[Programming] Learning OpenGL ES for iPhone Application development

This week, after completing our first application, I was given permission to explore and learn openGL ES for iPhone Application Development. This has been a great week and I have come across various forums and tutorial sites. I am thinking to keep my blog updated with all the steps I am taking in exploring graphics programming in iPhone. So here is the first post. I came across this blog post via iPhoneDevelopmentBits. The post is very resourceful and the first link I visited is iPhone OpenGL ES Series.

This post is for those, who don’t know where to start graphics programming in iPhone.

Happy iPhone Coding

[Programming] Program exited with status value 101

My application had a UITableView with about more than 250 rows and when I scrolled through it completely twice or thrice; the application CRASHED and a line appeared at my application’s status bar that ”Program exited with status value: 101″. I ran the application in Leaks tool from Instruments option in XCode. It did not show any leaks, but then again application crashed and I received same message on my status bar of application, i.e. ”Program exited with status value: 101″.

After a lot of googling, I found that status 101 indicates that there is a memory issue; meaning that no more memory was available for the application. The application did not crash because of any memory leak, but it crashed due to too much memory allocations…sounds logical. So I optimized my code of populating the cells and voila, the application lived happily ever after and did not crash

One of my previous post “The Stories Behind Hollywood Studio Logos” around 13 months back has brought the most traffic to my blog. A simple (not so complex) observation on my blog visiting statistics, I have decided to post some useful stuff on my blog……. which might help anyone anywhere. So my new year resolution will be to modify my blog and make it useful for everyone. As an initial step, I’ll share here my top 10 posts, which have brought the most traffic to my blog. I will be removing some unnecessary posts from my blog. I hope this might not effect anyone
