time ext cells star 過去 tco 處理 github 安裝第三方
本文將演示使用JTAppleCalendar制作美觀的日歷。
首先確保在項目中已經安裝了所需的第三方庫。
點擊【Podfile】,查看安裝配置文件。
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
根據配置文件中的相關配置，安裝第三方庫
然後點擊打開【DemoApp.xcworkspace】項目文件。
在項目文件夾【DemoApp】上鼠標右鍵，彈出右鍵菜單：
【New File】->【Cocoa Touch Class】->【Next】->
【Class】：CellView ,類名。
【Subclass of】：JTAppleCalendar ，父類
【Language】：Swift
->【Next】->【Create】
在項目導航區，打開剛剛創建的代碼文件【CellView.swift】
1 //引入第三方類庫 2 import JTAppleCalendar 3 4 class CellView: JTAppleDayCellView {5 6 @IBOutlet var dayLabel: UILabel! 7 8 @IBOutlet var selectedView: UIView! 9 }
在項目文件夾【DemoApp】上鼠標右鍵，彈出右鍵菜單：
【New File】->【View】視圖->【Next】->【Save As】：CellView ->【Create】
點擊【CellView.xib】，設置相關屬性

在項目導航區，打開視圖控制器的代碼文件【ViewController.swift】
