FBSDKShareDialog在发布时取消

Question

我在代码

中创建了一个FBSDKShareDialog

- (void)shareWithFacebookDialog;
{  
  FBSDKShareLinkContent* content = [[FBSDKShareLinkContent alloc] init];
  content.contentURL = [NSURL URLWithString:@"Path Redacted"];
  content.contentTitle = @"Title Redacted";
  content.contentDescription = @"Description Redacted";

  FBSDKShareDialog* dialog = [[FBSDKShareDialog alloc] init];
  [dialog setMode:FBSDKShareDialogModeNative];
  [dialog setShareContent:content];
  [dialog setDelegate:self];
  [dialog setFromViewController:self];
  [dialog show];
}

对话框启动，所有信息都正确

但是只要点击Post，对话框就会关闭，并且会调用取消委托。

- (void)sharerDidCancel:(id<FBSDKSharing>)sharer;

有没有人见过这个？找到了克服它的方法吗？

Answer 1

用这个

替换你的代码

- (void)shareWithFacebookDialog;
{  
    FBSDKShareLinkContent content = [[FBSDKShareLinkContent alloc]init];
    content.contentURL = [NSURL URLWithString:@"https://www.google.com"];
    content.contentTitle = @"ContentTitle";
    content.contentDescription = @"ContentDescription";
    [FBSDKShareDialog showFromViewController:self
                                 withContent:content
                                    delegate:self];
}

告诉我它是否有效。

当我尝试在登录后立即调用该方法时，发生了这种情况。

FBSDKLoginManager *login = [[FBSDKLoginManager alloc] init];
    [login logInWithPublishPermissions:@[@"publish_actions"] handler:^(FBSDKLoginManagerLoginResult *result, NSError *error) {
        if (error || result.isCancelled) {

        } else {
            [self shareWithFacebookDialog];
        }
    }];

如果我在没有登录的情况下调用它（它应该已经有有效的令牌），它就可以工作。

if ([FBSDKAccessToken currentAccessToken]) {
    [self shareWithFacebookDialog];
}

I had the same problem: Facebook SDK share always returns sharerDidCancel

My error was in the AppDelegate method:

here is a link with the solution http://jitu1990.blogspot.it/2015/05/share-with-facebook-from-ios-app.html

And here is the code

- (BOOL)application:(UIApplication *)application openURL:(NSURL* )url sourceApplication:(NSString *)sourceApplication annotation:(id)annotation {   
    return [[FBSDKApplicationDelegate sharedInstance] application:application
                                                      openURL:url sourceApplication:sourceApplication annotation:annotation];
}

- (void)applicationDidBecomeActive:(UIApplication *)application {
    [FBSDKAppEvents activateApp];
}

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
    return [ [FBSDKApplicationDelegate sharedInstance] application :application
             didFinishLaunchingWithOptions:launchOptions]
  }

对于Facebook SDK v4.5 +，请尝试以下方法：

目标-C

FBSDKShareLinkContent *content = [[FBSDKShareLinkContent alloc] init];
content.contentURL = [NSURL URLWithString:@"http://developers.facebook.com"];
[FBSDKShareDialog showFromViewController:self withContent:content delegate:self];

夫特

let content = FBSDKShareLinkContent()
content.contentURL = URL(string: "http://developers.facebook.com")
FBSDKShareDialog.show(from: self, with: content, delegate: self)
