A way to send low memory warning to app on iPhone

I'm looking for some tool/app/tweak that can generate low memory warning on iPhone (jailbroken). Or, as alternative variant - tweak that simulates high memory usage.

I need it to test my app behavior on low memory warning.

When you are running the app on simulator, you can do it by:

Hardware (on top menu) -> Simulate Memory Warning

And for real device you can do it with a private method:

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

  • You can test this on the Simulator, thru the "Simulate Memory Warning" menu item (from the "Hardware" menu)

  • On your device, you can call the private method _performMemoryWarning

    #if DEBUG
[[UIApplication sharedApplication] performSelector:@selector(_performMemoryWarning)];
#endif

  • Another solution is to send the notification manually too:

    CFNotificationCenterPostNotification(CFNotificationCenterGetDarwinNotifyCenter(), (CFStringRef)@"UISimulatedMemoryWarningNotification", NULL, NULL, true);
