76 | 77 | target '' do 78 | pod 'Tiercel' 79 | end 80 | ``` 81 | 82 | 最后运行命令 83 | 84 | ```bash 85 | $ pod install 86 | ``` 87 | 88 | ### Swift Package Manager 89 | 90 | 从 Xcode 11 开始，集成了 Swift Package Manager，使用起来非常方便。Tiercel 也支持通过 Swift Package Manager 集成。 91 | 92 | 在 Xcode 的菜单栏中选择 `File > Swift Packages > Add Pacakage Dependency`，然后在搜索栏输入 93 | 94 | `git@github.com:Danie1s/Tiercel.git`，即可完成集成 95 | 96 | ### 手动集成 97 | 98 | Tiercel 也支持手动集成，只需把本项目文件夹中的`Tiercel`文件夹拖进需要集成的项目即可 99 | 100 | 101 | 102 | ## Demo 103 | 104 | 打开本项目文件夹中 `Tiercel.xcodeproj` ，可以直接运行 Demo 105 | 106 | 107 | 108 | 109 | 110 | ## 用法 111 | 112 | ### 基本用法 113 | 114 | 一行代码开启下载 115 | 116 | ```swift 117 | // 创建下载任务并且开启下载，同时返回可选类型的DownloadTask实例，如果url无效，则返回nil 118 | let task = sessionManager.download("http://dldir1.qq.com/qqfile/QQforMac/QQ_V4.2.4.dmg") 119 | 120 | // 批量创建下载任务并且开启下载，返回有效url对应的任务数组，urls需要跟fileNames一一对应 121 | let tasks = sessionManager.multiDownload(URLStrings) 122 | ``` 123 | 124 | 可以对任务设置状态回调 125 | 126 | ```swift 127 | let task = sessionManager.download("http://dldir1.qq.com/qqfile/QQforMac/QQ_V4.2.4.dmg") 128 | 129 | task?.progress(onMainQueue: true) { (task) in 130 | let progress = task.progress.fractionCompleted 131 | print("下载中, 进度：\(progress)") 132 | }.success { (task) in 133 | print("下载完成") 134 | }.failure { (task) in 135 | print("下载失败") 136 | } 137 | ``` 138 | 139 | 可以通过 URL 对下载任务进行操作，也可以直接操作下载任务 140 | 141 | ```swift 142 | let URLString = "http://dldir1.qq.com/qqfile/QQforMac/QQ_V4.2.4.dmg" 143 | 144 | // 通过 URL 对下载任务进行操作 145 | sessionManager.start(URLString) 146 | sessionManager.suspend(URLString) 147 | sessionManager.cancel(URLString) 148 | sessionManager.remove(URLString, completely: false) 149 | 150 | // 直接对下载任务进行操作 151 | sessionManager.start(task) 152 | sessionManager.suspend(task) 153 | sessionManager.cancel(task) 154 | sessionManager.remove(task, completely: false) 155 | ``` 156 | 157 | 158 | 159 | ### 后台下载 160 | 161 | 从 Tiercel 2.0 开始支持原生的后台下载，只要使用 Tiercel 开启了下载任务： 162 | 163 | - 手动 Kill App，任务会暂停，重启 App 后可以恢复进度，继续下载 164 | - 只要不是手动 Kill App，任务都会一直在下载，例如： 165 | - App 退回后台 166 | - App 崩溃或者被系统关闭 167 | - 重启手机 168 | 169 | 如果想了解后台下载的细节和注意事项，可以查看：[iOS 原生级别后台下载详解](https://github.com/Danie1s/Tiercel/wiki/iOS-%E5%8E%9F%E7%94%9F%E7%BA%A7%E5%88%AB%E5%90%8E%E5%8F%B0%E4%B8%8B%E8%BD%BD%E8%AF%A6%E8%A7%A3) 170 | 171 | 172 | 173 | ### 文件校验 174 | 175 | Tiercel 提供了文件校验功能，可以根据需要添加，校验结果在回调的`task.validation`里 176 | 177 | ```swift 178 | 179 | let task = sessionManager.download("http://dldir1.qq.com/qqfile/QQforMac/QQ_V4.2.4.dmg") 180 | // 回调闭包可以选择是否在主线程上执行 181 | task?.validateFile(code: "9e2a3650530b563da297c9246acaad5c", 182 | type: .md5, 183 | onMainQueue: true) 184 | { (task) in 185 | if task.validation == .correct { 186 | // 文件正确 187 | } else { 188 | // 文件错误 189 | } 190 | } 191 | ``` 192 | 193 | 194 | 195 | ### 更多 196 | 197 | 有关 Tiercel 3.0 的详细使用方法和升级迁移，请查看 [Wiki](https://github.com/Danie1s/Tiercel/wiki) 198 | 199 | 200 | 201 | 202 | ## License 203 | 204 | Tiercel is available under the MIT license.
