This is how my Tabbar is looking right now.

如何移动徽章，使其与响铃图标的右上角重叠？

How do I move that badge so that it overlaps the top right of the bell icon? Any help is appreciated.

推荐答案

请尝试以下操作：

func repositionBadge(tabIndex: Int){

    for badgeView in self.tabBarController!.tabBar.subviews[tabIndex].subviews {

        if NSStringFromClass(badgeView.classForCoder) == "_UIBadgeView" {
            badgeView.layer.transform = CATransform3DIdentity
            badgeView.layer.transform = CATransform3DMakeTranslation(-17.0, 1.0, 1.0)
        }
    }
}

请注意，tabIndex从1开始

pay attention, tabIndex starts from 1
