我试图在我的UIBarButtonItem中添加一个徽章，为此我找到了一个github：
但是我不知道怎么用
这是我的代码，使我可以自定义UIBarButtonItem：
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;
如何使用MIBadgeButton-Swift为UIBarButtonItem制作徽章？
尝试一次。
//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
