Question

我刚开始学习swift。
我安装了Cocoapod并试图看看我是否可以实施。

我真的不知道如何解决这个问题，其余的代码将在下面提供。

override func viewDidLoad() {
super.viewDidLoad()



let menuItemImage = UIImage(named: "bg-menuitem")!
let menuItemHighlitedImage = UIImage(named: "bg-menuitem-highlighted")!

let starImage = UIImage(named: "icon-star")!

let starMenuItem1 = PathMenuItem(image: menuItemImage, highlightedImage: menuItemHighlitedImage, contentImage: starImage)

let starMenuItem2 = PathMenuItem(image: menuItemImage, highlightedImage: menuItemHighlitedImage, contentImage: starImage)

let starMenuItem3 = PathMenuItem(image: menuItemImage, highlightedImage: menuItemHighlitedImage, contentImage: starImage)

let starMenuItem4 = PathMenuItem(image: menuItemImage, highlightedImage: menuItemHighlitedImage, contentImage: starImage)

let starMenuItem5 = PathMenuItem(image: menuItemImage, highlightedImage: menuItemHighlitedImage, contentImage: starImage)

let items = [starMenuItem1, starMenuItem2, starMenuItem3, starMenuItem4, starMenuItem5]

let startItem = PathMenuItem(image: UIImage(named: "bg-addbutton")!,
    highlightedImage: UIImage(named: "bg-addbutton-highlighted"),
    contentImage: UIImage(named: "icon-plus"),
    highlightedContentImage: UIImage(named: "icon-plus-highlighted"))

let menu = PathMenu(frame: view.bounds, startItem: startItem, items: items)

menu.delegate = self

menu.startPoint = CGPointMake(UIScreen.mainScreen().bounds.width/2, self.view.frame.size.height - 30.0)
menu.menuWholeAngle = CGFloat(M_PI) - CGFloat(M_PI/5)
menu.rotateAngle = -CGFloat(M_PI_2) + CGFloat(M_PI/5) * 1/2
menu.timeOffset = 0.0
menu.farRadius = 110.0
menu.nearRadius = 90.0
menu.endRadius = 100.0
menu.animationDuration = 0.5

// Do any additional setup after loading the view, typically from a nib.
  }

   override func didReceiveMemoryWarning() {
super.didReceiveMemoryWarning()
// Dispose of any resources that can be recreated.
 }


}

委托协议（PathMenuDelegate） _如何将下面显示的其余代码实现到viewDidLoad

中

 func pathMenu(menu: PathMenu, didSelectIndex idx: Int)
 func pathMenuDidFinishAnimationClose(menu: PathMenu)
 func pathMenuDidFinishAnimationOpen(menu: PathMenu)
 func pathMenuWillAnimateOpen(menu: PathMenu)
 func pathMenuWillAnimateClose(menu: PathMenu)

Answer 1

　　　　
class ViewController: UIViewController{
    override func viewDidLoad() {
        super.viewDidLoad()
       ~~~
        menu.delegate = self
        self.view.addSubview(menu)
    }
}
extension ViewController: PathMenuDelegate {
    func didSelect(on menu: PathMenu, index: Int) {
        print("Select the index : \(index)")
    }
    func willStartAnimationOpen(on menu: PathMenu) {
        print("Menu will open!")
    }

    func willStartAnimationClose(on menu: PathMenu) {
        print("Menu will close!")
    }

    func didFinishAnimationOpen(on menu: PathMenu) {
        print("Menu was open!")
    }

    func didFinishAnimationClose(on menu: PathMenu) {
        print("Menu was closed!")
    }
}

Answer 2

您无法将这些代码放入viewDidLoad。

使相应的viewController符合PathMenuDelegate

然后开始输入协议功能，您将获得有关＆＃39;

的建议

Answer 3

您提出质疑的所有内容，请在此处查看作者的示例代码：非常简单直接。这些委托的功能仅用于处理来自lib的事件。这里的示例只是打印一些东西向您展示，＆＃34;您的代码可以正常工作＆＃34;。

类型“viewController”不符合协议“PathMenuDelegate”
