What would be a better/good approach of downloading and complex object and storing it into core data efficiently?

And why do I get a moderator message for being rude? In what way I am being rude? I am not the only one asking for sample codes for common problems.

http://stackoverflow.com/search?q=sample+code

What's the difference between that particular question and all other questions ?

Thats really not a question –  Lucifer Oct 4 '12 at 1:56
    
I am asking for some code sample. Where can I find those? I think I asked similar questions before. What I am missing. I am really missing what the problem is. I am not trying to be sarcastic or anything. –  Jim Thio Oct 4 '12 at 1:58

Maybe I should add a few code samples of what I am currently doing. Looks to me all stackoverflow questions need to contain code. –  Jim Thio Oct 4 '12 at 1:59

yes, that is nice way to ask, otherwise someone will only think that you want readymade code, and you haven't done any searching for it. –  Lucifer Oct 4 '12 at 2:04
    
So that's the issue. I see. I see. –  Jim Thio Oct 4 '12 at 2:08

No, questions don't have to include code. Questions DO need to ask a clear question that is not just "give me the code". Why, for instance, did the links to informational videos not solve your problem? The fact that you insist on being provided with pre-written code looks fishy. –  Ben D Oct 4 '12 at 2:09
    
Because it's a very common problem and I've searched everywhere and couldn't find a solution. My own solution is fishy. –  Jim Thio Oct 4 '12 at 2:32
    
Edit your question to ask for approach rather than code. –  nhahtdh Oct 4 '12 at 2:43

As I mentioned in the comment thread of the question, Stack Overflow does not exist to spit out code snippets for you. Try something. Put forth something that resembles effort. Or hire a competent developer to write the code for you. –  Jack Maney Oct 4 '12 at 2:44
    
I already tried something and will post that. Yea approach would be better. Thanks for all the suggestion. –  Jim Thio Oct 4 '12 at 2:52
    
Look if asking for sample code is off topic then just say so. –  Jim Thio Oct 4 '12 at 3:14

@JimThio - Pointing out that other people are also asking questions equivalent to "gimmeh teh codez, plz" is irrelevant. Again, it is not our job to vomit out code snippets for you. Hire a competent developer. –  Jack Maney Oct 4 '12 at 3:18
    
I am asking a question what's the difference between all those questions asking for sample code from my question. That is a very SIMPLE question. Why keep circumventing. –  Jim Thio Oct 4 '12 at 3:23
    
@JimThio - Again, the fact that other people have begged for code snippets is utterly and completely irrelevant. This question remains unacceptable in SO. Period. End of story. End of debate. –  Jack Maney Oct 4 '12 at 3:32

Where can I see sample codes of downloading and complex object and storing it into core data efficiently?

Because a question asking for code samples is not acceptable here.

In general, Stack Overflow questions should not have answers where there is no objective criteria for deciding if it is correct or not. If I answer a question, I should have the right to know that my answer is actually answering the question, not guessing at an answer. If the only person who can decide if an answer is right is the OP, then it's probably not a good question.

In your case, you just want some random ObjectiveC code about dealing with "complex object"s. Who's to say that one bit of such code is any better than another? It would be nothing more than a popularity contest between various different schemes for such things.

That's not what Stack Overflow is for. I shouldn't have to guess if a particular answer is "complex" enough for you, or shows off exactly what you need or whatever.

Look if asking for sample code is off topic then just say so.

It's not a matter of on-topic vs. off-topic. It's a matter of what is appropriate for what we do here. And your question is not.

stackoverflow.com/search?q=sample+code there are many others that also ask for sample codes. The criteria is simply efficient (not going to the permanent store too often, with prefetching. –  Jim Thio Oct 4 '12 at 3:18

@Jim: Questions from 2010 are old. Once upon a time, we tolerated garbage questions like that. We're more strict about question standards than we used to be. If you look at more recent stuff, you'll see more downvoting of such questions. Also, old questions with downvotes and no answers generally are culled by the system, so looking into the history will only show the ones that were tolerated, not eliminated. –  Nicol Bolas Oct 4 '12 at 3:23

I see. That is A GOOD answer to my question. That's it. That's all I ask. –  Jim Thio Oct 4 '12 at 3:30
    
And I have found the answer to the question. I updated the question. It's actually a very easy question for those who are knowledgeable. –  Jim Thio Oct 4 '12 at 7:49

@JimThio - In its original state, it was not an easy question, even for those experienced with the topic. I work with Core Data all the time (I even taught a class on it) and I couldn't follow what you were asking in your original version. Only after you had edited for clarity and provided the sample code that you did was I able to understand your problem. It wasn't a matter of domain expertise, but one of how the problem was presented. –  Brad Larson Oct 4 '12 at 15:11
    
I deleted the original question already. –  Jim Thio Oct 6 '12 at 11:18
    
stackoverflow.com/questions/1172413/… solve my problem perfectly by the way :D LOL –  Jim Thio Oct 7 '12 at 12:17
