swift - 如何授予 discoverUserInfoWithUserRecordID 权限？

Question

要通过 CloudKit 检索实际登录 iCloud 用户的信息，我需要调用 discoverUserInfoWithUserRecordID 方法。

它的 API 说:

The user must have granted the CKApplicationPermissionUserDiscoverability permission for this container.

它是如何工作的？

Answer 1

swift

CKContainer.defaultContainer().requestApplicationPermission(CKApplicationPermissions.PermissionUserDiscoverability, 
                 completionHandler: {
                      applicationPermissionStatus, error in
                           // check (applicationPermissionStatus == CKApplicationPermissionStatus.Granted)
})

目标-C

[[CKContainer defaultContainer] requestApplicationPermission:CKApplicationPermissionUserDiscoverability
                 completionHandler:^(CKApplicationPermissionStatus applicationPermissionStatus, NSError *error) {
                           // check(applicationPermissionStatus == CKApplicationPermissionStatusGranted)
                 });
}
