我正在寻找一种从 PhoneGap 和本机 Objective-C 环境中的 iPad 获取设备 UUID 的方法。问题是PhoneGap 只给了我设备UUID 的散列版本。例如：

1) device.uuid = E0AB7C8C-EFEE-4EB1-9B8F-A543575390A0
2) [[UIDevice currentDevice] uniqueIdentifier] = 75579DE5-98C7-53B6-B2AD-7F348662CB5D

但是因为我需要两个值相同，所以我需要以下解决方案之一 1）如何像 PhoneGap 在 Objective-C 中一样对 [device uniqueIdentifier] 进行哈希处理。2) 如何从 PhoneGap (JavaScript) 获取原始（非散列）设备的 UUID。

有人知道如何实现这一目标吗？提前致谢！

uniqueIdentifier自 iOS 5 起已弃用。您根本不应该再使用它。

由于 PhoneGap 是开源的，您可以自己查看它是如何生成 UUID 的。

这是 PhoneGap 使用的方法（复制自1.7.0）。我还复制了 Apache 许可证，以防万一。

- (NSString*) uniqueAppInstanceIdentifier
{
    // full path to the app folder
    NSString* bundlePath = [[[NSBundle mainBundle] bundlePath]
        stringByDeletingLastPathComponent];

    // return only the folder name (a GUID)
    return [bundlePath lastPathComponent];
}
