---0.1.5更新粘连边缘模式(home键模式)---

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




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

Property:

  • animationDuring: assign the ‘animationDuring’ can also change ‘animationDuringSpread’ & ‘animationDuringClose’,default is 0.2

Installation

Cocoapods

pod 'SpreadButton'

Fork form my github

let your project include SpreadButton.swift & SpreadSubButton.swift
oc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!)
}
