本文将演示使用JTAppleCalendar制作美观的日历。
首先确保在项目中已经安装了所需的第三方库。
点击【Podfile】,查看安装配置文件。
1 platform :ios, '12.0' 2 use_frameworks! 3 4 target 'DemoApp' do 5 source 'https://github.com/CocoaPods/Specs.git' 6 pod 'JTAppleCalendar', '~> 6.0' 7 end
根据配置文件中的相关配置，安装第三方库
然后点击打开【DemoApp.xcworkspace】项目文件。
在项目文件夹【DemoApp】上鼠标右键，弹出右键菜单：
【New File】->【Cocoa Touch Class】->【Next】->
【Class】：CellView ,类名。
【Subclass of】：JTAppleCalendar ，父类
【Language】：Swift
->【Next】->【Create】
在项目导航区，打开刚刚创建的代码文件【CellView.swift】
1 //引入第三方类库 2 import JTAppleCalendar 3 4 class CellView: JTAppleDayCellView { 5 6 @IBOutlet var dayLabel: UILabel! 7 8 @IBOutlet var selectedView: UIView! 9 }
在项目文件夹【DemoApp】上鼠标右键，弹出右键菜单：
【New File】->【View】视图->【Next】->【Save As】：CellView ->【Create】
点击【CellView.xib】，设置相关属性
