Adding a subview is as simple as,
添加子视图非常简单，
//Create subview
UIView *subview = [[UIView alloc] initWithFrame:CGRectMake(0, 0, self.collectionView.frame.size.width, 20)];
//Add
[collectionView addSubview:subview];
//Bring to front so that it does not get hidden by cells
[collectionView bringSubviewToFront:subview];
//This will shift collectionView content down by 20px at top
[collectionView setContentInset:UIEdgeInsetsMake(subview.frame.size.height, 0, 0, 0)];
The above code will add a subview at top of collectionView. Is this what you are looking for? If not please provide more details in your question.
上面的代码将在 collectionView 的顶部添加一个子视图。这是你想要的？如果不是，请在您的问题中提供更多详细信息。
