ios - UICollectionView的布局问题,为什么顶上会多出来一截?

Question

开始是好的,加了个Navigation之后就这样了.我比划了下,这段还真和Navigation的高度相当,难道是Navigation的问题?

Answer 1

Go and take a look at this property in UIViewControllerautomaticallyAdjustsScrollViewInsets.

Answer 2

This section is reserved for NavigationBar, your frame is not set properly,

Change the value (change y to 0)

or pull to the top

If this is not the problem, you need to check whether the height of the Header is set. In the Delegate, it is not set by default.

Answer 3

Can you give me some code to look at?
