我在寻找最官方的来源来完成/维护这种方法:
-(NSString*)platformString
{
NSString *platform = [self platform];
if ([platform isEqualToString:@"iPhone1,1"]) return @"iPhone 1G";
if ([platform isEqualToString:@"iPhone1,2"]) return @"iPhone 3G";
if ([platform isEqualToString:@"iPhone2,1"]) return @"iPhone 3GS";
if ([platform isEqualToString:@"iPhone3,1"]) return @"iPhone 4";
if ([platform isEqualToString:@"iPhone3,2"]) return @"iPhone 4 (Other Carrier)";
if ([platform isEqualToString:@"iPhone3,3"]) return @"iPhone 4 CDMA";
if ([platform isEqualToString:@"iPhone4,1"]) return @"iPhone 4S";
if ([platform isEqualToString:@"iPhone5,1"]) return @"iPhone 5";
if ([platform isEqualToString:@"iPod1,1"]) return @"iPod Touch 1G";
if ([platform isEqualToString:@"iPod2,1"]) return @"iPod Touch 2G";
if ([platform isEqualToString:@"iPod3,1"]) return @"iPod Touch 3G";
if ([platform isEqualToString:@"iPod4,1"]) return @"iPod Touch 4G";
if ([platform isEqualToString:@"iPod5,1"]) return @"iPod Touch 5G";
if ([platform isEqualToString:@"iPad1,1"]) return @"iPad";
if ([platform isEqualToString:@"iPad2,1"]) return @"iPad 2 WiFi";
if ([platform isEqualToString:@"iPad2,2"]) return @"iPad 2 GSM";
if ([platform isEqualToString:@"iPad2,3"]) return @"iPad 2 CDMA";
if ([platform isEqualToString:@"iPad2,4"]) return @"iPad 2 CDMAS";
if ([platform isEqualToString:@"iPad2,5"]) return @"iPad Mini Wifi";
if ([platform isEqualToString:@"iPad2,6"]) return @"iPad mini (Cellular ATT)";
if ([platform isEqualToString:@"iPad2,7"]) return @"iPad mini (Cellular Verizon)";
if ([platform isEqualToString:@"iPad3,1"]) return @"iPad 3 WiFi";
if ([platform isEqualToString:@"iPad3,2"]) return @"iPad 3 CDMA";
if ([platform isEqualToString:@"iPad3,3"]) return @"iPad 3 GSM";
if ([platform isEqualToString:@"iPad3,4"]) return @"iPad 4 Wifi";
if ([platform isEqualToString:@"iPad3,5"]) return @"iPad 3 (Cellular ATT)";
if ([platform isEqualToString:@"iPad3,6"]) return @"iPad 3 (Cellular Verizon)";
if ([platform isEqualToString:@"iPad4,1"]) return @"iPad 4 WiFi";
if ([platform isEqualToString:@"iPad4,2"]) return @"iPad 4 GSM";
if ([platform isEqualToString:@"iPad4,3"]) return @"iPad 4 CDMA";
if ([platform isEqualToString:@"i386"]) return @"Simulator";
if ([platform isEqualToString:@"x86_64"]) return @"Simulator";
return [NSString stringWithFormat:@"Unknown: %@", platform];
}
苹果公司是否就此发表过声明?
或者有一些经验丰富的研究人员在某个地方做过相关调查吗?
为了澄清,我正在使用以下代码:
-(NSString*)getSysInfoByName:(char*) typeSpecifier
{
size_t size;
sysctlbyname(typeSpecifier, NULL, &size, NULL, 0);
char *answer = malloc(size);
sysctlbyname(typeSpecifier, answer, &size, NULL, 0);
NSString *results = [NSString stringWithCString:answer encoding: NSUTF8StringEncoding];
free(answer);
return results;
}
-(NSString*)platform
{ return [self getSysInfoByName:"hw.machine"]; }
