Hi, awhile back I asked for basic programming ideas to challenge myself in objective-C, a language that i am not very advanced in. One idea that was suggested was Conways game of Life found here... http://en.wikipedia.org/wiki/Conway's_Game_of_Life I was very interested in this challenge and have sat down many times over the last few weeks trying to make such a program in xcode 3, using objective-C. So far I have been unsuccessful and need some help. 1.) What is best to use as a "cell". I was thinking a square button or picture view. 2.) What method should i use to detect the neighboring cells If anyone has any suggestions it would greatly appreciated. Also i cant seem to find this program for mac except on java, which i am not that good at, so if anyone knows where to find this program already made with non-java source code, u could point me to that. Thanks in advance.
