如果有人在寻找替代方案时偶然发现了这个问题。我在IDManager课上就采用了这种方法， 这是不同解的集合。KeyChainUtil是一个从keychain读取的包装器。 您还可以使用散列MAC地址作为一种唯一ID。

}

我也遇到了一些问题，解决方法很简单:

    // Get Bundle Info for Remote Registration (handy if you have more than one app)
    NSString *appName = [[[NSBundle mainBundle] infoDictionary] objectForKey:@"CFBundleDisplayName"];
    NSString *appVersion = [[[NSBundle mainBundle] infoDictionary] objectForKey:@"CFBundleVersion"];


    // Get the users Device Model, Display Name, Unique ID, Token & Version Number
    UIDevice *dev = [UIDevice currentDevice];
    NSString *deviceUuid=[dev.identifierForVendor  UUIDString];

    NSString *deviceName = dev.name;

你可以通过以下代码实现:uidevice -with- uniqueidentifier -for ios -5

您可能想要考虑使用OpenUDID，它是已弃用UDID的临时替代品。

基本上，要匹配UDID，需要以下特性:

唯一的或足够唯一的(低概率碰撞是 可能是可以接受的) 跨重启、恢复、卸载的持久性 在不同供应商的应用程序中可用(通过CPI网络获取用户很有用)-

OpenUDID实现了上述功能，甚至有一个内置的选择退出机制供以后考虑。

检查http://OpenUDID.org，它指向相应的GitHub。 希望这能有所帮助!

作为旁注，我将回避任何MAC地址的替代方案。虽然MAC地址似乎是一种诱人的通用解决方案，但要确保这个唾手可得的果实是有毒的。MAC地址是非常敏感的，在你说“提交这个应用程序”之前，苹果可能会非常反对访问这个地址……MAC网络地址用于对wlan (private lan)或其他vpn (virtual private network)中的某些设备进行认证。它甚至比以前的UDID更敏感!

+ (NSString *) getUniqueUUID {
    NSError * error;
    NSString * uuid = [KeychainUtils getPasswordForUsername:kBuyassUser andServiceName:kIdOgBetilngService error:&error];
    if (error) {
    NSLog(@"Error geting unique UUID for this device! %@", [error localizedDescription]);
    return nil;
    }
    if (!uuid) {
        DLog(@"No UUID found. Creating a new one.");
        uuid = [IDManager GetUUID];
        uuid = [Util md5String:uuid];
        [KeychainUtils storeUsername:USER_NAME andPassword:uuid forServiceName:SERVICE_NAME updateExisting:YES error:&error];
        if (error) {
            NSLog(@"Error getting unique UUID for this device! %@", [error localizedDescription]);
            return nil;
        }
    }
    return uuid;
}

iOS 6中引入的UIDevice identifierForVendor可以满足你的需求。

identifierForVendor是一个字母数字字符串，用于唯一标识应用程序供应商的设备。(只读)

@property(nonatomic, readonly, retain) NSUUID *identifierForVendor

对于运行在同一设备上的来自同一供应商的应用程序，此属性的值是相同的。对于同一设备上来自不同供应商的应用程序返回不同的值，对于不同设备上的应用程序返回不同的值，与供应商无关。

在iOS 6.0及更高版本中可用，在UIDevice.h中声明

对于iOS 5，请参考此链接UIDevice-with-UniqueIdentifier-for-iOS-5
