Ios 使用MIBadgeButton Swift向UIButtonitem添加徽章

我正试图在我的UIBarbuttoneim中添加一个徽章，为此我在github中找到了一个：

但我不知道如何使用它

这是我定制UIBarButtonItem的代码：

let shopingCartBTN = UIButton(type: UIButtonType.Custom)
shopingCartBTN.setImage(UIImage(named: "shopingCarBarIcon"), forState: UIControlState.Normal)
shopingCartBTN.imageView?.image = UIImage(named: "shopingCarBarIcon")
shopingCartBTN.frame = CGRectMake(0, 0, 60, 30)//Just increase the width of button
shopingCartBTN.setTitle("5", forState: .Normal)
shopingCartBTN.addTarget(self, action: "", forControlEvents: UIControlEvents.TouchUpInside)
let customBarItem = UIBarButtonItem(customView: shopingCartBTN)
self.navigationItem.leftBarButtonItem = customBarItem;

我如何使用MIBadgeButton Swift为我的UIBarButtonItem制作徽章？

试试这个

//Property
    var cartBarbuttonItem:MIBadgeButton?

self.cartBarbuttonItem = MIBadgeButton(frame: CGRectMake(40, 5, 40, 44))
self.cartBarbuttonItem?.initWithFrame(frame: CGRectMake(40, 5, 40, 44), withBadgeString: "0", withBadgeInsets:  UIEdgeInsetsMake(15, 2, 0, 15))
self.cartBarbuttonItem?.setImage(UIImage(named: "test"), forState: .Normal)
self.cartBarbuttonItem?.setImage(UIImage(named: "test"), forState: .Selected)
self.cartBarbuttonItem?.addTarget(self, action: Selector("loadCart"), forControlEvents: UIControlEvents.TouchUpInside)

self.navigationItem.setLeftBarButtonItem = self.cartBarbuttonItem

您也可以使用

我刚刚编辑了答案。如果您有任何疑问，请告诉我

@IBOutlet var btnRightBadge: MIBadgeButton!

override func viewDidLoad() {
    super.viewDidLoad()

    //Custom
    let badgeButton : MIBadgeButton = MIBadgeButton(frame: CGRectMake(0, 0, 40, 40))
    badgeButton.setTitle("T1", forState: UIControlState.Normal)
    badgeButton.setTitleColor(UIColor.blackColor(), forState: UIControlState.Normal)
    badgeButton.badgeString = "1";
    let barButton : UIBarButtonItem = UIBarButtonItem(customView: badgeButton)
    self.navigationItem.leftBarButtonItem = barButton

    //From Storyboard
    btnRightBadge.badgeString = "5"
}
