Why bother to use Memory warning event methods?

If my app uses less than 10MB do I have to bother to use those methods? I know that they are for caching low memory situations but this might occur only if you do not tested you app before releasing it. If you have tested your app, the app does not have leaks, have a small memory footprint, then why should anyone bother to use memory warning methods?

Your app is probably not the only thing running on the device. Other apps and processes are also taking up memory, and in some situations they may need it more than you. It's always a good idea to respond to memory warnings by releasing cached data that can easily be loaded again. That way the operating system has control over the memory usage, and it won't have to terminate your app.
