What is the right way of using kKCSAll? I am using it like this and the program crashes:



KCSQuery *findSenders = [KCSQuery queryOnField:@"recipients._id"

usingConditional:kKCSAll forValue:@[[KCSUser activeUser].userId]];

KCSCollection* collection = [KCSCollection collectionFromString:@"inbox" ofClass:[TSSMessage class]];

KCSLinkedAppdataStore* store = [KCSLinkedAppdataStore storeWithOptions:@{KCSStoreKeyResource: collection,

KCSStoreKeyCachePolicy: @(KCSCachePolicyNetworkFirst)}];



[store queryWithQuery:findSenders withCompletionBlock:^(NSArray *objectsOrNil, NSError *errorOrNil) {

if (objectsOrNil)

self.senderList = objectsOrNil;

else

[self refreshFailed:errorOrNil.description];

} withProgressBlock:nil];

You probably want to use queryOnField:withExactMatchForValue: instead.

I have a list of users in "recipients" field. I want to find the records that has specific user/usres in recipients field. How should I do that?

queryOnField:withExactMatchForValue works for on value. But how can match the field with a last of values?

I am not sure what you mean, can you give an example of exactly what you want to load?

Suppose I want all the users that sent a message to user1 and user2. I thought this should do it



KCSQuery findSenders = [KCSQuery queryOnField:@"recipients._id" usingConditional:kKCSAll forValue:@[user1.userId, user2.userId]];

Does it have to match both user1 and user2 or does it match user1 OR user2?

I have use case for both.

Hi Ali, Are you still stuck?

Well, I still don't know how to match an array of values

Hi Ali, We'd really like to help, we're just having trouble trying to figure out exactly what you're trying to do and where you're getting stuck. Can you give us some background on the use case? Also, are you on the latest SDK version?

That's ok Caroline, I changed the way I handle it and I am not using kKCSAll any more, but as I mentioned earlier suppose I want to find all of the events that some user sent some other users an egg. Suppose recipients is an array of users that received an egg in each event, Then for example this should find all of events that in those an egg is sent to user1 and user2:



KCSQuery findEvents = [KCSQuery queryOnField:@"recipients._id" usingConditional:kKCSAll forValue:@[user1.userId, user2.userId]];
