PSTCollectionView布局错误

Question

我使用的是PSTCollectionView，它适用于iPhone和iPad2，但在iPad Air中，它在setCollectionViewLayout或prepareLayout中崩溃。

这是错误：

) 

这是该行的崩溃：

if (CGRectIsEmpty(self.bounds) || !_collectionViewFlags.doneFirstLayout) { 
     _layout.collectionView = nil; 
     _collectionViewData = [[PSTCollectionViewData alloc] initWithCollectionView:self layout:layout]; 
     layout.collectionView = self; // HERE CRASHES 
     _layout = layout; 

     // originally the use method 
     // _setNeedsVisibleCellsUpdate:withLayoutAttributes: 
     // here with CellsUpdate set to YES and LayoutAttributes parameter set to NO 
     // inside this method probably some flags are set and finally 
     // setNeedsDisplay is called 

     _collectionViewFlags.scheduledUpdateVisibleCells = YES; 
     _collectionViewFlags.scheduledUpdateVisibleCellLayoutAttributes = NO; 

     [self setNeedsDisplay]; 

请我需要帮助，我不明白这个问题。感谢您的提前。
