Not every object needs to be released. You should revise the memory management guidelines, this a comprehensive guide about memory management.

The gist of it is: if you obtained an object from a method with the word alloc, new or copy in its name, then you need to release it. You also need to balance each retain with a release or autorelease.

release only reduces an objects retain count, it does not necessarily deallocate it from memory. It is only deallocated when its retain count reaches 0.

Objects are not necessarily cleared from memory when you call release. Also, it might be necessary to call special functions for Core Foundation objects (such as CGColorRef). In general, you have to call one release or autorelease for every alloc, retain or copy call you make on an object.

For more details, see Apple's memory management guide.
