• uniqueIdentifier在ios7不支持后的替代方法


    UIDevice的uniqueIdentifier方法在ios7就不支持了, 为了获得设备相关唯一标识符
    参考了这里:
    https://github.com/Itayber/UIDevice-uniqueID

    但是改了部分代码(下面会贴上代码). 另外,真机编译会出问题,解决记录如下:
    1.  把我修改了的UIDevice-uniqueID.h/m(见下面代码)加到工程里.
    2.  加IOKit.framework:
    把IOKit.framework(在/Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS6.0.sdk/System/Library/Frameworks/IOKit.framework) 拖到 编译选项-Build Phases-Link Binary With Libraries里.(注意到这个framework里没有头文件...)
    3.  加IOKit的头文件:
        在工程目录下的源文件目录里新建IOKit文件夹,
    把/Applications/Xcode.app/Contents/Developer/Platforms/iPhoneSimulator.platform/Developer/SDKs/iPhoneSimulator6.0.sdk/System/Library/Frameworks/IOKit.framework/Headers里的文件都拷贝到该目录里.
        同时添加好头文件搜索路径:
        在编译选项-Build Settings-Header Search Paths添加$SRCROOT,并且可递归遍历:recursive.
    4. done.

    注意这个方法虽然算出了设备相关的唯一标识符,但其结果和原uniqueIdentifier函数结果是不一样的,且如果上appStore很有可能会被苹果审核为不通过.
