在将集合视图控制器添加到情节提要并命名自定义类时，是否有人遇到 Xcode 6 问题？

-> 我将一个集合视图控制器拖到我的场景中 -> 添加一个新文件 -> 使用 UICollectionViewController 的子类将其命名为“LCCollectionViewController”。

接下来，我在 storyboard 中选择 Collection View Controller，并在身份检查器中命名自定义类 LCCollectionViewController。

问题：文档大纲仍然显示名称为 Collection View Controller。

代码以防万一：LCCollectionViewController.m

@interface LCCollectionViewController ()
{
   NSArray *theImages;
}
@end

@implementation LCCollectionViewController

    static NSString * const reuseIdentifier = @"Cell";

- (void)viewDidLoad {
   [super viewDidLoad];

   [self.collectionView registerClass:[UICollectionViewCell class] forCellWithReuseIdentifier:reuseIdentifier];

moonImages = [NSArray arrayWithObjects:@"image1.gif", @"image2.gif", @"image3.gif", @"image4.gif", nil];
}

#pragma mark <UICollectionViewDataSource>

- (NSInteger)collectionView:(UICollectionView *)collectionView numberOfItemsInSection:(NSInteger)section {

return [moonImages count];

}

- (UICollectionViewCell *)collectionView:(UICollectionView *)collectionView cellForItemAtIndexPath:(NSIndexPath *)indexPath {
UICollectionViewCell *cell = [collectionView dequeueReusableCellWithReuseIdentifier:reuseIdentifier forIndexPath:indexPath];

// Configure the cell
UIImageView *theImageView = (UIImageView *)[cell viewWithTag:100];
theImageView.image = [theImages objectAtIndex:indexPath.row];
    return cell;
}
@end

I encountered same bug in xcode6. What helped me was to change subclass to any other viewcontroller subclass you have set up already (perhaps create temporary one if none is available) and then change it back to LLCollectionViewController.
