我已经使用CustomLayout在CollectionView中完成了一个View.在iOS6中,它的效果非常好,但是iOS7会抛出这样的异常.
由于未捕获的异常’NSInternalInconsistencyException’终止应用程序,原因:
‘layout attributes for supplementary item at index path ( {length = 2,path = 0 – 0}) changed from CustomSupplementaryAttributes: 0xd1123a0 index path: (NSIndexPath: 0xd112580 {length = 2,path = 0 – 0}); element kind: (identifier); frame = (0 0; 1135.66 45); zIndex = -1; to CustomSupplementaryAttributes: 0xd583c80 index path: (NSIndexPath: 0xd583c70 {length = 2,path = 0 – 0}); element kind: (identifier); frame = (0 0; 1135.66 45); zIndex = -1; without invalidating the layout’
解决方法
您需要在更新之前使现有布局无效,请参阅错误消息的结尾:
without invalidating the layout’
[collectionViewLayout invalidateLayout];
