Pitfalls of NSFetchedResultsController

I have recently used one of the most useful framework in iPhone 3.0 – CoreData.

There are many guides on using CoreData, such as from cocoadevcentral or Apple’s guide. But what I found lacking is that there was no discussion on the pitfalls of using CoreData, or its view controller, NSFetchedResultsController.

I learnt the pitfalls along the way, and there are 3 particular pitfalls that I would like to share with developers while developing txeet for iPhone.

Apple says txeet should be rated 17+

Apple’s appreview team reviewed txeet and deemed that it should be rated 17+, as it contains adult theme. They sent me a screenshot of the app:

Okay.. there are adult jokes and vulgarity in some of the templates.. but they are funny and interesting :)

txeet has been submitted to iTunes

After 3 months of porting txeet from Android to iPhone, the work is completed at last!

The good news is that txeet on iPhone is as good (if not better) as that on Android. In terms of feature, they are the same.

Below is a preview of the iPhone app. It looks cooler (than Android), imo (:

A lot of lessons were learnt in the development of the iPhone app. I would be sharing some valuable lessons in the use of iPhone’s CoreData in the coming days.

A lot of work was put into beautifying the app too. You might have notice the new txeet icon used.

For now, let’s pray that Apple review team can approve the app quickly, so that it will be in time for Valentine’s Day!
