I have started working on a new Xcode project, a game to be exact. Now, i will be adding what you might call sprites to the screen quite frequently, and the image that represents them will be either of a total of 3. Now, when i start adding these images programmatically to the viewcontrollers view, the app will start lagging as i reach a still fairly low number compared to many other games out there (maybe 5-10). Now, i was wondering if it had to do with caching? i see you can cache images in Cocos2d which i just started learning, to reduce the processing time of rendering the images on-screen. How do i come about this in Xcode?

IN SHORT: How do i “cache” or allow Xcode to rapidly draw images to prevent lag when drawing multiple images?

Thanks on advance.

    Xcode is the IDE and development environment, it’s not the operating system, which is where any caching would really be happening.

    UIImage does do some kind of caching (here is a related question that talks about this) but if you’re going to be using cocos2d, you should rely more upon whatever your game framework provides versus what the O.S> provides.
