NSString *result;

@implementation MYSCENE
-(id) init
{
      [super init];

        id layer = [ColorLayer layerWithColor: 0x2266FFff];
        [self add:layer z:0];
        [MenuItemFont setFontSize:15];
        [MenuItemFont setFontName:@"Helvetica"];
        MenuItem *backMenu = [MenuItemFont itemFromString:@"Back" target:self selector:@selector(menuBack:)]
;
        Menu *menu = [Menu menuWithItems:backMenu,nil];

        [menu alignItemsVertically];
        [self add:menu];

    /*Text field creation*/
    myTextField = [[UITextField alloc]initWithFrame:CGRectMake(60, 165, 100, 10)];
    myTextField.placeholder=@"<Enter text>";
    [myTextField setDelegate:self];
    [window addSubview:myTextField];


    return self;
}

-(void)menuBack:(id)sender{
    NSLog(@"Back");
    TestScene *ts = [TestScene node];
    [[Director sharedDirector]replaceScene:ts];
}

-(BOOL)textFieldShouldReturn:(UITextField *)textField {
    [textField resignFirstResponder];
    return YES;
}

-(void)textFieldDidEndEditing:(UITextField *)textField{
    if(textField==myTextField){
        [myTextField endEditing:YES];

        result = myTextField.text;
        [label setString:result];
        [myTextField removeFromSuperview];
    }
}

完全にはわかりませんが、

label = [Label labelWithString:@"result" fontName:@"Helvetica" fontSize:20.0];

読むべき

label = [Label labelWithString:result fontName:@"Helvetica" fontSize:20.0];
