Ios URLForUbiquityContainerIdentifier为有效的、容器ID的权利返回零

我不能让URLForUbiquityContainerIdentifier在iOS上为我的iCloud容器工作。我有：

已将iCloud容器添加到开发者门户上的应用程序和资源调配配置文件中

设置iCloud权限，包括Xcode中的容器

已验证已签名应用程序包中的团队ID和权限：

使用查询文档路径：

    NSString *teamID = @"8KJB799CU7"; // replace with your real Team ID
    NSString *bundleID = @"iCloud.com.vedanamedia.familydiagram";
    NSString *containerID = [NSString stringWithFormat:@"%@.%@", teamID, bundleID];
    NSURL *_iCloudRoot = [[NSFileManager defaultManager] URLForUbiquityContainerIdentifier:containerID];

---

似乎什么都不管用，iCloudRoot总是零。还有什么我可以查的吗？我已经讨论了几个小时。

即使文档状态将TEAMID.CONTAINER作为urlforubiquitycontainerinidentifier传递给指定容器，我还是成功地传递了容器的绑定标识符
