NFC读者写入器 1.1.4

NFC读者写入器

Version Carthage Compatible License Platform Swift

描述

NFC读者写入器支持通过iOS设备读取NFC芯片中的数据（iOS 11）、向NFC芯片写入数据（iOS 13）以及读取NFC标签信息（iOS 13）。适用于Swift和Objective-C。

安装

CocoaPods

pod 'NFCReaderWriter'

Carthage

github "janlionly/NFCReaderWriter"

Swift 包管理器

.package(url: "https://github.com/janlionly/NFCReaderWriter.git", .upToNextMajor(from: "1.1.3")),

用法

  1. 将你的配置文件设置为支持 近距离通信标签读取;

  2. 打开你的项目目标，在 签名 & 能力 选项卡中，添加 近距离通信标签读取 能力；

  3. 请记住在你的 Info.plist 中添加 NFCReaderUsageDescription 键进行描述。

  4. 支持读取标签标识符（iOS 13），你应该将你的 NFC 标签类型描述添加到你的 Info.plist 中。

    （例如：com.apple.developer.nfc.readersession.felica.systemcodes，com.apple.developer.nfc.readersession.iso7816.select-identifiers）

更多信息请运行上面的示例。
