iOS - 在 presentViewController 之后除了 navigationBar 什么都不能点击

Question

我尝试使用 didselectItemAt 方法从 View (MainCollectionViewCell.m) 呈现 viewController(BrandViewController)。所以，

- (void)collectionView:(UICollectionView *)collectionView didSelectItemAtIndexPath:(NSIndexPath *)indexPath {
        UIViewController *currentTopVC = [self currentTopViewController];
        BrandViewController *brandVC = [[UIStoryboard storyboardWithName:@"Main" bundle:nil] instantiateViewControllerWithIdentifier:@"BrandVC"];

        [currentTopVC presentViewController:brandVC animated:true completion:nil];
}

- (UIViewController *)currentTopViewController {
    UIViewController *topVC = [[[[UIApplication sharedApplication] delegate] window] rootViewController];
    while (topVC.presentedViewController) {
        topVC = topVC.presentedViewController;
    }
    return topVC;
}

此代码正确显示 BrandViewController，但我无法单击 BrandViewController 中的任何按钮或图像(后退按钮除外)。你能给我关于这个问题的任何想法吗？

已编辑:我有两个 collectionView。一个在 MainViewController(MainCollectionView) 中，另一个在 MainCollectionViewCell 中(didSelectItemAt 方法从这里调用)。

edited2:呈现的 View 层级有两个 UITransitionView

Answer 1

尝试下面的代码:

UINavigationController *currentTopVC = (UINavigationController *)[self currentTopViewController];
BrandViewController *brandVC = [[UIStoryboard storyboardWithName:@"Main" bundle:nil] instantiateViewControllerWithIdentifier:@"BrandVC"];
[currentTopVC pushViewController:brandVC animated:YES];
