ios - 无需 SLCompose 或任何类型的对话即可与 Facebook 共享

Question

import Foundation
class FacebookShareService {
    private var shareImage : UIImage!
    private var shareDescription : String?

    init(image : UIImage, description : String?) {
        self.shareImage = image
        self.shareDescription = description
    }

    func start() {
        if FBSDKAccessToken.currentAccessToken() != nil && FBSDKAccessToken.currentAccessToken().permissions.contains("publish_actions"){
            self.startShareToFacebook()
        } else {
            getPublishPermission({ (error) -> () in
                let alert = UIAlertView(title: "Error!!!", message: error.domain, delegate: self, cancelButtonTitle: "Close")
                alert.show()
            }, success: { () -> () in
                self.startShareToFacebook()
            })
        }
    }

    private func startShareToFacebook() {
        let dict : NSMutableDictionary = NSMutableDictionary()
        if let des = self.shareDescription
        {
            dict.setValue(des, forKey: "caption")

        }
        dict.setValue(self.shareImage, forKey: "source")
        FBSDKGraphRequest(graphPath: "me/photos", parameters: dict as [NSObject : AnyObject], HTTPMethod: "POST").startWithCompletionHandler { (conn : FBSDKGraphRequestConnection!, response : AnyObject!, error :NSError!) -> Void in
            if error != nil {
                print("Can't use graphApi me/photos")
                let alert = UIAlertView(title: "Error!!!", message: error.domain, delegate: self, cancelButtonTitle: "Close")
                alert.show()
            } else {
                let alert = UIAlertView(title: "", message: "Successful!!!", delegate: self, cancelButtonTitle: "Close")
                alert.show()
            }
        }
    }

    private func getPublishPermission(fail : (error : NSError)->(),success:()->()) {
        let loginManager : FBSDKLoginManager = FBSDKLoginManager()
        loginManager.loginBehavior = FBSDKLoginBehavior.Native
        loginManager.logInWithPublishPermissions(["publish_actions"], handler: { (loginResult:FBSDKLoginManagerLoginResult!, error :NSError!) -> Void in
            if error != nil {
                print("Can't login with permission public_action")
                fail(error: error)
            } else {
                if let result = loginResult {
                    if loginResult.isCancelled {
                        print("Can not get permisson")
                        fail(error: NSError(domain: "Can not get permisson", code: 100000, userInfo: nil))
                    } else {
                        if let permissions = loginResult.grantedPermissions {
                            if permissions.contains("publish_actions") {
                                success()
                            } else {
                                print("Publish actions is not allowed")
                                let error : NSError = NSError(domain: "Publish actions is not allowed", code: 1000, userInfo: nil)
                                fail(error : error)
                            }
                        } else {
                            print("Publish actions is not allowed")
                            let error : NSError = NSError(domain: "Publish actions is not allowed", code: 1000, userInfo: nil)
                            fail(error : error)
                        }
                    }

                } else {
                    print("Can not get permisson")
                    fail(error: NSError(domain: "Can not get permisson", code: 100000, userInfo: nil))
                }
            }
        })

    }
}

以上代码不适用于任何类型的解决方案或需要任何类型的现成源代码。在此代码中，他们使用的是旧 SDK，与新 SDK 不兼容。我正在使用最新的 ios SDK。热切地等待有人的帮助。

FBSDKLoginManager *login = [[FBSDKLoginManager alloc] init];
        [FBSDKProfile enableUpdatesOnAccessTokenChange:YES];
        login.loginBehavior = FBSDKLoginBehaviorSystemAccount;
        [login logInWithPublishPermissions:@[@"publish_actions"]  handler:^(FBSDKLoginManagerLoginResult result, NSError error) {
            if (error){

            } else if (result.isCancelled){

            } else{
                if ([result.grantedPermissions containsObject:@"email"]){
                    if ([FBSDKAccessToken currentAccessToken]){
                        [self funcGetUserFBInfo];
                    }
                }
            }
        }];

为了分享

FBSDKShareLinkContent *content = [[FBSDKShareLinkContent alloc] init];
                content.contentURL = [NSURL URLWithString:@"http://www.indianic.com/"];
                [FBSDKShareDialog showFromViewController:self withContent:content delegate:self];
                UIPasteboard *pasteboard = [UIPasteboard generalPasteboard];
                pasteboard.string = @"“Love only grows by sharing. You can only have more for yourself by giving it away to others”";
