Question

我正在寻找一种从PhoneGap和原生Objective-C环境中从iPad获取设备UUID的方法。问题是PhoneGap只给我一个哈希版本的设备UUID。例如：

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

但由于我需要两个值相同，我需要以下解决方案之一 1）如何完全像PhoneGap在Objective-C中那样对[device uniqueIdentifier]进行散列。 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？提前谢谢！

Answer 1

自iOS 5起，

uniqueIdentifier已被弃用。您根本不应再使用它。

Answer 2

由于PhoneGap是开源的，你可以看看它是如何自己生成UUID的。

以下是PhoneGap使用的方法（从1.7.0复制）。我还复制了Apache许可证，以防我应该这样做。

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

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

PhoneGap device.uuid（VS.）iPad [[UIDevice currentDevice] uniqueIdentifier]
