我可以使用UIActivityViewController在Facebook上分享吗？

Question

我正在尝试使用UIActivityViewController在Facebook上分享.当我使用的时候

UIImage* image = [UIImage imageNamed:@"image1.png"];
NSArray* dataToShare = @[@"test",image];
UIActivityViewController* activityViewController =
[[UIActivityViewController alloc] initWithActivityItems:dataToShare
                                  applicationActivities:nil];
activityViewController.excludedActivityTypes = @[UIActivityTypePrint, UIActivityTypeCopyToPasteboard, UIActivityTypeAssignToContact, UIActivityTypeSaveToCameraRoll];

虽然我没有排除"UIActivityTypePostToFacebook",但我看不到"在Facebook上分享"图标.Facebook没有预定义的UIActivity吗？

谢谢

您必须登录您的iPhone设置:设置 - > Facebook

Answer 2

试试这个：如果你只想分享 Facebook 图标：

-(IBAction)shareButtonPressed:(id)sender { NSLog(@"shareButton pressed");

NSString *texttoshare = _txt;
UIImage *imagetoshare = _img;
NSArray *activityItems = @[texttoshare, imagetoshare];    
UIActivityViewController *activityVC = [[UIActivityViewController alloc] initWithActivityItems:activityItems applicationActivities:nil];
activityVC.excludedActivityTypes = @[UIActivityTypeAssignToContact, UIActivityTypePrint, UIActivityTypePostToTwitter, UIActivityTypePostToWeibo];
[self presentViewController:activityVC animated:TRUE completion:nil];
}

//在排除的活动类型列表中插入您想要排除的任何其他类型的活动类型
