exception NSUnknownKeyexception

Hi i got this error , can anyone help me? Terminating app due to uncaught exception 'NSUnknownKeyException', reason: '[<PlaylistMasterViewController 0x7fe5fb5130a0> setValue:forUndefinedKey:]: this class is not key value coding-compliant for the key playListImageView0.'

And here is the MasterViewController.m

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

@interface PlaylistMasterViewController ()

@end

@implementation PlaylistMasterViewController

- (void)viewDidLoad {
    [super viewDidLoad];
    [self.singleButton setTitle:@"Press me!" forState:UIControlStateNormal];

    Playlist *playlist = [[Playlist alloc] initWithIndex:0];
    self.playlistImageView0.image = playlist.playlistIcon;
}

- (void)didReceiveMemoryWarning {
    [super didReceiveMemoryWarning];
    // Dispose of any resources that can be recreated.
}

- (void)prepareForSegue:(UIStoryboardSegue *)segue sender:(id)sender{

    if([segue.identifier isEqual:@"showPlaylistDetail"]){
        PlaylistDetailViewController *playlistDetailController = (PlaylistDetailViewController *)segue.destinationViewController;
        playlistDetailController.segueLabelText = @"Yayyy!!";
    }
