use of undeclared identifier 'didreceivememorywarning'

I'm getting the above message on my build a playlist Browser with Objective - C but I have no idea how to fix it.

#import "PlaylistMasterViewController.h"
#import "PlaylistDetailViewController.h"
#import "Playlist.h"

@interface PlaylistMasterViewController ()
@implementation PlaylistMasterViewController

- (void)viewDidLoad {
    [super viewDidLoad];

    for (NSUInteger index = 0; index < self.playlistImageViews.count; index++) {

        Playlist *playlist = [[Playlist alloc] initWithIndex: index];

        UIImageView *playlistImageView = self.playlistImageViews[index];

        playlistImageView.image = playlist.playlistIcon;
        playlistImageView.backgroundColor = playlist.backgroundColor;

Somewhere in your project (though I don't see it in this snippet), you tried to call the method "didreceivememorywarning" without defining it. My bet is that you were trying to define the "didReceiveMemoryWarning" method somewhere, and did something like this:

    //This line would cause a problem
    [super didreceivememorywarning];

    //You might have other code down here

This would be a version of that method that wouldn't cause a problem:

//Notice the capitalization
    //This wouldn't cause a problem
    [super didReceiveMemoryWarning];

    //You can put other code down here, too
