Put simply. Imagine you have some class buried in your code that needs a few simple config values to do its job. That means everything that creates an instance of that class needs to get those dependencies, so you usually end up having to refactor loads of classes along the way to just pass a bit of config down to where the instance gets created.

So either lots of classes are needlessly altered, you bunch the config values into one big config class which is also bad... or worst still go Service Locator!

IoC allows your class to get all its depencencies without that hassle, and manages lifetimes of instances more explicitly too.
