IOS Devices Version
游戏项目中有一个专门用于收集IOS崩溃的接口和查询页，运营/测试的同事有时候会通过查询页大概看一下每日崩溃的情况，经常会问iPhone6,1是什么，iPhone7,1又是什么设备？
我从网上仔细搜索了一下，目前最全的是来自维基百科的：List of iOS devices
其中Hardware strings这一栏目前是最全的，iPhone后面第一位数字表示的是第几代iPhone，比如上面的7，表示第7代iphone，也就是iphone6。下面来列一下iphone设备列表
| Apple iPhone | Hardware identifier |
| iPhone(Original/1st Gen/EDGE) | iPhone1,1 |
| iPhone 3G | iPhone1,2 |
| iPhone 3GS | iPhone2,1 |
| iPhone 3G(China/No Wi-Fi) | iPhone1,2 |
| iPhone 3GS(China/No Wi-Fi) | iPhone2,1 |
| iPhone 4(GSM) | iPhone3,1 |
| iPhone 4 (CDMA/Verizon/Sprint) | iPhone3,3 |
| iPhone 4S | iPhone4,1 |
| iPhone 5 (GSM/LTE 4, 17/North America) | iPhone5,1 |

每一代Phone，都有很多不同的版本，比如韩版、欧版、港版的区分，iPad更有3G/WiFi的区分，所以上述方法只能判断出当前设备大概是什么型号，不是很精准，针对某些设置上才出现的bug，可能需要更深入的一些细分了。不过，通常来看，设备型号 + IOS系统版本，基本上就很容易复现问题了，越狱对bug的影响越来越小。
今年，Apple Watch又发布了，所以又加了俩：Watch1,1、Watch1,2(鉴于watch的屏幕、性能限制，暂时没什么游戏能上的去，可以忽略)，除此之外，还有Apple TV，貌似在国内还没啥市场也可以暂时忽略。上面列表也只是列出了iPhone、iPad，其它的还有iPod touch，有兴趣可以参考这里：

这里提供一份示例代码：
- (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:@"iPhone3,3"]) return @"Verizon iPhone 4";
if ([platform isEqualToString:@"iPhone4,1"]) return @"iPhone 4S";
if ([platform isEqualToString:@"iPhone5,1"]) return @"iPhone 5 (GSM)";
if ([platform isEqualToString:@"iPhone5,2"]) return @"iPhone 5 (GSM+CDMA)";
if ([platform isEqualToString:@"iPhone5,3"]) return @"iPhone 5c (GSM)";
if ([platform isEqualToString:@"iPhone5,4"]) return @"iPhone 5c (GSM+CDMA)";
