好久沒有寫過博客了，因?yàn)橹虚g工作比較忙，然后有些個人事情所以耽誤了。但是之前寫的博客還一直有人來問一些問題，有些之前寫的已經(jīng)比較久了，有些需要實(shí)時更新的也沒來得及更新，發(fā)現(xiàn)會跟一些童鞋造成困惑，所以以后也希望能及時更新和寫一些新的內(nèi)容。

我之前博客的地址：一毛的博客，也是主要介紹iOS開發(fā)的，以后都在簡書更新吧。希望大家能繼續(xù)支持。

iOS開發(fā)過程中，有時候?yàn)榱烁玫挠脩趔w驗(yàn)或者為了bug跟蹤，可能會需要獲取用戶的應(yīng)用信息、系統(tǒng)信息、設(shè)備信息。這些信息的獲取可以根據(jù)不同的設(shè)備或者App、系統(tǒng)版本來提供不同的功能或更好的用戶體驗(yàn)，或者讓開發(fā)者能更好的分析用戶的問題原因。

你說不要啰嗦了：Talk is cheap, show me the code！

好的，code來了：

獲取設(shè)備名稱

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

Swift代碼
let deviceName = UIDevice.currentDevice().name
獲取系統(tǒng)版本號

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

Swift代碼
let sysVersion = UIDevice.currentDevice().systemVersion
獲取設(shè)備唯一標(biāo)識符

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

Swift代碼
let deviceUUID = UIDevice.currentDevice().identifierForVendor?.UUIDString
獲取設(shè)備的型號

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

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

獲取App相關(guān)的信息

OC代碼

NSDictionary *infoDic = [[NSBundle mainBundle] infoDictionary];

// 獲取App的版本號
NSString *appVersion = [infoDic objectForKey:@"CFBundleShortVersionString"];

// 獲取App的build版本
NSString *appBuildVersion = [infoDic objectForKey:@"CFBundleVersion"];

// 獲取App的名稱
NSString *appName = [infoDic objectForKey:@"CFBundleDisplayName"];

Swift代碼

let infoDic = NSBundle.mainBundle().infoDictionary

// 獲取App的版本號
let appVersion = infoDic?["CFBundleShortVersionString"]

// 獲取App的build版本
let appBuildVersion = infoDic?["CFBundleVersion"]

// 獲取App的名稱
let appName = infoDic?["CFBundleDisplayName"]

有些人可能會說了：“褲子都脫了，你就給我看這個！看你之前寫的博客還能看點(diǎn)兒干貨，今天第一篇就寫著么個玩意兒？尤其是獲取設(shè)備型號那個，獲取出來一個iPhone，你確定不是在逗我吧？”

看官別急，其實(shí)這次最主要的就是來分享獲取設(shè)備型號的方法的，因?yàn)槲铱磭鴥?nèi)還很少有Swift寫的一些東西，也不知道是不是因?yàn)槲覜]有找到，就想自己寫出來給大家分享，順便做個筆記。

你會說：獲取設(shè)備型號比較麻煩，又用的是C語言的一些東西，比較麻煩，而且還得記住所有設(shè)備版本號例如：iPhone8,2，實(shí)在是記不住啊。當(dāng)然不用記住，用的時候拷過來就行了，因?yàn)槲乙灿洸蛔??

iOS獲取具體設(shè)備型號

OC代碼獲取iOS設(shè)備型號：

// 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:@"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;
}

記得一定要#import <sys/utsname.h>啊，到時候沒有導(dǎo)入編譯不通過了不要找我啊。

Swift代碼獲取iOS設(shè)備型號：

//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 "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 "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
        }
    }
    
}

這個是在 Swift 2.0 版本之后才能使用的：現(xiàn)在不會還有人使用 Swift 1.2 吧？

你還問我怎么用？好吧，騷年，送佛送到西，您看好了，把上面的擴(kuò)展扔到你的項(xiàng)目中，然后就可以用下面的語句調(diào)用了：

let modelName = UIDevice.currentDevice().modelName

好了，今天就寫到這兒吧，希望以后還有時間有精力來更多的更新一些內(nèi)容吧。

再次謝謝大家的支持！也希望哪兒有寫的不對的地方，歡迎大家批評指正。
