20 | 21 | - [Requirements](#requirements) 22 | - [Installation](#installation) 23 | - [Usage](#usage) 24 | 25 | 26 | ## Requirements 27 | 28 | - Swift 4.2 29 | - iOS 9.0.0+ 30 | - Xcode 9.x 31 | 32 |
33 | 34 | ## Installation 35 | 36 | ### Carthage 37 | 38 | [Carthage](https://github.com/Carthage/Carthage) is a decentralized dependency manager that builds your dependencies and provides you with binary frameworks. 39 | 40 | To integrate **SwiftScan** into your Xcode project using Carthage, specify it in your `Cartfile`: 41 | 42 | ```ogdl 43 | github "chenjie1219/SwiftScan" 44 | ``` 45 | 46 | Run `carthage update` to build the framework and drag the built `SwiftScanner.framework` into your Xcode project. 47 | 48 | ### Manually 49 | 50 | Just download the project, and drag and drop the "SwiftScanner" folder in your project. 51 | 52 |
53 | 54 | ## Usage 55 | 56 | #### 1、在 info.plist 中添加以下字段（iOS 10 之后需添加的字段） 57 | 58 | * `NSCameraUsageDescription (相机权限访问)`
