ios – 或使用include查询

我有一个连接表,其中包含from列和a列.两列都指向用户对象.执行此OR查询时,它会抛出错误：’OR查询不支持包含’的子查询’

有没有办法解决？谢谢！

//设置查询以获取当前用户与其他用户联系的所有关系.

PFQuery *userIsFriendSender = [PFQuery queryWithClassName:@"UserRelationships"];
[userIsFriendSender whereKey:@"from" equalTo:[PFUser currentUser]];
[userIsFriendSender whereKey:@"active" equalTo:@YES];

[userIsFriendSender includeKey:@"to"];

// set up query to get all relationships where a use friended the current user
PFQuery *userIsFriendReceiver = [PFQuery queryWithClassName:@"UserRelationships"];
[userIsFriendReceiver whereKey:@"to" equalTo:[PFUser currentUser]];
[userIsFriendReceiver whereKey:@"active" equalTo:@YES];

[userIsFriendReceiver includeKey:@"from"];

PFQuery *query = [PFQuery orQueryWithSubqueries:@[userIsFriendSender,userIsFriendReceiver]];

解决方法

尝试将includeKey：子句移动到联合查询.

PFQuery *query = [PFQuery orQueryWithSubqueries:@[userIsFriendSender,userIsFriendReceiver]];
[query includeKey:@"from"];
[query includeKey:@"to"];
