facebook - 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

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

尽管我没有排除“UIActivityTypePostToFacebook”，但我看不到“在 Facebook 上分享”图标。facebook 没有预定义的 UIActivity 吗？

谢谢

Answer 1

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要排除的任何其他类型的活动类型
