多版本对象权限

NSString *endPoint = @"your-endpoint";
// 认证用的ak和sk硬编码到代码中或者明文存储都有很大的安全风险，建议在配置文件或者环境变量中密文存放，使用时解密，确保安全；本示例以ak和sk保存在环境变量中为例，运行本示例前请先在本地环境中设置环境变量AccessKeyID和SecretAccessKey。

NSString *AK = [NSString stringWithUTF8String:ak_env];
NSString *SK = [NSString stringWithUTF8String:sk_env];
    
// 初始化身份验证

OBSUser *owner = [[OBSUser alloc] initWithID:@"249e6c2bfbc74c928d5893895543029e"];
    
OBSACLGranteeUser *grantee = [[OBSACLGranteeUser alloc]initWithID:@"AKjdsjklSKLL/DSKDSLADLADLjdsjald231124"];
// 为授权用户设置所有权限
OBSACLGrant *grant = [[OBSACLGrant alloc]initWithGrantee:grantee permission:OBSACLFull_Control];

policy.owner = owner;
[policy.accessControlList addObject:grant];

    [policy.accessControlList addObject:grant];
 }

[client setObjectACL:request completionHandler:^(OBSSetObjectACLResponse *response, NSError *error){
    NSLog(@"%@",response);
}];

ACL中需要填写的所有者（Owner）或者被授权用户（Grantee）的ID，是指用户的账号ID，可通过OBS控制台“我的凭证”页面查看。
