Swift - 获取应用名称、应用版本、设备型号、系统版本等信息

有时我们在 App 中提交一些统计信息或者用户反馈信息时，为了能更好地进行分析，通常会附带上当前应用程序的名称、版本号、设备型号、以及设备系统版本。下面演示如何获取这些信息。

1，效果图

程序启动后自动获取相关的应用信息以及设备信息，并打印到控制台中。

2，样例代码

默认情况下我从 UIDevice 中获取设备型号时只能得到 iPhone、iPod Touch 这样笼统的类型数据。

这里对 UIDevice 做个扩展，使其可以得到具体的设备型号，比如：iPhone 6s Plus 这样准确的设备款式。

import UIKit

class ViewController: UIViewController {

override func viewDidLoad() {

super.viewDidLoad()

//应用程序信息

let infoDictionary = Bundle.main.infoDictionary!

let appDisplayName = infoDictionary["CFBundleDisplayName"] //程序名称

let majorVersion = infoDictionary["CFBundleShortVersionString"]//主程序版本号

let minorVersion = infoDictionary["CFBundleVersion"]//版本号（内部标示）

let appVersion = majorVersion as! String

//设备信息

let iosVersion = UIDevice.current.systemVersion //iOS版本

let identifierNumber = UIDevice.current.identifierForVendor //设备udid

let systemName = UIDevice.current.systemName //设备名称

let model = UIDevice.current.model //设备型号

let modelName = UIDevice.current.modelName //设备具体型号

let localizedModel = UIDevice.current.localizedModel //设备区域化型号如A1533

//打印信息

print("程序名称：\(appDisplayName)")

print("主程序版本号：\(appVersion)")

print("内部版本号：\(minorVersion)")

print("iOS版本：\(iosVersion)")

print("设备udid：\(identifierNumber)")

print("设备名称：\(systemName)")

print("设备型号：\(model)")

print("设备具体型号：\(modelName)")

print("设备区域化型号：\(localizedModel)")

}

override func didReceiveMemoryWarning() {

super.didReceiveMemoryWarning()

}

//扩展UIDevice

extension UIDevice {

//获取设备具体详细的型号

var modelName: String {

var systemInfo = utsname()

uname(&systemInfo)

let machineMirror = Mirror(reflecting: systemInfo.machine)

let identifier = machineMirror.children.reduce("") { identifier, element in

guard let value = element.value as? Int8, value != 0 else { return identifier }

return identifier + String(UnicodeScalar(UInt8(value)))

}

switch identifier {

case "iPod5,1": return "iPod Touch 5"

case "iPod7,1": return "iPod Touch 6"

case "iPhone3,1", "iPhone3,2", "iPhone3,3": return "iPhone 4"

case "iPhone4,1": return "iPhone 4s"

case "iPhone5,1", "iPhone5,2": return "iPhone 5"

case "iPhone5,3", "iPhone5,4": return "iPhone 5c"

case "iPhone8,2": return "iPhone 6s Plus"

case "iPhone9,1": return "iPhone 7 (CDMA)"

case "iPhone9,3": return "iPhone 7 (GSM)"

case "iPhone9,2": return "iPhone 7 Plus (CDMA)"

case "iPhone9,4": return "iPhone 7 Plus (GSM)"

case "iPad2,1", "iPad2,2", "iPad2,3", "iPad2,4":return "iPad 2"

case "iPad3,1", "iPad3,2", "iPad3,3": return "iPad 3"

case "iPad3,4", "iPad3,5", "iPad3,6": return "iPad 4"

case "iPad4,1", "iPad4,2", "iPad4,3": return "iPad Air"

case "iPad5,3", "iPad5,4": return "iPad Air 2"

case "iPad2,5", "iPad2,6", "iPad2,7": return "iPad Mini"

case "iPad4,4", "iPad4,5", "iPad4,6": return "iPad Mini 2"

case "iPad4,7", "iPad4,8", "iPad4,9": return "iPad Mini 3"

case "iPad5,1", "iPad5,2": return "iPad Mini 4"

case "iPad6,7", "iPad6,8": return "iPad Pro"

case "AppleTV5,3": return "Apple TV"

case "i386", "x86_64": return "Simulator"

default: return identifier
