Ok...... I'm implementing a simple OpenGL ES application on the iPhone and I recently added in Pinch Media Analytics. Doing this helped uncover a memory management problem, and I'm not entirely sure how to deal with it. In a perfect world, my application - which loads PNGs and .CAF files in didFinishLoading will launch, load all of it...
In one of my builds for an iPhone app, I had inadvertently created a variable that shadowed a variable in the scope above it. This was unintentional, but compiled since Objective-C apparently allows shadowing of variables between an if block and its containing method. When I sent out this code, people that were using iPhone 3Gs immedia...
Ok, I've read the articles about why it's a better idea to use an NSRunLoop instead of an NSTimer call to run a game loop and maintain a nice frame rate. But what I haven't seen in any of the discussions is where to create the NSRunLoop. Should that be put at the end of didFinishLoading? ...

I can use the simulator fi...

Hi all, I was just recently futzing about with a sample application trying to get my head completely wrapped around NSRunLoop. The sample I wrote created a simple secondary thread via NSOperation. The secondary thread does a few tasks such as process an NSTimer and also some rudimentary streaming with NSStream. Both of these input sourc...
