Unity功能记录(二十) ------ 获取Android与ios唯一设备标识码UUID

            Android功能记录(一) ------ 获取手机唯一标识码

以下方法对于华为手机无效

---

被坑的好狠~

原本以为SystemInfo.deviceUniqueIdentifier就是设备唯一标识码,谁知道,这个在某些设备上获取的是动态变化的!!!!?

一.Android

  /**
     * 返回 唯一的虚拟 ID
     * @return ID
     */
    public void getUniquePsuedoID() {
        String m_szDevIDShort = "35" + (Build.BOARD.length() % 10) + (Build.BRAND.length() % 10) + (Build.CPU_ABI.length() % 10) + (Build.DEVICE.length() % 10) + (Build.MANUFACTURER.length() % 10) + (Build.MODEL.length() % 10) + (Build.PRODUCT.length() % 10);

        // API >= 9 的设备才有 android.os.Build.SERIAL
        // http://developer.android.com/reference/android/os/Build.html#SERIAL
        // 如果用户更新了系统或 root 了他们的设备，该 API 将会产生重复记录
        String serial = null;
        try {
            serial = android.os.Build.class.getField("SERIAL").get(null).toString();
            UnityPlayer.UnitySendMessage("ScriptHolder","GetUUID",new UUID(m_szDevIDShort.hashCode(), serial.hashCode()).toString());
            return;
        } catch (Exception exception) {
            serial = "serial";
        }

        // 最后，组合上述值并生成 UUID 作为唯一 ID
        UnityPlayer.UnitySendMessage("ScriptHolder","GetUUID",new UUID(m_szDevIDShort.hashCode(), serial.hashCode()).toString());
    }

调用 :

 playerActivity = new AndroidJavaClass("com.unity3d.player.UnityPlayer");
        jo = playerActivity.GetStatic("currentActivity");
        jo.Call("getUniquePsuedoID");

二.iOS

UUIDTool.h:

#import 

@interface UUIDTool : NSObject

/**
 * 普通的获取UUID的方法
 */
+ (NSString *)getUUID;

/**
 * 获取到UUID后存入系统中的keychain中，保证以后每次可以得到相同的唯一标志
 * 不用添加plist文件，当程序删除后重装，仍可以得到相同的唯一标示
 * 但是当系统升级或者刷机后，系统中的钥匙串会被清空，再次获取的UUID会与之前的不同
 * @return keychain中存储的UUID
 */
+ (NSString *)getUUIDInKeychain;

/**
 * 删除存储在keychain中的UUID
 * 如果删除后，重新获取用户的UUID会与之前的UUID不同
 */
+ (void)deleteKeyChain;


@end

#import "UUIDTool.h"

NSString * const kUUIDKey = @"com.myApp.uuid";

@implementation UUIDTool

// 普通的获取UUID的方法
+ (NSString *)getUUID {
    CFUUIDRef puuid = CFUUIDCreate( nil );
    CFStringRef uuidString = CFUUIDCreateString(nil, puuid);
    NSString *result = (NSString *)CFBridgingRelease(CFStringCreateCopy( NULL, uuidString));
    return result;
}


#pragma mark - 获取到UUID后存入系统中的keychain中

+ (NSString *)getUUIDInKeychain {
    // 1.直接从keychain中获取UUID
    NSString *getUDIDInKeychain = (NSString *)[UUIDTool load:kUUIDKey];
    NSLog(@"从keychain中获取UUID%@", getUDIDInKeychain);
    
