Harish, 


We have a guide that goes over how to do this on a query-level available here:  http://devcenter.kinvey.com/ios/guides/datastore#modifiers .   


The code to handle the front-end pagination on iOS, is less trivial, and beyond the scope of what we can reasonably help with. 


Please let me know if you have any additional questions.


Thanks,




Harish:  


Yes we do support pagination:  ?query.....&limit=100&skip=100  where limit is the number per page and skip is what you increment when calling additional pages.


Thanks,

Hi Damien Bell,


Im writing pice of code like this by using limit modifiers, can u check it once whether is it correct or not.


KCSQuery *query = [KCSQuery queryOnField:@"ccu_id" withExactMatchForValue:@"c331dce3bced562b"];

 

 query.limitModifer = [[KCSQueryLimitModifier alloc] initWithLimit:20];

 

 query.skipModifier = [[KCSQuerySkipModifier alloc] initWithcount:20];

 

 KCSQuery *combinedQuery = [KCSQuery queryForJoiningOperator:kKCSAnd onQueries:query, nil];

 

 [_alertCollectionStore queryWithQuery:combinedQuery

 withCompletionBlock:^(NSArray *objectsOrNil, NSError *errorOrNil) {


}
