Swift: 讀取 iOS 設備的型號/版本資料
let dictionary = Bundle.main.infoDictionary!
let app_version = dictionary["CFBundleShortVersionString"] as! String
let app_build = dictionary["CFBundleVersion"] as! String
let app_dDisplayName = dictionary["CFBundleDisplayName"]
print("app_dDisplayName = \(app_dDisplayName!)")
print("app_version = \(app_version)")
print("app_build = \(app_build)")
print("UIDevice.current.name = \(UIDevice.current.name)")
print("UIDevice.current.model = \(UIDevice.current.model)")
print("UIDevice.current.systemName = \(UIDevice.current.systemName)")
print("UIDevice.current.systemVersion = \(UIDevice.current.systemVersion)")
print("UIDevice.current.identifierForVendor! = \(UIDevice.current.identifierForVendor!)")
UIDevice.current.identifierForVendor --> 當 app重裝後 identifierForVendor 會變
模擬器 的結果：
app_dDisplayName = helloApp
app_version = 1.0
app_build = 1
UIDevice.current.name = ffmac (Macbook的名稱)
UIDevice.current.model = iPhone
UIDevice.current.systemName = iOS
UIDevice.current.systemVersion = 11.2
UIDevice.current.identifierForVendor! = E6B52865-0F8E-4773-BF42-E40E2C37F472
iPhone 6 的結果：
app_dDisplayName = helloApp
app_version = 1.0
app_build = 1
UIDevice.current.name = _helloiphone
UIDevice.current.model = iPhone
UIDevice.current.systemName = iOS
UIDevice.current.systemVersion = 11.2.6
UIDevice.current.identifierForVendor! = 2057AEC2-91F6-44D4-8D32-36CDFE2638D0
另外，要得知 iOS 的設備型號
參考
https://stackoverflow.com/questions/24059327/detect-current-device-with-ui-user-interface-idiom-in-swift/40083017
let userInterface = UIDevice.current.userInterfaceIdiom
if userInterface == .pad {
print("iPad")
} else if userInterface == .phone {
print("iPhone")
} else if userInterface == .carPlay {
print("CartPlay")
} else if userInterface == .tv {
print("AppleTV")
}
public extension UIDevice {
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 where 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 "iPhone6,1", "iPhone6,2": return "iPhone 5s"
case "iPhone7,2": return "iPhone 6"
case "iPhone7,1": return "iPhone 6 Plus"
case "iPhone8,1": return "iPhone 6s"
case "iPhone8,2": return "iPhone 6s Plus"
case "iPhone9,1", "iPhone9,3": return "iPhone 7"
case "iPhone9,2", "iPhone9,4": return "iPhone 7 Plus"
case "iPhone8,4": return "iPhone SE"
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 "iPad6,3", "iPad6,4", "iPad6,7", "iPad6,8":return "iPad Pro"
case "AppleTV5,3": return "Apple TV"
case "i386", "x86_64": return "Simulator"
default: return identifier
}
}
}
This is how you will use it:
let modelName = UIDevice.currentDevice().modelName
另外
if #available(iOS 10.0, *) {
// iOS 10.0 (含)以上 或 其它作業系統 執行這裡
}
* 星號 指的是其它作業系統
或這樣寫
@available(iOS 10.0, OSX 10.10, *)
func myMethod() { // iOS 10.0 (含)以上 或 OSX 10.10（含)以上 或 其它作業系統 執行這裡
...
}
或這樣
@available(iOS 10.0, *)
func myMethod() {
...
}
還有
@available(swift 3.0.2)
struct MyStruct {
// struct definition
}
if #available(tvOS 1.0, *) {
}
if #available(watchOS 1.0, *) {
}
if #available(OSX 10.11, *) {
}
