facebook上的视频分享

Question

我想用sdk在脸书墙上分享图片和视频。

我使用下面的代码来分享图片

FBSDKSharePhoto *photo = [[FBSDKSharePhoto alloc] init];
photo.image = [UIImage imageNamed:@"Classic-Guitar.jpg"];
photo.userGenerated = YES;
FBSDKSharePhotoContent *content = [[FBSDKSharePhotoContent alloc] init];

content.photos = @photo；

FBSDKShareDialog *shareCodeDialog;
shareCodeDialog = [FBSDKShareDialog new];
[shareCodeDialog setDelegate:self];
[shareCodeDialog setShareContent:content];
[shareCodeDialog setFromViewController:self];
[shareCodeDialog show];

使用此代码，我可以在墙上发布图像，但在发送视频时，我使用以下代码

NSURL *videoURL = [[NSURL URLWithString:@"https://www.youtube.com/watch?v=rSAiSTkVMfs"] absoluteURL];
FBSDKShareVideo *video = [[FBSDKShareVideo alloc] init];
video.videoURL = videoURL;
FBSDKShareVideoContent *content = [[FBSDKShareVideoContent alloc] init];
content.video = video;


FBSDKShareDialog *shareCodeDialog;
shareCodeDialog = [FBSDKShareDialog new];
[shareCodeDialog setDelegate:self];
[shareCodeDialog setShareContent:content];
[shareCodeDialog setFromViewController:self];
[shareCodeDialog show];

但是它没有被发布，在委托中给出了一个错误，说error Domain=com.facebook.sdk.share Code=2 "The operation Domain=com.facebook.sdk.share Code=2. (com.facebook.sdk.share Error 2.)“videoURL的{com.facebook.sdk:FBSDKErrorArgumentValueKey=https://www.youtube.com/watch?v=rSAiSTkVMfs，com.facebook.sdk:FBSDKErrorArgumentNameKey=videoURL，com.facebook.sdk:FBSDKErrorDeveloperMessageKey=Invalid值: UserInfo=0x16d95990 }

Answer 1

videoURL属性必须是资产URL (从UIImagePickerController获取)，而不是本地文件URL/web (请参阅https://developers.facebook.com/docs/sharing/ios#videos)

如果你想分享YouTube视频(或网站上提供的任何视频)，请改用FBSDKShareLinkContent (参见https://developers.facebook.com/docs/sharing/ios#links)
