添加角标的UIView扩展

UIViewBadge

In many situatio, we need add a "red point" or "number with red background color" as a badge in an icon, to tell user---hey, there's something new here....
UIViewBadge is to solve this problem. It's an UIView extension in Swift, if you can find a UIView, you can easily add a badge to it. UIViewBadge only supported on iOS > 8 because Swift only support uses dynamic frameworks. As a result, if you want to support iOS < 8, download the code and copy the file to your project.

Example thunmbnail:

Install

pod 'UIViewBadge'

Usage In Swift

```swift```` //red point/number in UIButton aButton.setBadgeHidden(false) aButton.setBadgeStyle(BadgeStyle.Point(CGSizeMake(10, 10))) aButton.setBadgeBackgroundColor(UIColor.purpleColor())

    //red point/number in UIView
    aView.setBadgeHidden(false)
    aView.setBadgeBackgroundColor(UIColor.redColor())
    aView.setBadgeFontColor(UIFont.systemFontOfSize(10))
    aView.setBadgeStyle(BadgeStyle.Number(90000))
    
    //red point/number in UITabBar
    //    self.tabBarItem.badgeValue = "2";
    let view = self.tabBarController?.tabBar.viewInTabbarAtIndex(0)
    view?.backgroundColor = UIColor.yellowColor()
    view?.setBadgeHidden(false)
    view?.setBadgeStyle(BadgeStyle.Point(CGSizeMake(12, 12)))
    view?.setBadgeBackgroundColor(UIColor.purpleColor())
