UICollectionView增加了上边距
我想放置一个水平显示拇指的UICollectionView控件（只有一行拇指）。由于某种原因，UICollectionView将拇指向下推44像素，因此0高度实际上是44。我假设它可能会添加这个空间来考虑导航栏高度（我只是假设）。由于我的UICollectionView仅在屏幕的一部分上，我不想要这个边距。有没有办法删除它？
I want to put a UICollectionView control that shows thumbs horizontally (only a single line of thumbs). For some reason the UICollectionView push the thumbs 44 pixels down, so the "0" height is actually "44". I assume it might be adding this space to consider the navigation bar height (I just assume). Since my UICollectionView is only on part of the screen, I don't want this margin. Is there a way to remove it?
问题可能出在集合视图的内容插入中。
尝试将 self.automaticallyAdjustsScrollViewInsets = NO; 添加到视图控制器的 viewDidLoad 方法中。
The issue may be in collection view's content insets.
Try to add self.automaticallyAdjustsScrollViewInsets = NO; into view controller's viewDidLoad method.
