CKDiscoverAllContactsOperation不提取联系人 [英] CKDiscoverAllContactsOperation not fetching contacts

问题描述

我正在使用 CKDiscoverAllContactsOperation ，但它对我不起作用。

I am using CKDiscoverAllContactsOperation but its not working fine for me.

-(void)queryForAllUsers: (void (^)(NSArray *records))completionHandler {

    CKDiscoverAllContactsOperation *op = [[CKDiscoverAllContactsOperation alloc] init];

    [op setUsesBackgroundSession:YES];
    op.queuePriority = NSOperationQueuePriorityNormal;

    [op setDiscoverAllContactsCompletionBlock:^(NSArray *userInfos, NSError *error) {

        if (error) {
            NSLog(@"An error occured in %@: %@", NSStringFromSelector(_cmd), error);
            //abort();
        } else {

            NSLog(@"Number of records in userInfos is: %ld", (unsigned long)[userInfos count]);
            dispatch_async(dispatch_get_main_queue(), ^(void){
                completionHandler(userInfos);
            });
        }
    }];
    [self.container addOperation:op];
}

我正在使用的容器是 publicCloudDatabase 。

The container which I'm using is publicCloudDatabase.

推荐答案

搜索仅在不同用户激活应用程序，被批准为可发现并且其他人拥有iCloud电子邮件地址时才有效联系方式。

The search only works if different users activate the app, approved to be Discoverable and have the other person's iCloud email address in their Contacts.
