Swift-優(yōu)雅的菜單.gif

這是一款優(yōu)雅的菜單

在cocoapods.org或者是github上都可以找的到

下面我就來說一下他的使用方法

首先在你的Podfile文件中pod這個(gè)ClircleMenu

target 'Swift-優(yōu)雅的菜單' do
use_frameworks!
pod 'CircleMenu', '~> 1.0.0'
end

然后在你的storyboard中拖拽一個(gè)按鈕，并且指定他的類，如下圖

之后設(shè)置按鈕的屬性依次為，圓角，button的數(shù)量，間距等。

最后在ViewController中import CircleMenu并且添加代理

代碼如下

        button.backgroundColor = items[atIndex].color
        button.setImage(UIImage(imageLiteral: items[atIndex].icon), forState: .Normal)
