What is the basic difference between NSTimer, NSTask, NSThread and NSRunloop?

http://stackoverflow.com/questions/1124207/what-is-the-basic-difference-between-nstimer-nstask-nsthread-and-nsrunloop

its own run loop and you very rarely have to concern yourself with them directly. The run loop is also in charge of creating and releasing autorelease pools. EDIT See comments for more discussion about autorelease pools. The most important point.. it keeps the interface reactive. That's why you should never run code that's time consuming on the main thread it will eat up all time on the thread and the run loop will not be allowed to run often enough resulting in a locked or slow interface... interface. If you need to perform time consuming calculations or keep a task running in the background you should create a new thread. Again you probably don't have to think about the new run loop being created. An easy way of performing a..

Understanding the memory consumption on iPhone

http://stackoverflow.com/questions/363493/understanding-the-memory-consumption-on-iphone

where exactly the memory goes. The Object Alloc tool is almost useless for tracking the real memory usage. When I create a texture the allocated memory counter goes up for a while reading the texture into the memory then drops passing the texture.. in memory to be used. Every pixel takes up four bytes so forgetting to release your texture image data can really eat up your memory quickly. Second it is possible to debug texture memory with Instruments. There are two profiling configurations.. this will obviously cause this problem. Ensure your'e not accessing autoreleased memory common cause of crashes. Create a separate test app and play with loading textures individually and in combination to find out what texture or combination..
