如何识别iOS不同设备

- (NSString *) platformString

{

    size_t size;

    sysctlbyname("hw.machine", NULL, &size, NULL, 0);

    char *machine = malloc(size);

    sysctlbyname("hw.machine", machine, &size, NULL, 0);

    NSString *platform = [NSString stringWithUTF8String:machine];

    free(machine);

    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:@"iPhone3,3"])    return @"Verizon iPhone 4";

    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:@"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:@"i386"])         return @"Simulator";

    return @"";

}

在添加一些收集到的

//iPhone
    if ([deviceString isEqualToString:@"iPhone4,1"])    return @"iPhone 4S";
    if ([deviceString isEqualToString:@"iPhone5,1"])    return @"iPhone 5(AT&T)";
    if ([deviceString isEqualToString:@"iPhone5,2"])    return @"iPhone 5(GSM/CDMA)";
//iPod Touch
    if ([deviceString isEqualToString:@"iPod5,1"])      return @"iPod Touch 5G";
//iPad
    if ([deviceString isEqualToString:@"iPad2,5"])      return @"iPad Mini (WiFi)";
    if ([deviceString isEqualToString:@"iPad2,6"])      return @"iPad Mini (GSM)";
    if ([deviceString isEqualToString:@"iPad2,7"])      return @"iPad Mini (CDMA)";
    if ([deviceString isEqualToString:@"iPad3,1"])      return @"iPad 3 (WiFi)";
    if ([deviceString isEqualToString:@"iPad3,2"])      return @"iPad 3 (GSM)";
    if ([deviceString isEqualToString:@"iPad3,3"])      return @"iPad 3 (CDMA)";

    if ([deviceString isEqualToString:@"iPad3,5"])      return @"iPad 4 (GSM)";
    if ([deviceString isEqualToString:@"iPad3,6"])      return @"iPad 4 (CDMA)";
//Simulator
    if ([deviceString isEqualToString:@"i386"])         return @"Simulator";
    if ([deviceString isEqualToString:@"x86_64"])       return @"Simulator";

转载的没有那么多个机型逐个实验.所以不敢保证都正确.
