| Classification: | Other bug | Reproducible: | Always |
Summary:
When subclassing UICollectionViewFlowLayout, and switching layout, the CGRect passed to -layoutAttributesForElementsInRect: does not represent the collectionView's contentSize or actual position.
The sample project logs both the rectangle and the collectionViewContentSize.
Steps to Reproduce:
1. Run sample project.
2. Toggle segmented control.
3. Watch logs, see the weird values being printed
Expected Results:
I expect the rect passed into -layoutAttributesForElementsInRect: can reasonably represent the collectionView in terms of frame and size.
Actual Results:
2015-05-04 19:14:27.952 FlowLayout[7792:614203] rect {{-667, -667}, {1010, 1334}}
2015-05-04 19:14:27.952 FlowLayout[7792:614203] size {343, 517}
The numbers just don't match up.
