Question

当我尝试在ios8中的自定义视图上添加集合视图时，我正在崩溃，而相同的代码正在使用ios7。

  UINib *customNib = [UINib nibWithNibName:@"MYVIEW" bundle:nil];
  MYVIEW *recentView = [[customNib instantiateWithOwner:self options:nil] objectAtIndex:0];

 CGRect rect = recentView.frame;
 rect.origin.y = CGRectGetMaxY(collectionViewCampaign.frame)-50;
 [recentView setFrame:rect];
 [self.scrollViewRoot addSubview:recentView];
 [recentView addCollectionView];
 [recentView reloadCollection];

INSIDE MYVIEW CLASS

- (void)addCollectionView
{
  flowLayOut = [[UICollectionViewFlowLayout alloc] init];
[flowLayOut setItemSize:CGSizeMake(200, 320)];
[flowLayOut setScrollDirection:UICollectionViewScrollDirectionHorizontal];
[flowLayOut setMinimumInteritemSpacing:0];
[flowLayOut setMinimumLineSpacing:5];
[flowLayOut setHeaderReferenceSize:CGSizeMake(0.0f, 20.0f)];
[flowLayOut setFooterReferenceSize:CGSizeMake(0.0f, 20.0f)];
[flowLayOut setSectionInset:UIEdgeInsetsMake(0, 20, 0, 20)];


collectionViewCampaign = [[UICollectionView alloc] initWithFrame:CGRectMake(0, 0, self.frame.size.width, 410) collectionViewLayout:flowLayOut];
[collectionViewCampaign setDataSource:self];
[collectionViewCampaign setDelegate:self];
[collectionViewCampaign setAutoresizingMask:UIViewAutoresizingFlexibleWidth];
[collectionViewCampaign setBackgroundColor:[UIColor clearColor]];
[collectionViewCampaign setShowsHorizontalScrollIndicator:NO];
[collectionViewCampaign setShowsVerticalScrollIndicator:NO];
[self addSubview:collectionViewCampaign];
[collectionViewCampaign registerNib:[UINib nibWithNibName:@"MYCollectionCell" bundle:nil] forCellWithReuseIdentifier:kCellIdentifire];
}

我正在接受以下CRASH 如果我删除线路没有崩溃。

   [self addSubview:collectionViewCampaign];
