少了一句代码

针对iOS9以下，手势改变后。[self collectionView:self.collectionView itemAtIndexPath:oldIndexPath willMoveToIndexPath:currentIndexPath];

@lx271896700 针对iOS9以下，我这句会自动调用你所说的方法。 //移动 会调用willMoveToIndexPath方法更新数据源 [self.collectionView moveItemAtIndexPath:oldIndexPath toIndexPath:currentIndexPath];

可是我得同时写这两句代码才行： [self.collectionView moveItemAtIndexPath:oldIndexPath toIndexPath:currentIndexPath]; [self collectionView:self.collectionView itemAtIndexPath:oldIndexPath willMoveToIndexPath:currentIndexPath];

@lx271896700 我iOS8是使用ipad真机和iPhone 5s （8.1）的模拟器，是可以的。加上一句应该没影响，少一句可能就出现你这种状况……
