get UDID of IOS device programmatically?
我想以编程方式获取iOS设备的udid。我使用以下代码获取iOS设备的UDID。
1 2 | NSUUID *uuid = [NSUUID UUID]; NSString *uuidString = uuid.UUIDString; |
但我得到的输出和我设备的实际UDID不同。
1 2 | NSString* identifier = [[[UIDevice currentDevice] identifierForVendor] UUIDString]; // IOS 6+ NSLog(@"output is : %@", identifier); |

1 2 | let identifier: String = UIDevice.currentDevice().identifierForVendor().UUIDString() NSLog("output is : %@", identifier) |

1 2 3 | let identifier = UIDevice.current.identifierForVendor?.uuidString NSLog("output is : %@", identifier! as String) |

Apple is apparently starting to remove access to the UDID (Unique Device IDentifier) in iOS5. In any event, the best you can now do for identification purposes is to use a UUID (Universally Unique IDentifier). This has to be on a per-app basis. That is, there is no way to identify the device any longer, but you can identify an app on a device.As long as the user doesn’t completely delete the app, then this identifier will persist between app launches, and at least let you identify the same user using a particular app on a device. Unfortunately, if the user completely deletes and then reinstalls the app then the ID will change, but this is the best anyone can do going forward.
