Logging only once for UICollectionViewFlowLayout cache mismatched frame

[hollylord]

小弟我用故事版上弄了一个UICollectionview，自定义flowlayout；
设定cell的size为（401，148）
当我在它的代理方法里面取出cell的时候（UICollectionViewCell *cell = [cv dequeueReusableCellWithReuseIdentifier:@"picture" forIndexPath:indexPath];）
打印发现前4个cell的size为（50，50）；后面显示的cell的size都正常。请问这是什么原因。

下面是xcode给我的提示：
Logging only once for UICollectionViewFlowLayout cache mismatched frame
UICollectionViewFlowLayout has cached frame mismatch for index path <NSIndexPath: 0xc000000000000016> {length = 2, path = 0 - 0} - cached value: {{-72.498976843927437, 14.090629367551388}, {447.84976661094447, 189.53807857184424}}; expected value: {{0, 35}, {401, 148}}
This is likely occurring because the flow layout subclass myFlowLayout is modifying attributes returned by UICollectionViewFlowLayout without copying them

求大神帮帮忙！！！！

我也是这样的问题，没有解决 但没影响 = =

自定义flowlayout需要在

- (NSArray<UICollectionViewLayoutAttributes *> *)layoutAttributesForElementsInRect:(CGRect)rect{
    NSArray * original   = [super layoutAttributesForElementsInRect:rect];
    NSArray * array = [[NSArray alloc] initWithArray:original copyItems:YES];
    return array;
}

返回所有[super layoutAttributesForElementsInRect:rect]的拷贝
