获取设备唯一标识

IOS

获取UUID，KeychainAccess中保存的keychain-access-groups为根证书id

const char * Utils::getDeviceId(){    NSBundle *baudel = [NSBundle mainBundle];    NSString  * kcaPath =[baudel pathForResource:@"KeychainAccess" ofType:@"plist"];    NSDictionary * kcad = [NSDictionary dictionaryWithContentsOfFile:kcaPath];    NSArray* kag = [kcad objectForKey:@"keychain-access-groups"];    NSString* kca = [kag objectAtIndex:0];    KeychainItemWrapper *wrapper = [[KeychainItemWrapper alloc] initWithIdentifier:@"UUID" accessGroup:kca];    NSString *struuid = [wrapper objectForKey:(id)kSecValueData];    if (struuid == nil || [struuid isEqualToString:@""])    {        CFUUIDRef pUUID = CFUUIDCreate(nil);        CFStringRef uuidStr = CFUUIDCreateString(nil, pUUID);        NSString *result = (NSString*)CFStringCreateCopy(NULL, uuidStr);        [wrapper setObject:result forKey:(id)kSecValueData];    }    struuid = [wrapper objectForKey:(id)kSecValueData];    [wrapper release];    return [struuid UTF8String];}

其中KeychainAccess.plist为

<?xml version="1.0" encoding="UTF-8"?><!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd"><plist version="1.0"><dict>    <key>get-task-allow</key>    <false/>    <key>keychain-access-groups</key>    <array>        <string>xxxxxxxxx.xxx</string>    </array></dict></plist>

替换xxxxxxxxx.xxx为证书。

安卓

获取android_id

import android.provider.Settings;
String ANDROID_ID = Settings.System.getString(getContentResolver(), Settings.System.ANDROID_ID);

在部分越狱，返厂，以及安卓2.2上可能有问题
