Summary

顾名思义，一个会散开的按钮，主体按钮被点击后触发子按钮的展出，选择其中一个功能子按钮，或者点击任意地方，触发子按钮的收缩隐藏。

A Button spread its sub path buttons like the flower or sickle(two spread mode) if you click it, once again, close.And you can also change the SpreadPositionMode between FixedMode & TouchBorderMode， while one like the marbleBall fixed on the wall, another one like the AssistiveTouch is iphone。

两种展开模式(SpreadMode)：镰刀模式 & 花朵模式

SpreadButton，大家根据他的功能帮起个中文名吧两种位置模式(SpreadPositionMode)：锁定模式 & 粘连边缘模式，在粘连边缘模式下，根据主体按钮的位置，会实时更新展开模式

let your project include SpreadButton.swift & SpreadSubButton.swiftoc项目需要在bridge头文件里import他们

Usage

以swift为例子：1.通过SpreadButton的构造方法来创建一个SpreadButton对象，传入主体按钮的背景图片，高亮图片(非必须)，还有位置，如果传入的UIImage为nil，放心，编译时就会报错

let spreadButton = SpreadButton(image: UIImage(named: "powerButton"),                          highlightImage: UIImage(named: "powerButton_highlight"),                              position: CGPointMake(40, UIScreen.mainScreen().bounds.height - 40))

2.创建子按钮(SpreadSubButton)，传入背景图片，高亮图片(非必须)，还有一个尾随闭包，子按钮被点击后我们这个闭包会被调用，同样的，如果传入的UIImage为nil，编译时会报错

let btn1 = SpreadSubButton(backgroundImage: UIImage(named: "clock"),                               highlightImage: UIImage(named: "clock_highlight")) { (index, sender) -> Void in      print("first button be clicked!!!") }  let btn2 = SpreadSubButton(backgroundImage: UIImage(named: "pencil"),                               highlightImage: UIImage(named: "pencil_highlight")) { (index, sender) -> Void in      print("second button be clicked!!!") } //像这样你可以创建更多

3.通过-setSubButtons为SpreadButton设置子按钮，这里你可以传入nil或者SpreadButton?试试，没关系，里面做了保险，会排除，哈哈扯远了，用到的知识可以看看我的这篇文章

spreadButton?.setSubButtons([btn1, btn2, btn3, btn4, btn5])

4.根据你的需求，去定制这个SpreadButton，具体可以选什么参数，看看上面的Custom-made

spreadButton?.mode = SpreadMode.SpreadModeSickleSpread   spreadButton?.direction = SpreadDirection.SpreadDirectionRightUp   spreadButton?.positionMode = SpreadPositionMode.SpreadPositionModeFixed  /*  and you can assign a newValue to change the default spreadButton?.animationDuring = 0.2   spreadButton?.animationDuringClose = 0.25   spreadButton?.radius = 180   spreadButton?.coverAlpha = 0.3   spreadButton?.coverColor = UIColor.yellowColor()   spreadButton?.touchBorderMargin = 10.0   */

5.每种动作的前后，都有对应的Block供使用，像这样给他们赋值:

spreadButton?.buttonWillSpreadBlock = { print(CGRectGetMaxY($0.frame)) }   spreadButton?.buttonDidSpreadBlock = { _ in print("did spread") }   spreadButton?.buttonWillCloseBlock = { _ in print("will closed") }   spreadButton?.buttonDidCloseBlock = { _ in print("did closed") }

6.最后加到你的view里面，ok，可以开始玩耍

if spreadButton != nil {       self.view.addSubview(spreadButton!) }
