Use the devices Mac address. It's as unique as you could need I think.

blocks|key|371459|text|另一种选择是动态生成您自己的UUID。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|371460|CFUUIDRef+uuid+=+CFUUIDCreate(NULL);+

Another option is dynamically generating your own UUID.

<pre><code>CFUUIDRef uuid = CFUUIDCreate(NULL); 
CFStringRef generatedUuidStr = CFUUIDCreateString(NULL, uuid);
CFRelease(uuid);
NSString* uuidStr = [(NSString*)generatedUuidStr autorelease];
</code></pre>

You could persist this UUID in NSUserDefaults for install based uniqueness. If device based uniqueness is truly the most important thing (so that after an uninstall and reinstall the id persists) you'll need a mechanism to persist the ID on the device. I think you could look into using the Keychain in order to persist that ID which should persist beyond app uninstall. You can even use an access group when adding the UUID to the keychain so that you could have a suite of apps that use the same UUID.

See apple's security framework reference for more info on saving keychain items and retrieving them.

blocks|key|587184|text|使用苹果公司首选的生成CFUUIDRef的方法可能是更好的解决方案，因为我觉得未来可能也会删除MAC地址。如果您使用此应用程序并将其保存到您的NSUserdefaults中，则除非用户删除该应用程序，否则它将保持不变。如果你想要一个生成的唯一ID，你可以在应用程序之间共享，或者在安装之间保存，你应该考虑使用UIPasteboard，并将生成的UID保存为在应用程序之间共享的密钥。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|587185|//Create+a+unique+id+as+a+string

Using Apple's preferred method of generating a CFUUIDRef is probably the better solution as I feel the MAC address may be removed in the future as well. If you use this and save it to your NSUserdefaults you will have it persist unless the user deletes the app. If you want to have a generated unique ID that you can share between apps or persist between installs you should look at using the UIPasteboard and saving your generated UID with a key that you share between apps.

<pre><code>//Create a unique id as a string
CFUUIDRef theUUID = CFUUIDCreate(NULL);
CFStringRef string = CFUUIDCreateString(NULL, theUUID);

//create a new pasteboard with a unique identifier
UIPasteboard *pasteboard = [UIPasteboard pasteboardWithName:@"youruniquestring" create:YES];

[pasteboard setPersistent:YES];

//save the unique identifier string that we created earlier
[pasteboard setString:((__bridge NSString*)string)];


 //accessing it
UIPasteboard *pasteboard = [UIPasteboard pasteboardWithName:@"youruniquestring" create:NO];
NSLog([pasteboard string]);
</code></pre>

I have written a brief tutorial here but its basically the lines above: <a href="http://www.roostersoftstudios.com/2012/03/26/a-way-to-share-data-between-apps-on-a-given-ios-device/">http://www.roostersoftstudios.com/2012/03/26/a-way-to-share-data-between-apps-on-a-given-ios-device/</a>

What is the best way to uniquely register an iOS Device, which won't be limited by future Apple restrictions?

My current approach to register an iOS device (basically to identify the device uniquely) is that I use the UDID of an iOS device to identify it and register it, and then after recognising it I perform the necessary actions.

The issue is that the UIDevice uniqueIdentifier property is deprecated. There are certain workarounds for that (as discussed in <a href="https://stackoverflow.com/questions/6993325/uidevice-uniqueidentifier-deprecated-what-to-do-now">this question</a>) which I'm aware of. 

One possibility is to use the MAC address of an iOS device. However, I feel that Apple may restrict access to this information at some point in the future, as well.

Is there any other way (besides accessing the MAC address) to identify an iOS device, which we can rely on for the future?

What is a long-term method I can use to uniquely identify an iOS device?

什么是唯一注册iOS设备的最佳方式，它不会受到未来苹果限制的限制？我目前注册iOS设备的方法(基本上是唯一地标识设备)是使用iOS设备的UDID来标识它并注册它，然后在识别它之后执行必要的操作。问题是UIDevice uniqueIdentifier属性已被弃用。据我所知，有一些解决方法(如中所述)。一种可能是使用iO...
