Assign your Caption String to caption Key value

将您的标题字符串分配给标题键值

@property (nonatomic, copy) NSString *caption;

@property (nonatomic, copy) NSString *caption;

Try This :

尝试这个 ：

 FBSDKSharePhoto *photo = [[FBSDKSharePhoto alloc] init];
      photo.image = image;
      photo.userGenerated = YES;
    photo.caption = @"Add Your caption";
      FBSDKSharePhotoContent *content = [[FBSDKSharePhotoContent alloc] init];
      content.photos = @[photo];
    [FBSDKShareDialog showFromViewController:self
                                 withContent:content
                                    delegate:nil];

As @NANNAV posted it will work, but if you want to share silently with out any FB Dialog screen then use "shareWithContent" as below, but you need to submit your Facebook app for review.

正如@NANNAV 发布的那样，它会起作用，但如果您想在没有任何 FB 对话框屏幕的情况下静默分享，请使用如下所示的“shareWithContent”，但您需要提交您的 Facebook 应用程序以供审核。

Code in Obj-c

Obj-c 中的代码

FBSDKSharePhoto *sharePhoto = [[FBSDKSharePhoto alloc] init];
sharePhoto.caption = @"Test Caption";
sharePhoto.image = [UIImage imageNamed:@"BGI.jpg"];

FBSDKSharePhotoContent *content = [[FBSDKSharePhotoContent alloc] init];
content.photos = @[sharePhoto];

[FBSDKShareAPI shareWithContent:content delegate:self];

Code in Swift

Swift 中的代码

var sharePhoto = FBSDKSharePhoto()
sharePhoto.caption = "Test"
sharePhoto.image = UIImage(named: "BGI.jpg")

var content = FBSDKSharePhotoContent()
content.photos = [sharePhoto]

FBSDKShareAPI.shareWithContent(content, delegate: self)
