iOS获取设备信息

这里总结一下常用的，获取设备信息的方法：
直接上代码：

- (NSString *)getDeviceName{
//获取设备名称
//需先导入#import "sys/utsname.h"
struct utsname systemInfo;
uname(&systemInfo);

NSString *deviceString = [NSString stringWithCString:systemInfo.machine encoding:NSUTF8StringEncoding];
if ([deviceString isEqualToString:@"iPhone3,1"])    return @"iPhone 4";
if ([deviceString isEqualToString:@"iPhone3,2"])    return @"iPhone 4";
if ([deviceString isEqualToString:@"iPhone3,3"])    return @"iPhone 4";
if ([deviceString isEqualToString:@"iPhone4,1"])    return @"iPhone 4S";
if ([deviceString isEqualToString:@"iPhone5,1"])    return @"iPhone 5";
if ([deviceString isEqualToString:@"iPhone5,2"])    return @"iPhone 5 (GSM+CDMA)";
if ([deviceString isEqualToString:@"iPhone5,3"])    return @"iPhone 5c (GSM)";
if ([deviceString isEqualToString:@"iPhone5,4"])    return @"iPhone 5c (GSM+CDMA)";
if ([deviceString isEqualToString:@"iPhone6,1"])    return @"iPhone 5s (GSM)";
if ([deviceString isEqualToString:@"iPhone6,2"])    return @"iPhone 5s (GSM+CDMA)";
if ([deviceString isEqualToString:@"iPhone7,1"])    return @"iPhone 6 Plus";
if ([deviceString isEqualToString:@"iPhone7,2"])    return @"iPhone 6";
if ([deviceString isEqualToString:@"iPhone8,1"])    return @"iPhone 6s";
if ([deviceString isEqualToString:@"iPhone8,2"])    return @"iPhone 6s Plus";
if ([deviceString isEqualToString:@"iPhone8,4"])    return @"iPhone SE";

if ([deviceString isEqualToString:@"iPod1,1"])      return @"iPod Touch 1G";
if ([deviceString isEqualToString:@"iPod2,1"])      return @"iPod Touch 2G";
if ([deviceString isEqualToString:@"iPod3,1"])      return @"iPod Touch 3G";
if ([deviceString isEqualToString:@"iPod4,1"])      return @"iPod Touch 4G";
if ([deviceString isEqualToString:@"iPod5,1"])      return @"iPod Touch (5 Gen)";

if ([deviceString isEqualToString:@"iPad1,1"])      return @"iPad";
if ([deviceString isEqualToString:@"iPad1,2"])      return @"iPad 3G";
if ([deviceString isEqualToString:@"iPad2,1"])      return @"iPad 2 (WiFi)";
if ([deviceString isEqualToString:@"iPad2,2"])      return @"iPad 2";
if ([deviceString isEqualToString:@"iPad2,3"])      return @"iPad 2 (CDMA)";
if ([deviceString isEqualToString:@"iPad2,4"])      return @"iPad 2";

if ([deviceString isEqualToString:@"iPad2,7"])      return @"iPad Mini (GSM+CDMA)";
if ([deviceString isEqualToString:@"iPad3,1"])      return @"iPad 3 (WiFi)";
if ([deviceString isEqualToString:@"iPad3,2"])      return @"iPad 3 (GSM+CDMA)";
if ([deviceString isEqualToString:@"iPad3,3"])      return @"iPad 3";
if ([deviceString isEqualToString:@"iPad3,4"])      return @"iPad 4 (WiFi)";
if ([deviceString isEqualToString:@"iPad3,5"])      return @"iPad 4";
if ([deviceString isEqualToString:@"iPad3,6"])      return @"iPad 4 (GSM+CDMA)";
if ([deviceString isEqualToString:@"iPad4,1"])      return @"iPad Air (WiFi)";
if ([deviceString isEqualToString:@"iPad4,2"])      return @"iPad Air (Cellular)";
if ([deviceString isEqualToString:@"iPad4,4"])      return @"iPad Mini 2 (WiFi)";
if ([deviceString isEqualToString:@"iPad4,5"])      return @"iPad Mini 2 (Cellular)";
if ([deviceString isEqualToString:@"iPad4,6"])      return @"iPad Mini 2";
if ([deviceString isEqualToString:@"iPad4,7"])      return @"iPad Mini 3";
if ([deviceString isEqualToString:@"iPad4,8"])      return @"iPad Mini 3";
if ([deviceString isEqualToString:@"iPad4,9"])      return @"iPad Mini 3";
if ([deviceString isEqualToString:@"iPad5,1"])      return @"iPad Mini 4 (WiFi)";
if ([deviceString isEqualToString:@"iPad5,2"])      return @"iPad Mini 4 (LTE)";
if ([deviceString isEqualToString:@"iPad5,3"])      return @"iPad Air 2";
if ([deviceString isEqualToString:@"iPad5,4"])      return @"iPad Air 2";
if ([deviceString isEqualToString:@"iPad6,3"])      return @"iPad Pro 9.7";
if ([deviceString isEqualToString:@"iPad6,4"])      return @"iPad Pro 9.7";
if ([deviceString isEqualToString:@"iPad6,7"])      return @"iPad Pro 12.9";
if ([deviceString isEqualToString:@"iPad6,8"])      return @"iPad Pro 12.9";

if ([deviceString isEqualToString:@"i386"])         return @"Simulator";
if ([deviceString isEqualToString:@"x86_64"])       return @"Simulator";

return deviceString;
