Weibo and iPhone | 新浪微博接口和iPhone SDK 整合

Recently, we have to integrated part of Weibo (新浪微博) features with an App we work for our client. Unfortunately, there isn’t any good resource to help us to communicate between Weibo API & iPhone SDK. Thus, we worked it out by ourselves. We found that it’s feasible to do it using OAuth and JSON library. Followings are the link of these two library:

OAuth for multiple platforms

JSON (Javascript Object Notation) for iPhone

We will talk more about it later!

Again, stay tuned!

Pro Snap 1.5 is sent for approval

Well, I didn’t update this blog for more than a week. I feel very sorry about that. But the reason I leave this blog is we were very busy on the next major update on Pro Snap, which is version 1.5. Compare with 1.0, it’s really powerful this time. We recode some core part of previous version in order to make it runs faster and faster. On the other hand, we add more and more lens filter, which we always focus on making Pro Snap a camera rather than a retouching app like photoshop. So, coming you will have glow filter, motion blur, sepia with improved previous filters. Also, some filter is adjustable right now. =) More and more is coming anyway… Let me upload some latest pic later.

Pro Snap

The coming update of Pro Snap (1.5) is still under development. There will be many features available for the snap shot lovers. I think the most important update is, Pro Snap will provide many customized options for the user to adjust the filters. And if you feel headache about numbers, you can still enjoy the pre-set value that our developer done for you. =)

P.S. We have a plan to do transplant Pro Snap to Android platform. Our experimental team is trying their best to build this tiny thing from the architecture of Pro Snap iPhone. Wish we can announce this good news ASAP!


This is kind of high tech and funny stuff I discovered in engadget, which is a “reversed” version of AR. You just put a model and rotate. The program will compute the 3D model for you!. It’s cool as I can see that there will be cheap 3D scanner for personal use. Hope invivo R&D can make a low-tech version for some flamboyant project. XD


If you are “technomania”, you may know what our work about. Yes, it’s really old and really new. We are putting a legendary arcade into a brand new form, which we make it immerse into the real world. With the help of Augmented  Reality, we make the invaders float into the sky with our real world through the screen of a small device. The similarity is, just like the original game, we can attack the invaders. However, the different is, thanks to the advancement of technology, we can play it with our movement — turning around to find the target and kill them as fast as you can. We find it’s kinda interesting and it’s going to be submitted to Apple for approval soon.
