需求

iOS 9.0+

安装

CocoaPods

将以下行添加到您的 Podfile

pod 'ExpandableButton'

在您的 Podfile 中添加 use_frameworks!
运行 pod install

import ExpandableButton

使用方法

您可以使用 frame（默认为 .zero）、direction（默认为 .right）和项目（每个项目都是按钮）初始化 ExpandableButton。direction 是打开方向。items 是包含有关将来按钮信息的 [ExpandableButtonItem]。方向示例

let rightButton = ExpandableButtonView(frame: frame, direction: .right, items: items)
let leftButton = ExpandableButtonView(frame: frame, direction: .left, items: items)
let upButton = ExpandableButtonView(frame: frame, direction: .up, items: items)
let downButton = ExpandableButtonView(frame: frame, direction: .down, items: items)

带有 image 和 action 的项目

// create items with images and actions
let items = [
    ExpandableButtonItem(
        image: UIImage(named: "delete"), 
        action: {_ in
            print("delete")
        }
    ),
    ExpandableButtonItem(
        image: UIImage(named: "edit"),
        action: {_ in
            print("edit")
        }
    ),
    ExpandableButtonItem(
        image: UIImage(named: "share"), 
        action: { _ in
           print("share")
        }
    )
]
             
// create ExpandableButton
let buttonView = ExpandableButtonView(items: items)
buttonView.frame = CGRect(x: 0, y: 0, width: 60, height: 60)
buttonView.backgroundColor = .white
view.addSubview(buttonView)

带有 image、highlightedImage 和 imageEdgeInsets

let insets = UIEdgeInsets(top: 16, left: 16, bottom: 16, right: 16)
        
// create items with image, highlighted image, image insets.        
let items = [
    ExpandableButtonItem(
        image: UIImage(named: "delete"),
        highlightedImage: UIImage(named: "highlightedDelete"),
        imageEdgeInsets: insets,
        action: {_ in
            print("delete")
        }
    )
    ...
]

和 arrowWidth、separatorWidth 以及 cornerRadius

buttonView.arrowWidth = 2
buttonView.separatorWidth = 2
buttonView.layer.cornerRadius = 30

自定义 open 和 close 动作的图标，closeOpenImagesInsets

// custom open and close images
buttonView.openImage = UIImage(named: "open")
buttonView.closeImage = UIImage(named: "close")
buttonView.closeOpenImagesInsets = insets

支持 attributedTitle，highlightedAttributedTitle 和自定义项 size

// with attributed string, highlighted attributed string, custom size.
let items = [
    ExpandableButtonItem(
        attributedTitle: NSAttributedString(
            string: "Attributed Text",
            attributes: [.foregroundColor: UIColor.red]
        ),
        highlightedAttributedTitle: NSAttributedString(
            string: "Attributed Text",
            attributes: [.foregroundColor: UIColor.green]
        ),
        size: CGSize(width: 160, height: 60)
    )
]

将 attributedTitle 放置于 image 下方（使用 contentEdgeInsets、titleEdgeInsets、imageEdgeInsets、titleAlignment、imageContentMode、size）

let attributedTitle =  NSAttributedString(
    string: "Share",
    attributes: [.foregroundColor: UIColor.black,
                 .font: UIFont.systemFont(ofSize: 12)]
)

let highlightedAttributedTitle =  NSAttributedString(
    string: "Share",
    attributes: [.foregroundColor: UIColor.lightGray,
                 .font: UIFont.systemFont(ofSize: 12)]
)

let items = [
    ExpandableButtonItem(
        image: UIImage(named: "share"),
        highlightedImage: UIImage(named: "haglightedShare"),
        attributedTitle: attributedTitle,
        highlightedAttributedTitle: highlightedAttributedTitle,
        contentEdgeInsets: UIEdgeInsets(top: 6, left: 6, bottom: 6, right: 6),
        titleEdgeInsets: UIEdgeInsets(top: 24, left: -200, bottom: 0, right: 0),
        imageEdgeInsets: UIEdgeInsets(top: 6, left: 0, bottom: 24, right: 0),
        size: CGSize(width: 80, height: 60),
        titleAlignment: .center,
        imageContentMode: .scaleAspectFit
    )
]

您可以调用 open() 和 close()

let buttonView = ExpandableButtonView(items: items)

buttonView.open() 
buttonView.close()

所有选项
