我想获取设备ID并将其发送到Web服务。我怎样才能在iOS 6中获得UDID

谢谢

由于安全/隐私原因，iOS 6+不再提供UDID。相反，使用identifierForVendor或advertisingIdentifier。

供应商标识：

An alphanumeric string that uniquely identifies a device to the app’s
vendor. (read-only)

The value of this property is the same for apps that come from the
same vendor running on the same device. A different value is returned
for apps on the same device that come from different vendors, and for
apps on different devices regardless of vendor.

广告识别码：

An alphanumeric string unique to each device, used only for serving
advertisements. (read-only)

Unlike the identifierForVendor property of UIDevice, the same value is
returned to all vendors. This identifier may change—for example, if
the user erases the device—so you should not cache it.

这篇文章解释得很好。
