iphone - iOS Development: How can I induce low memory warnings on device?

Question

I'd like to test my app functions well in low memory conditions, but it's difficult to test. How can I induce low memory warnings that trigger the didReceiveMemoryWarning method in my views when the app is running on the device, not the simulator? Or what are some ways I can test my app under these possible conditions?

The reason I can't use the simulator is my app uses Game Center and invites don't work on the simulator.

You can call the private method:

[[UIApplication sharedApplication] performSelector:@selector(_performMemoryWarning)];

Just remember to use it on debug only, or else your app will get rejected.
