Spent almost the whole day working on assignment 4 part 1. Had to work with many static data, which means lots of hardcoding. Doesn't feel right to me. Still, managed to learn more things. Played around with the UINavigationController and UITabBarController. It all seemed so confusing at first. The moment I started to work on the program, somehow it all became clear. I was able to understand the way these controllers work.
Found out that there are some properties to identify the controls that we put in the interface builder. We needed the unique identifiers in order to work with the controls, since we are not making use of IBOutlets in this assignment.
Encountered the problem of losing my array of images. All along, I set the property of my instance variable to 'assign', and somehow, the array gets missing later on when I want to access it. Then, I decided to change it to 'copy', and the problem was gone. A lesson learnt! Gonna ask Kevin more about this on Monday.
We were also invited to the GM group's meeting. A colleague, Gim Han, presented on how he went about reconstructing contour lines drawn by doctors and present them in 3D. He talked about his algorithms and explained why he was taking a particular approach. Kinda amazed throughout the whole presentation. The stuff he talked about were so foreign to me. I really wonder how long it took he to come up with all those algorithms. All the staff in the meeting room were very helpful, providing constructive feedback. I can actually see the teamwork there when they helped one another to clarify their doubts.
