UIActivity popover：如何只显示一行符号？

Question

我的应用程序应该在按下按钮时向服务器发送图片。为此，我选择使用 AirDrop，并希望 UI 尽可能简单。现在我可以排除除 AirDrop 之外的所有活动，但弹出窗口仍然看起来很乱：

如何去掉多余的两条线？它们毫无用处。

如果有帮助，这里是点击按钮时调用的方法：

- (IBAction)orderButtonTapped:(UIButton *)sender {

    UIImage *image   = [self.detailViewController.paint extractImageFromBitmap];
    UIDevice *device = UIDevice.currentDevice;
    NSArray *items   = @[device.name, image];
    UIActivityViewController *activityViewController = [[UIActivityViewController alloc] initWithActivityItems:items
                                                                                         applicationActivities:nil];
    activityViewController.excludedActivityTypes = @[UIActivityTypePostToFacebook,
                                                     UIActivityTypePostToTwitter,
                                                     UIActivityTypePostToWeibo,
                                                     UIActivityTypeMessage,
                                                     UIActivityTypeMail,
                                                     UIActivityTypePrint,
                                                     UIActivityTypeCopyToPasteboard,
                                                     UIActivityTypeAssignToContact,
                                                     UIActivityTypeSaveToCameraRoll,
                                                     UIActivityTypeAddToReadingList,
                                                     UIActivityTypePostToFlickr,
                                                     UIActivityTypePostToVimeo,
                                                     UIActivityTypePostToTencentWeibo];
    activityViewController.popoverPresentationController.sourceView = self.view;

// if iPhone
    if (UI_USER_INTERFACE_IDIOM() == UIUserInterfaceIdiomPhone) {
        [self presentViewController:activityViewController animated:YES completion:nil];
    }

// if iPad
    else {
        CGFloat xPos = self.orderButton.frame.origin.x + self.orderButton.frame.size.width/2;
        CGFloat yPos = self.orderButton.frame.origin.y;
        UIPopoverController *popup = [[UIPopoverController alloc] initWithContentViewController:activityViewController];
        [popup presentPopoverFromRect:CGRectMake(xPos, yPos, 0, 0)
                               inView:self.view
             permittedArrowDirections:UIPopoverArrowDirectionAny
                             animated:YES];
    }
}

你不能。 用户可以在那里自定义第 3 方活动。您不能只将选定的活动（例如 AirDrop）列入白名单，而只能将其中一些活动列入黑名单。这就是您已经在做的事情。
