使用 MIBadgeButton-Swift 向 UIButtonitem 添加徽章

Question

我正在尝试向我的 UIBarButtonItem 添加一个徽章，为此我找到了这个 github :

但是我不知道怎么用

这是我的代码，它使我的自定义 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 为我的 UIBarButtonItem 制作徽章？

Answer 1

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

Answer 2

这是自定义视图和情节提要中的两个示例

通过设置自定义从故事板 class :

代码

@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"
}
