？Swift获取手机设备信息

使用UiDevice获取设备信息：

获取设备名称

let name = UIDevice.currentDevice().name

获取设备系统名称

let systemName = UIDevice.currentDevice().systemName

获取系统版本

let systemVersion = UIDevice.currentDevice().systemVersion

获取设备模型

let model = UIDevice.currentDevice().model

获取设备本地模型

let localizedModel = UIDevice.currentDevice().localizedModel

Swift获取Bundle的相关信息：

let infoDict = NSBundle.mainBundle().infoDictionary
if let info = infoDict? {
    // app名称
    let appName = info["CFBundleName"] as String!
    // app版本
    let appVersion = info["CFBundleShortVersionString"] as String!
    // app build版本
    let appBuild = info["CFBundleVersion"] as String!
}
