獲取iOS設備的相關信息

之所以要寫這篇文章是因爲最近做項目要獲取iOS設備的相關信息，而從網上找的不是差這點就是差那點，沒有全的，所以爲了方便其他開發者，我把獲取iOS設備的相關信息的方法總結下。剛開始寫，以後還會持續更新的。（出新設備時我會及時添加的，如果有什麼疑問歡迎加我QQ：295768361 一起討論移動應用開發，共同進步）

1.獲取iOS設備的機型

最好是寫個NSString的分類，到時候那裏不會點哪裏，媽媽再也不用擔心我的學習了。

// #import "sys/utsname.h"
- (NSString *)deviceHardwareString {

    struct utsname systemInfo;
    uname(&systemInfo);
    NSString *platform = [NSString stringWithCString:systemInfo.machine encoding:NSUTF8StringEncoding];

    if ([platform isEqualToString:@"iPhone1,1"]) return @"iPhone 2G (A1203)";
    if ([platform isEqualToString:@"iPhone1,2"]) return @"iPhone 3G (A1241/A1324)";
    if ([platform isEqualToString:@"iPhone2,1"]) return @"iPhone 3GS (A1303/A1325)";
    if ([platform isEqualToString:@"iPhone3,1"]) return @"iPhone 4 (A1332)";
    if ([platform isEqualToString:@"iPhone3,2"]) return @"iPhone 4 (A1332)";
    if ([platform isEqualToString:@"iPhone3,3"]) return @"iPhone 4 (A1349)";
    if ([platform isEqualToString:@"iPhone4,1"]) return @"iPhone 4S (A1387/A1431)";
    if ([platform isEqualToString:@"iPhone5,1"]) return @"iPhone 5 (A1428)";
    if ([platform isEqualToString:@"iPhone5,2"]) return @"iPhone 5 (A1429/A1442)";
    if ([platform isEqualToString:@"iPhone5,3"]) return @"iPhone 5c (A1456/A1532)";
    if ([platform isEqualToString:@"iPhone5,4"]) return @"iPhone 5c (A1507/A1516/A1526/A1529)";
    if ([platform isEqualToString:@"iPhone6,1"]) return @"iPhone 5s (A1453/A1533)";
    if ([platform isEqualToString:@"iPhone6,2"]) return @"iPhone 5s (A1457/A1518/A1528/A1530)";
    if ([platform isEqualToString:@"iPhone7,1"]) return @"iPhone 6 Plus (A1522/A1524)";
    if ([platform isEqualToString:@"iPhone7,2"]) return @"iPhone 6 (A1549/A1586)";
    if ([platform isEqualToString:@"iPhone8,1"]) return @"iPhone 6s";
    if ([platform isEqualToString:@"iPhone8,2"]) return @"iPhone 6s Plus";
    if ([platform isEqualToString:@"iPhone8,4"]) return @"iPhone SE";
    if ([platform isEqualToString:@"iPhone9,1"]) return @"IPhone 7";
    if ([platform isEqualToString:@"iPhone9,3"]) return @"IPhone 7 TEMP";
    if ([platform isEqualToString:@"iPhone9,2"]) return @"IPhone 7 Plus";
    if ([platform isEqualToString:@"iPhone9,4"]) return @"IPhone 7 Plus TEMP";

    if ([platform isEqualToString:@"iPod1,1"])   return @"iPod Touch 1G (A1213)";
    if ([platform isEqualToString:@"iPod2,1"])   return @"iPod Touch 2G (A1288)";
    if ([platform isEqualToString:@"iPod3,1"])   return @"iPod Touch 3G (A1318)";
    if ([platform isEqualToString:@"iPod4,1"])   return @"iPod Touch 4G (A1367)";
    if ([platform isEqualToString:@"iPod5,1"])   return @"iPod Touch 5G (A1421/A1509)";

    if ([platform isEqualToString:@"iPad1,1"])   return @"iPad 1G (A1219/A1337)";

    if ([platform isEqualToString:@"iPad2,1"])   return @"iPad 2 (A1395)";
    if ([platform isEqualToString:@"iPad2,2"])   return @"iPad 2 (A1396)";
    if ([platform isEqualToString:@"iPad2,3"])   return @"iPad 2 (A1397)";
    if ([platform isEqualToString:@"iPad2,4"])   return @"iPad 2 (A1395+New Chip)";
    if ([platform isEqualToString:@"iPad2,5"])   return @"iPad Mini 1G (A1432)";
    if ([platform isEqualToString:@"iPad2,6"])   return @"iPad Mini 1G (A1454)";
    if ([platform isEqualToString:@"iPad2,7"])   return @"iPad Mini 1G (A1455)";

    if ([platform isEqualToString:@"iPad3,1"])   return @"iPad 3 (A1416)";
    if ([platform isEqualToString:@"iPad3,2"])   return @"iPad 3 (A1403)";
    if ([platform isEqualToString:@"iPad3,3"])   return @"iPad 3 (A1430)";
    if ([platform isEqualToString:@"iPad3,4"])   return @"iPad 4 (A1458)";
    if ([platform isEqualToString:@"iPad3,5"])   return @"iPad 4 (A1459)";
    if ([platform isEqualToString:@"iPad3,6"])   return @"iPad 4 (A1460)";

    if ([platform isEqualToString:@"iPad4,1"])   return @"iPad Air (A1474)";
    if ([platform isEqualToString:@"iPad4,2"])   return @"iPad Air (A1475)";
    if ([platform isEqualToString:@"iPad4,3"])   return @"iPad Air (A1476)";
    if ([platform isEqualToString:@"iPad4,4"])   return @"iPad Mini 2G (A1489)";
    if ([platform isEqualToString:@"iPad4,5"])   return @"iPad Mini 2G (A1490)";
    if ([platform isEqualToString:@"iPad4,6"])   return @"iPad Mini 2G (A1491)";

    if ([platform isEqualToString:@"i386"])      return @"iPhone Simulator";
    if ([platform isEqualToString:@"x86_64"])    return @"iPhone Simulator";
    return platform;//未知型號
}
 ```

2.判斷手機運營商

CTTelephonyNetworkInfo * NetworkInfo = [[CTTelephonyNetworkInfo alloc]init];
NSString * NetworkCode = [[NetworkInfo subscriberCellularProvider] mobileNetworkCode];

其中當NetworkCode的值：
爲“00” 則表示China Mobile
“01” 則表示China Unicom
“02” 則表示China Mobile
“03” 則表示China Telecom
“05” 則表示China Telecom
“06” 則表示China Unicon
“07” 則表示 China Mobile
“20” 則表示ChinaTietong
“”
判斷設備連接的是那種的蜂窩網絡：
NetworkInfo.currentRadioAccessTechnology
或得出當前所連接的是那種的蜂窩網絡，比如Edge網絡，HSDPA無網絡或者LTE網絡。
