iOS获取设备型号和App版本号等信息(OC+Swift)

好久没有写过博客了,因为中间工作比较忙,然后有些个人事情所以耽误了。但是之前写的博客还一直有人来问一些问题,有些之前写的已经比较久了,有些需要实时更新的也没来得及更新,发现会跟一些童鞋造成困惑,所以以后也希望能及时更新和写一些新的内容。

我之前博客的地址:一毛的博客,也是主要介绍iOS开发的,以后都在简书更新吧。希望大家能继续支持。

iOS开发过程中,有时候为了更好的用户体验或者为了bug跟踪,可能会需要获取用户的应用信息、系统信息、设备信息。这些信息的获取可以根据不同的设备或者App、系统版本来提供不同的功能或更好的用户体验,或者让开发者能更好的分析用户的问题原因。

你说不要啰嗦了:Talk is cheap, show me the code!

好的,code来了:

  1. 获取设备名称

    OC代码
    NSString *deviceName = [[UIDevice currentDevice] name];

    Swift代码
    let deviceName = UIDevice.currentDevice().name

  2. 获取系统版本号

    OC代码
    NSString *sysVersion = [[UIDevice currentDevice] systemVersion];

    Swift代码
    let sysVersion = UIDevice.currentDevice().systemVersion

  3. 获取设备唯一标识符

    OC代码
    NSString *deviceUUID = [[[UIDevice currentDevice] identifierForVendor] UUIDString];

    Swift代码
    let deviceUUID = UIDevice.currentDevice().identifierForVendor?.UUIDString

  4. 获取设备的型号

    OC代码
    NSString *deviceModel = [[UIDevice currentDevice] model];

    Swift代码
    let deviceModel = UIDevice.currentDevice().model

  5. 获取App相关的信息

    OC代码

    NSDictionary *infoDic = [[NSBundle mainBundle] infoDictionary];
    
    // 获取App的版本号
    NSString *appVersion = [infoDic objectForKey:@"CFBundleShortVersionString"];
    
    // 获取App的build版本
    NSString *appBuildVersion = [infoDic objectForKey:@"CFBundleVersion"];
    
    // 获取App的名称
    NSString *appName = [infoDic objectForKey:@"CFBundleDisplayName"];
    

    Swift代码

    let infoDic = NSBundle.mainBundle().infoDictionary
    
    // 获取App的版本号
    let appVersion = infoDic?["CFBundleShortVersionString"]
    
    // 获取App的build版本
    let appBuildVersion = infoDic?["CFBundleVersion"]
    
    // 获取App的名称
    let appName = infoDic?["CFBundleDisplayName"]
    

有些人可能会说了:“裤子都脱了,你就给我看这个!看你之前写的博客还能看点儿干货,今天第一篇就写着么个玩意儿?尤其是获取设备型号那个,获取出来一个iPhone,你确定不是在逗我吧?”

看官别急,其实这次最主要的就是来分享获取设备型号的方法的,因为我看国内还很少有Swift写的一些东西,也不知道是不是因为我没有找到,就想自己写出来给大家分享,顺便做个笔记。

你会说:获取设备型号比较麻烦,又用的是C语言的一些东西,比较麻烦,而且还得记住所有设备版本号例如:iPhone8,2,实在是记不住啊。当然不用记住,用的时候拷过来就行了,因为我也记不住😄

iOS获取具体设备型号

OC代码获取iOS设备型号:

// 需要#import <sys/utsname.h>
+ (NSString*)deviceModelName
{
    struct utsname systemInfo;
    uname(&systemInfo);
    NSString *deviceModel = [NSString stringWithCString:systemInfo.machine encoding:NSUTF8StringEncoding];
    
    //iPhone 系列
    if ([deviceModel isEqualToString:@"iPhone1,1"])    return @"iPhone 1G";
    if ([deviceModel isEqualToString:@"iPhone1,2"])    return @"iPhone 3G";
    if ([deviceModel isEqualToString:@"iPhone2,1"])    return @"iPhone 3GS";
    if ([deviceModel isEqualToString:@"iPhone3,1"])    return @"iPhone 4";
    if ([deviceModel isEqualToString:@"iPhone3,2"])    return @"Verizon iPhone 4";
    if ([deviceModel isEqualToString:@"iPhone4,1"])    return @"iPhone 4S";
    if ([deviceModel isEqualToString:@"iPhone5,1"])    return @"iPhone 5";
    if ([deviceModel isEqualToString:@"iPhone5,2"])    return @"iPhone 5";
    if ([deviceModel isEqualToString:@"iPhone5,3"])    return @"iPhone 5C";
    if ([deviceModel isEqualToString:@"iPhone5,4"])    return @"iPhone 5C";
    if ([deviceModel isEqualToString:@"iPhone6,1"])    return @"iPhone 5S";
    if ([deviceModel isEqualToString:@"iPhone6,2"])    return @"iPhone 5S";
    if ([deviceModel isEqualToString:@"iPhone7,1"])    return @"iPhone 6 Plus";
    if ([deviceModel isEqualToString:@"iPhone7,2"])    return @"iPhone 6";
    if ([deviceModel isEqualToString:@"iPhone8,1"])    return @"iPhone 6s";
    if ([deviceModel isEqualToString:@"iPhone8,2"])    return @"iPhone 6s Plus";
    if ([deviceModel isEqualToString:@"iPhone9,1"])    return @"iPhone 7 (CDMA)";
    if ([deviceModel isEqualToString:@"iPhone9,3"])    return @"iPhone 7 (GSM)";
    if ([deviceModel isEqualToString:@"iPhone9,2"])    return @"iPhone 7 Plus (CDMA)";
    if ([deviceModel isEqualToString:@"iPhone9,4"])    return @"iPhone 7 Plus (GSM)";

