Watching memory usage in iOS

Question

Is there any way to find out how much memory is available in iOS? I know that the system will pass low memory warnings when available memory gets low. However, my App has so

Answer 1

Actually each view controller has - (void)didReceiveMemoryWarning functions.

- (void)didReceiveMemoryWarning
{
    // Releases the view if it doesn't have a superview.
    [super didReceiveMemoryWarning];

    // Release any cached data, images, etc that aren't in use.
}

As suggested by the comments, you can release unused data under the comment. On the other hand, comment out [super didReceiveMemoryWarning]; to suppress memory warnings & auto release objects.