    // 2.如果获取不到，需要生成UUID并存入系统中的keychain
    if (!getUDIDInKeychain || [getUDIDInKeychain isEqualToString:@""] || [getUDIDInKeychain isKindOfClass:[NSNull class]]) {
        // 2.1 生成UUID
        CFUUIDRef puuid = CFUUIDCreate(nil);
        CFStringRef uuidString = CFUUIDCreateString(nil, puuid);
        NSString *result = (NSString *)CFBridgingRelease(CFStringCreateCopy(NULL, uuidString));
        CFRelease(puuid);
        CFRelease(uuidString);
        NSLog(@"生成UUID：%@",result);
        // 2.2 将生成的UUID保存到keychain中
        [UUIDTool save:kUUIDKey data:result];
        // 2.3 从keychain中获取UUID
        getUDIDInKeychain = (NSString *)[UUIDTool load:kUUIDKey];
    }
    
    return getUDIDInKeychain;
}


#pragma mark - 删除存储在keychain中的UUID

+ (void)deleteKeyChain {
    [self delete:kUUIDKey];
}


#pragma mark - 私有方法

+ (NSMutableDictionary *)getKeyChainQuery:(NSString *)service {
    return [NSMutableDictionary dictionaryWithObjectsAndKeys:(id)kSecClassGenericPassword,(id)kSecClass,service,(id)kSecAttrService,service,(id)kSecAttrAccount,(id)kSecAttrAccessibleAfterFirstUnlock,(id)kSecAttrAccessible, nil];
}

// 从keychain中获取UUID
+ (id)load:(NSString *)service {
    id ret = nil;
    NSMutableDictionary *keychainQuery = [self getKeyChainQuery:service];
    [keychainQuery setObject:(id)kCFBooleanTrue forKey:(id)kSecReturnData];
    [keychainQuery setObject:(id)kSecMatchLimitOne forKey:(id)kSecMatchLimit];
    CFDataRef keyData = NULL;
    if (SecItemCopyMatching((CFDictionaryRef)keychainQuery, (CFTypeRef *)&keyData) == noErr) {
        @try {
            ret = [NSKeyedUnarchiver unarchiveObjectWithData:(__bridge NSData *)keyData];
        }
        @catch (NSException *exception) {
            NSLog(@"Unarchive of %@ failed: %@", service, exception);
        }
        @finally {
            NSLog(@"finally");
        }
    }
    
    if (keyData) {
        CFRelease(keyData);
    }
    NSLog(@"ret = %@", ret);
    return ret;
}

+ (void)delete:(NSString *)service {
    NSMutableDictionary *keychainQuery = [self getKeyChainQuery:service];
    SecItemDelete((CFDictionaryRef)keychainQuery);
}

// 将生成的UUID保存到keychain中
+ (void)save:(NSString *)service data:(id)data {
    // Get search dictionary
    NSMutableDictionary *keychainQuery = [self getKeyChainQuery:service];
    // Delete old item before add new item
    SecItemDelete((CFDictionaryRef)keychainQuery);
    // Add new object to search dictionary(Attention:the data format)
    [keychainQuery setObject:[NSKeyedArchiver archivedDataWithRootObject:data] forKey:(id)kSecValueData];
    // Add item to keychain with the search dictionary
    SecItemAdd((CFDictionaryRef)keychainQuery, NULL);
}


@end
#if defined (__cplusplus)
extern "C" {
#endif

void _getUUIDInKeychain()
{
    NSString *s = [UUIDTool getUUIDInKeychain];
    UnitySendMessage("ScriptHolder","GetUUID",s.UTF8String);
}

# if defined (__cplusplus)
}
#endif

Unity UUIDToolExtern.cs :

using System.Collections;
using System.Collections.Generic;
using System.Runtime.InteropServices;

public class UUIDToolExtern
{
#if UNITY_IOS && !UNITY_EDITOR
    [DllImport("__Internal")]
    private static extern void _getUUIDInKeychain();
    public static void getUUIDInKeychain()
    {
        _getUUIDInKeychain();
    }
#endif

}

注意xcode打包时要注意以下设置:

 

三.unity调用

Android调用 :
#if UNITY_ANDROID && !UNITY_EDITOR
        playerActivity = new AndroidJavaClass("com.unity3d.player.UnityPlayer");
        jo = playerActivity.GetStatic("currentActivity");
        jo.Call("getUniquePsuedoID");
#endif

iOS调用:
#if UNITY_IOS && !UNITY_EDITOR
          UUIDToolExtern.getUUIDInKeychain();
#endif

 

最后请注意 :

Android和iOS回调回来的第一个参数自己要修改,否则是不会回调到你的函数的