    //iPod 系列
    if ([deviceModel isEqualToString:@"iPod1,1"])      return @"iPod Touch 1G";
    if ([deviceModel isEqualToString:@"iPod2,1"])      return @"iPod Touch 2G";
    if ([deviceModel isEqualToString:@"iPod3,1"])      return @"iPod Touch 3G";
    if ([deviceModel isEqualToString:@"iPod4,1"])      return @"iPod Touch 4G";
    if ([deviceModel isEqualToString:@"iPod5,1"])      return @"iPod Touch 5G";
    
    //iPad 系列
    if ([deviceModel isEqualToString:@"iPad1,1"])      return @"iPad";
    if ([deviceModel isEqualToString:@"iPad2,1"])      return @"iPad 2 (WiFi)";
    if ([deviceModel isEqualToString:@"iPad2,2"])      return @"iPad 2 (GSM)";
    if ([deviceModel isEqualToString:@"iPad2,3"])      return @"iPad 2 (CDMA)";
    if ([deviceModel isEqualToString:@"iPad2,4"])      return @"iPad 2 (32nm)";
    if ([deviceModel isEqualToString:@"iPad2,5"])      return @"iPad mini (WiFi)";
    if ([deviceModel isEqualToString:@"iPad2,6"])      return @"iPad mini (GSM)";
    if ([deviceModel isEqualToString:@"iPad2,7"])      return @"iPad mini (CDMA)";
    
    if ([deviceModel isEqualToString:@"iPad3,1"])      return @"iPad 3(WiFi)";
    if ([deviceModel isEqualToString:@"iPad3,2"])      return @"iPad 3(CDMA)";
    if ([deviceModel isEqualToString:@"iPad3,3"])      return @"iPad 3(4G)";
    if ([deviceModel isEqualToString:@"iPad3,4"])      return @"iPad 4 (WiFi)";
    if ([deviceModel isEqualToString:@"iPad3,5"])      return @"iPad 4 (4G)";
    if ([deviceModel isEqualToString:@"iPad3,6"])      return @"iPad 4 (CDMA)";
    
    if ([deviceModel isEqualToString:@"iPad4,1"])      return @"iPad Air";
    if ([deviceModel isEqualToString:@"iPad4,2"])      return @"iPad Air";
    if ([deviceModel isEqualToString:@"iPad4,3"])      return @"iPad Air";
    if ([deviceModel isEqualToString:@"iPad5,3"])      return @"iPad Air 2";
    if ([deviceModel isEqualToString:@"iPad5,4"])      return @"iPad Air 2";
    if ([deviceModel isEqualToString:@"i386"])         return @"Simulator";
    if ([deviceModel isEqualToString:@"x86_64"])       return @"Simulator";
    
    if ([deviceModel isEqualToString:@"iPad4,4"]
        ||[deviceModel isEqualToString:@"iPad4,5"]
        ||[deviceModel isEqualToString:@"iPad4,6"])      return @"iPad mini 2";
    
    if ([deviceModel isEqualToString:@"iPad4,7"]
        ||[deviceModel isEqualToString:@"iPad4,8"]
        ||[deviceModel isEqualToString:@"iPad4,9"])      return @"iPad mini 3";
    
    return deviceModel;
}

记得一定要#import <sys/utsname.h>啊,到时候没有导入编译不通过了不要找我啊。

Swift代码获取iOS设备型号:

//MARK: - UIDevice延展
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 "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":                               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
        }
    }
    
}

这个是在 Swift 2.0 版本之后才能使用的:现在不会还有人使用 Swift 1.2 吧?

你还问我怎么用?好吧,骚年,送佛送到西,您看好了,把上面的扩展扔到你的项目中,然后就可以用下面的语句调用了:

let modelName = UIDevice.currentDevice().modelName

好了,今天就写到这儿吧,希望以后还有时间有精力来更多的更新一些内容吧。

再次谢谢大家的支持!也希望哪儿有写的不对的地方,欢迎大家批评指正。
