Question

有时在应用启动时设置collectionViewLayout会导致此致命异常：

您知道为什么吗？

没有更新，因为它是在应用程序启动期间。而且我无法复制它。我从Crashlytics那里崩溃了。

Fatal Exception: NSInternalInconsistencyException Cannot set the layout [<StreamContainerLayoutIPad: 0x1056a4e60>] for [<DMZFixedCollectionView: 0x10593f600; baseClass = UICollectionView; frame = (0 0; 375 667); clipsToBounds = YES; opaque = NO; autoresize = RM+BM; gestureRecognizers = <NSArray: 0x283906640>; layer = <CALayer: 0x2837dd1a0>; contentOffset: {0, 0}; contentSize: {0, 0}; adjustedContentInset: {0, 0, 0, 0}> collection view layout: <UICollectionViewLayout: 0x10566f620>] during an update.

这是我在设置方法中的代码：

- (void)setup
{
    CollectionLayout *newLayout = [self createLayout];
    _collectionView.collectionViewLayout = newLayout;
    _layout = newLayout;
}

PS：奇怪的是，仅在iPhone上发生，而在iPad上没有发生。
