My iOS Development Status

I have not been back to my iOS development since my Beijing vacation back. May be I am just too lazy or too busy with something else as excuse. One of reasons is that I want to do it in Xcode 4.0 and iOS 5. I got my Xcode updated last month. iOS will be released anytime soon either this month or in October.

Two days before iPad 2 release, today Apple released iOS4.3 for iPhone4 & iPad, as well as massive updates(I wrote a blog today about those items). The most expected XCODE 4.0 is released. I can be purchased from Mac Apple Store at $4.99, unbelievable low price comparing to Microsoft Visual Studio ($799 from MSRP for Professional version to $3,799 for Ultimate). For registered Apple Developers($99 annual fee), it is FREE!

I found a nice open source project for Mac/iOS Address Book data source. The project contains several key wrapper classes: ABContact, ABGroup, and ABContactsHeler. Mac OS/iOS has extensive APIs for accessing and editing AB records, but they are all C libraries. The project provides nice Objective-C wrapper classes for those libraries.

Use iOS Address Book

Recently I have encountered an issue about using iOS Contacts or Apple’s Address Book as data source for my application. The AB provides nice detail data structure for contacts, as well as views and APIs for adding, editing and deleting contacts. The issue is how I build a bridge between the AB contacts and my application.

In my past month, the progress of my iPhone application development has been very slow, almost on hold. There have been too many things happening during the time. A family of my relatives came to my house for visit. That’s the main reason I cannot concentrate on my project. My evenings and weekends have been taken for meals, talks, and sight seeing (we went to Banff for the last weekend, three days).
