swift - 如何在 UITabBarController 的 TabBar 项之间插入分隔符

Question

我正在使用以下代码在 TabBar 项之间添加分隔符 View 。它们在 iPhone 中可见，但在 iPad 中不可见。

//Add seprators Line
    if let items = self.tabBar.items {
        //Get the height of the tab bar            
        let height = self.tabBar.bounds.height
        //Calculate the size of the items
        let numItems = CGFloat(items.count)
        let itemSize = CGSize(
            width: tabBar.frame.width / numItems,
            height: tabBar.frame.height)

        for (index, _) in items.enumerated() {
            //We don't want a separator on the left of the first item.
            if index > 0 {
                //Xposition of the item
                let xPosition = itemSize.width * CGFloat(index)
                /* Create UI view at the Xposition,
                 with a width of 0.5 and height equal
                 to the tab bar height, and give the
                 view a background color
                 */
                let separator = UIView(frame: CGRect(
                    x: xPosition, y: 0, width: 0.5, height: height))
                separator.backgroundColor = UIColor.blue
                tabBar.insertSubview(separator, at: 1)
            }
        }
    }

成功了。这是我使用的:

self.tabBar.itemPositioning =  UITabBarItemPositioning.fill
