ios - iOS 10 中有新的设备标识符吗？

Question

有人在 iOS 10 中找到了唯一标识设备的新方法吗？我没有看到任何文档提到该领域的变化，我想在向供应商标识符投降之前询问一下。

Answer 1

如果您要向商店提交，您留下的唯一真实标识符是 AdSupport 框架的广告标识符。

如果您想进一步深入了解并可能进入一些不安全的 API 领域，您可以连接 IOKit 并尝试获取设备上的电池标识符。这取自 Anthony Agatiello gist UIDevice 扩展:

- (NSString *)batteryID {
    void *IOKit = dlopen("/System/Library/Frameworks/IOKit.framework/Versions/A/IOKit", RTLD_LAZY);
    NSParameterAssert(IOKit);

    mach_port_t *kIOMasterPortDefault = dlsym(IOKit, "kIOMasterPortDefault");
    NSParameterAssert(kIOMasterPortDefault);
    CFMutableDictionaryRef (*IOServiceNameMatching)(const char *name) = dlsym(IOKit, "IOServiceNameMatching");
    NSParameterAssert(IOServiceNameMatching);
    mach_port_t (*IOServiceGetMatchingService)(mach_port_t masterPort, CFDictionaryRef matching) = dlsym(IOKit, "IOServiceGetMatchingService");
    NSParameterAssert(IOServiceGetMatchingService);
    kern_return_t (*IORegistryEntryCreateCFProperties)(mach_port_t entry, CFMutableDictionaryRef *properties, CFAllocatorRef allocator, UInt32 options) = dlsym(IOKit, "IORegistryEntryCreateCFProperties");
    NSParameterAssert(IORegistryEntryCreateCFProperties);
    kern_return_t (*IOObjectRelease)(mach_port_t object) = dlsym(IOKit, "IOObjectRelease");
    NSParameterAssert(IOObjectRelease);

    CFMutableDictionaryRef properties = NULL;

    mach_port_t service = IOServiceGetMatchingService(*kIOMasterPortDefault, IOServiceNameMatching("charger"));
    IORegistryEntryCreateCFProperties(service, &properties, kCFAllocatorDefault, 0);

    IOObjectRelease(service);
    service = 0;

    NSDictionary *dictionary = (__bridge NSDictionary *)properties;
    NSData *batteryIDData = [dictionary objectForKey:@"battery-id"];

    CFRelease(properties);
    properties = NULL;

    dlclose(IOKit);

    return [NSString stringWithUTF8String:[batteryIDData bytes]];
}

这在 iOS 10 上仍然有效。
