal authorization
                
                appInfo?.ssdkSetupFacebook(byApiKey: "107704292745179",
                                           appSecret : "38053202e1a5fe26c80c753071f0b573",
                                           authType : SSDKAuthTypeBoth)
                
            case SSDKPlatformType.typeTwitter:
                //Set up Twitter Application information
                appInfo?.ssdkSetupTwitter(byConsumerKey: "LRBM0H75rWrU9gNHvlEAA2aOy",
                                          consumerSecret : "gbeWsZvA9ELJSdoBzJ5oLKX0TU09UOwrzdGfo9Tg7DjyGuMe8G",
                                          redirectUri : "http://www.baidu.com")
                //Set up gooleplus Application information
            case SSDKPlatformType.typeGooglePlus:
                appInfo?.ssdkSetupGooglePlus(byClientID: "232554794995.apps.googleusercontent.com", clientSecret: "Can not fill", redirectUri: "http://localhost");
                break
                
            default:
                break
            }
            
        }

     return true
    }

    }

Part 5: Controller clicks button to authorize login to get token

func OAuth(sender: UIButton) {
        
        //To grant authorization
        ShareSDK.authorize(SSDKPlatformType.Types of third parties needed, settings: nil, onStateChanged: { (state : SSDKResponseState, user : SSDKUser?, error : Error?) -> Void in
            
            switch state{
                
            case SSDKResponseState.success: print("Authorized success,User information is\(user)\n ----- The certificate of authorization is\(user?.credential)")
            case SSDKResponseState.fail:    print("privilege grant failed,Wrong description:\(error)")
            case SSDKResponseState.cancel:  print("Operation cancelled")
                
            default:
                break
            }
        })
    
}

End of the whole course

Note: At this time, the social platform web authorization window still does not have the following possibilities:

redirectUri differs from the callback address of the third-party developer's application, or is misconfigured

Or the social platform appkey and secrt have errors.
