Ios MFSideMenu:UIScrollView不'；不显示图像

我在我的应用程序中使用了

MFSideMenu

，其中有4个

uicrollview

，我在这4个不同的

UIViewControllers

中使用了相同的代码，只要从

SideMenuViewController

中选择它们，它们就会被添加为子视图，这就是我用来实现这一点的代码

- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath {

if (indexPath.row == 1 //or any Index) {

    UIViewController *centerController = [[UIStoryboard storyboardWithName:@"MainStoryboard" bundle:[NSBundle mainBundle]] instantiateViewControllerWithIdentifier:@"centerController"];

    UIViewController *secondController = [[UIStoryboard storyboardWithName:@"MainStoryboard" bundle:[NSBundle mainBundle]] instantiateViewControllerWithIdentifier:@"secondController"];

    [centerController.view addSubview:secondController.view];

    UINavigationController *navigationController = self.menuContainerViewController.centerViewController;
    NSArray *controllers = [NSArray arrayWithObject:centerController];
    navigationController.viewControllers = controllers;
    [self.menuContainerViewController setMenuState:MFSideMenuStateClosed];
} }

---

这里的问题是视图控制器不显示任何图像它们显示的是UIScrollView背景，尽管，当我在另一个应用程序中测试它们时，它们是分开的工作的

在搜索了几个小时后，我在任何地方都没有找到解决方案，但我自己设法修复了它

出现此问题是因为我不应该使用

addSubView

，而应该将新的视图控制器用作

UINavigationController

像这样：

- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath {

 if (indexPath.row == 1 /*or any Index*/) {

   UIViewController *centerController = [[UIStoryboard storyboardWithName:@"MainStoryboard" bundle:[NSBundle mainBundle]] instantiateViewControllerWithIdentifier:@"centerController"];
   UIViewController *secondController = [[UIStoryboard storyboardWithName:@"MainStoryboard" bundle:[NSBundle mainBundle]] instantiateViewControllerWithIdentifier:@"secondController"];

   //Now we no longer need this-->[centerController.view addSubview:secondController.view];

   UINavigationController *navigationController = self.menuContainerViewController.centerViewController;
   //Edit starts here
   NSArray *controllers = [NSArray arrayWithObject:secondController];
   //Edit ends here
   navigationController.viewControllers = controllers;
   [self.menuContainerViewController setMenuState:MFSideMenuStateClosed]; }
}
