iOS获取设备型号、设备类型等信息
关于设备标识，历史上盛行过很多英雄，比如UDID、Mac地址、OpenUDID等，然而他们都陆陆续续倒在了苹果的门下。苹果目前提供了2个方法供App获取设备标识：idfa和idfv
idfa：全称advertisingIdentifier，官方解释是广告标识，适用于广告推广，这个建议不要轻易使用，如果用了，则App里必须提供广告功能，否则很有可能会在AppStore审核时被拒。而且idfa是可以被用户关闭的（设置-》隐私），一旦被关闭，就获取不到了。
idfv：全称identifierForVendor，按照字面意思理解，相同的Vendor应该有相同的identifier。Vendor是根据app的bundleid的前两位来界定的，比如对于com.abc.app1和com.abc.app2这2个bundleid的app来说，他们就属于同一个vendor。idfv是一定可以获取到的。需要注意的一点是，当用户将某个vendor下的所有app都卸载掉时，idfv就会被重置，再次安装时，获取到的idfv会跟之前的不一样。所以我用的方案是：idfv+keychain。当然如果用户选择恢复出厂设置，那么还是会出现不一样，这种情况就没法处理了。
1 +(NSString *)identifier 2 { 3 NSString *key = @"com.app.keychain.uuid"; 4 KeychainItemWrapper *keychainItem = [[KeychainItemWrapper alloc] initWithIdentifier:key accessGroup:nil]; 5 6 NSString *strUUID = [keychainItem objectForKey:(__bridge id)kSecValueData]; 7 8 if (strUUID.length <= 0) { 9 strUUID = [[[UIDevice currentDevice] identifierForVendor] UUIDString]; 10 11 [keychainItem setObject:@"uuid" forKey:(__bridge id)kSecAttrAccount]; 12 [keychainItem setObject:strUUID forKey:(__bridge id)kSecValueData]; 13 } 14 15 return strUUID; 16 }
手机别名
1 +(NSString *)phoneName 2 { 3 return [[UIDevice currentDevice] name]; 4 }
1 /** 2 * 手机系统版本 3 * 4 * @return e.g. 8.0 5 */ 6 +(NSString *)phoneVersion{ 7 return [[UIDevice currentDevice] systemVersion]; 8 }
这个方法只能获取到iPhone、iPad这种信息，无法获取到是iPhone 4、iPhpone5这种具体的型号。
1 /** 2 * 手机型号 3 * 4 * @return e.g. iPhone 5 */ 6 +(NSString *)phoneModel{ 7 return [[UIDevice currentDevice] model]; 8 }
这个代码可以获取到具体的设备版本（已更新到iPhone 6s、iPhone 6s Plus），缺点是：采用的硬编码。具体的对应关系可以参考：https://www.theiphonewiki.com/wiki/Models
这个方法可以通过AppStore的审核，放心用吧。
