unity iOS获取UUID

1.unity 新建UUIDToolExtern.cs
[DllImport("__Internal")] private static extern string _getUUIDInKeychain(); public static string getUUIDInKeychain() {    return _getUUIDInKeychain(); }
2.ios 新建 UUIDTool.h
////  UUIDTool.h//  Unity-iPhone////  Created by zhangyu on 2022/6/7.//#import <Foundation/Foundation.h> @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
3.ios 新建UUIDTool.m

4.需要特别设置iOS
