Question

我使用最新的Facebook SDK for iOS平台。我使用FBSDKShareDialog将图像分享到Facebook，代码可以共享图像到Facebook。但我想获得共享结果委托。

setTimeout(hello1, 3000);

我还在AppDelegate.m中添加了建议代码

- (void)sharedImage:(UIImage *) sharedImage
 fromViewController:(UIViewController *) fromViewController {
    FBSDKSharePhoto *photo  = [[FBSDKSharePhoto alloc] init];
    photo.image             = sharedImage;
    photo.userGenerated     = YES;

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

    FBSDKShareDialog *dialog = [[FBSDKShareDialog alloc] init];
    dialog.fromViewController = fromViewController;
    dialog.shareContent = content;
    dialog.delegate = self;
    dialog.mode = FBSDKShareDialogModeShareSheet;
    [dialog show];
}
#pragma mark - FBSDKSharingDelegate
- (void)sharer:(id<FBSDKSharing>)sharer didCompleteWithResults:(NSDictionary *)results {

}
- (void)sharer:(id<FBSDKSharing>)sharer didFailWithError:(NSError *)error {

}
- (void)sharerDidCancel:(id<FBSDKSharing>)sharer {

}

但是从未调用过FBSDKSharingDelegate方法。

您正在正确设置fromViewController但该控制器应该是委托而不是对象。下面是代码正在运行并且委托被调用

- (IBAction)facebookButtonClick:(UIButton *)sender {
    //    FacebookShare *facebookShare = [[FacebookShare alloc] init];
    //    [facebookShare sharedImage:[UIImage imageNamed:@"facebook_share"]
    //            fromViewController:self];
    FBSDKSharePhoto *photo  = [[FBSDKSharePhoto alloc] init];
    photo.image             = [UIImage imageNamed:@"facebook_share"];
    photo.userGenerated     = YES;

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

    FBSDKShareDialog *dialog = [[FBSDKShareDialog alloc] init];
    dialog.fromViewController = self;
    dialog.delegate = self;
    dialog.shareContent = content;
    dialog.mode = FBSDKShareDialogModeShareSheet;
    [dialog show];
}

//FBSDKSharingDelegate
- (void)sharer:(id<FBSDKSharing>)sharer didCompleteWithResults:(NSDictionary *)results {
    NSLog(@"completed");
}

- (void)sharer:(id<FBSDKSharing>)sharer didFailWithError:(NSError *)error {
    NSLog(@"fail %@",error.description);
}

- (void)sharerDidCancel:(id<FBSDKSharing>)sharer {
    NSLog(@"cancel");
}

在我的情况下，那是因为我的视图控制器已经解散，因此无法调用我的委托功能。所以请检查您的视图控制器被解雇的天气。希望会有所帮助。

没有调用FBSDKShareDialog委托
