by Roman in Mobile Programming

I am trying to figure out how to write the following SQL in the form of the Core Data fetch statements:


select count(*) from MYTABLE where MYTABLE.size='2';

//setup predicate
NSPredicate *predicate = [NSPredicate predicateWithFormat:@"ANY %K == %@", @"size", searchInteger];

Core-Data: Fetch objects from 3 entities into one fetch and sort by date?
by ti22 in Operating Systems

I could use some help breaking down this puzzle.


1) I want to fetch objects from 3 entities ('A','B','C') in Core-Data (they all have different data types, except 'date') - have them in one big fetch, somehow? Should they have relations to a new entity 'D' or?


2) Later, I want to sort the big fetch by date (but I dont think it's an issue for me if I have the whole fetch)


git fetch vs. git fetch origin master have different effects on tracking branch
by johntynan in Programming Languages

This is mostly of the nature of a curiosity as I'm trying to get familiar with Git. I have looked at the documentation for 'git fetch' but I don't see an obvious explanation for the below. Thanks in advance, and apologies if this is howlingly obvious.


1) From a central repository, say GitHub, I clone a repository named 'website' on each of two machines, HostA

A fetch request can only fetch one entity at a time, right?
by Max Derov in Mobile Programming

Is that true? Or could I fetch multiple entities at once? If so, how would that look like?


(Guess: No. NSFetchRequest asks for one and only one entity)

I am fetching the collection from server once the save is complete. But as fetch is async the view is rendering before fetch is complete
by Michael in Programming Languages

I am calling a fetch on a collection and inside its success methods fetching another collection. Once its done I am adding both the collections and rendering to the view. After I save a new item in the view, it saves in the db and after save is complete I am calling the methods that does fetching. All I want to do is to render the updated collection which now should include a newly crated model
