页面返回的时候内存不会释放

+(instancetype)informationViewController {

YNPageConfigration *configration = [YNPageConfigration defaultConfig];
configration.pageStyle = YNPageStyleTop;
configration.headerViewCouldScale = YES;
configration.headerViewScaleMode = YNPageHeaderViewScaleModeTop;
configration.showTabbar = NO;
configration.showNavigation = YES;
configration.scrollMenu = YES;
configration.aligmentModeCenter = NO;
configration.lineWidthEqualFontWidth = NO;

configration.converColor = COLOR_NAV_BG;
configration.selectedItemColor = [UIColor blackColor];
configration.normalItemColor = COLOR_TEXT_6;
configration.bottomLineBgColor = COLOR_SEPARATOR;
configration.bottomLineHeight = 1;
configration.itemFont = [UIFont systemFontOfSize:16];
configration.selectedItemFont = [UIFont systemFontOfSize:16];

CCMInformationViewController *vc = [CCMInformationViewController pageViewControllerWithControllers:[self getArrayVCs]
                               titles:[self getArrayTitles]
                               config:configration];
vc.dataSource = vc;
vc.delegate = vc;
return vc;

}

这样初始化,返回的时候内存没有释放
