FBSDKSharingDelegate回调无法正常工作.我可以使用ios SDK发布到Facebook,但我想检测帖子是否成功,并采取其他措施通知用户.但是,回调对我不起作用.委托方法没有被调用,我不知道为什么.
使用ios8,Parse作为我的后端.在Parse中,用户链接到FB.我正在使用IOS模拟器.
我尝试过的：
我已确保授予,保存并链接到Parse用户的发布权限.我运行检查并检测到“publish_actions”.发布工作正常,因为我可以看到Facebook帐户上的帖子.这只是回调无法正常工作.我检查了我的fb设置,它看起来很好.为了最好的衡量标准,我已经包含了我的应用代表的相关代码.我用XXXX阻止了机密密钥.
码：
1st：查看用户是否登录Parse,如果没有,请发送登录并链接到Facebook帐户.完成后,我请求“发布”权限并将该附加权限链接到Parse用户.我知道这可以在我重新编译时使用b / c,它会记住“发布”权限并直接进入帖子.

if(error){
NSLog(@"There was an issue linking your facebook account. Please try again.");
}
else {
NSLog(@"facebook account is linked");
//Send the facebook status update
[self shareSegmentWithFacebookComposer];
}
}];
}
-(void)shareSegmentWithFacebookComposer{
if ([[FBSDKAccessToken currentAccessToken] hasGranted:@"publish_actions"]) {
[self publishFBPost]; //publish
} else {
NSLog(@"no publish permissions"); // no publish permissions so get them, then post
[PFFacebookUtils linkUserInBackground:[PFUser currentUser]
withPublishPermissions:@[ @"publish_actions"]
block:^(BOOL succeeded, NSError *error) {
if (succeeded) {
NSLog(@"User now has read and publish permissions!");
[self publishFBPost];
}
}];
这是帖子的制作地点：
-(void) publishFBPost{
FBSDKShareLinkContent *content = [FBSDKShareLinkContent new];
content.contentURL = [NSURL URLWithString:[self.selectedSegment valueForKey:@"linkToContent"]];
content.contentTitle = [self.selectedProgram valueForKey:@"programTitle"];
content.contentDescription = [self.selectedSegment valueForKey:@"purposeSummary"];
PFFile *theImage = [self.selectedSegment valueForKey:@"segmentImage"];
NSString *urlString = theImage.url;
NSURL *url = [NSURL URLWithString:urlString];
content.imageURL = url;
FBSDKShareDialog *shareDialog = [FBSDKShareDialog new];
[shareDialog setMode:FBSDKShareDialogModeAutomatic];
// [FBSDKShareDialog showFromViewController:self.messageTableViewController withContent:content delegate:self];
[shareDialog setShareContent:content];
[shareDialog setDelegate:self];
[shareDialog setFromViewController:self.messageTableViewController];
[shareDialog show];
}
以下代表方法无效.在帖子完成后的含义,我可以在FB帐户上看到它,但这些委托方法都不会执行.
#pragma mark - delegate methods
- (void)sharer:(id<FBSDKSharing>)sharer didCompleteWithResults:(NSDictionary *)results {
// if ([sharer isEqual:self.shareDialog]) {
NSLog(@"I'm going to go crazy if this doesn't work.%@",results);
// Your delegate code
// }
}
- (void)sharer:(id<FBSDKSharing>)sharer didFailWithError:(NSError *)error
{
NSLog(@"sharing error:%@", error);
NSString *message = error.userInfo[FBSDKErrorLocalizedDescriptionKey] ?:
@"There was a problem sharing, please try again later.";
NSString *title = error.userInfo[FBSDKErrorLocalizedTitleKey] ?: @"Oops!";
[[[UIAlertView alloc] initWithTitle:title message:message delegate:nil cancelButtonTitle:@"OK" otherButtonTitles:nil] show];
}
- (void)sharerDidCancel:(id<FBSDKSharing>)sharer
{
NSLog(@"share cancelled");
}
控制台输出：
发布后我收到的唯一消息是几秒后出现此消息：
plugin com.apple.share.Facebook.post invalidated
请帮忙！

最佳答案 我想我回答这个问题太迟了,但是其他人也可能陷入这个问题,这就是为什么要分享我的知识.
As per Facebook API documentation
sharer:didCompleteWithResults: Sent to the delegate when the share completes without error or cancellation.
The results from the sharer. This may be nil or empty.
它可能是因为只有在成功共享帖子时才会调用此委托方法.如果失败,另一个委托方法sharer：didFailWithError：get.我认为Facebook API不需要添加结果参数就是这种情况.
因此,根据我的经验,如果调用sharer：didCompleteWithResults,那么这意味着成功.
