UICollectionView - order cells horizontally

由 谁说胖子不能爱 提交于 2019-12-01 04:18:45
问题 So basically my problem is that my uicollectionview's cells are ordered from top to bottom, rather than from left to right. This is what it looks like - [1][4][7] [2][5][8] [3][6][9] This is what i want - [1][2][3] [4][5][6] [7][8][9] Another problem is when i scroll horizontally instead of moving the page a full 320points. It only moves enough to fit the next cell in the view. this is what it looks like - [2][3][10] [5][6][ ] [8][9][ ] this is what i want - [10][ ][ ] [ ][ ][ ] [ ][ ][ ] I

Setting corner radius on a cell kills UICollectionView's performance

由 ∥☆過路亽．° 提交于 2019-12-01 03:24:39
I have a UICollectionView that has only a few cells (about 20). Performance for this collection works great. However, as soon as I try to round the corners of the UICollectionViewCells that are being rendered by this view, my performance takes a significant hit. In my cell's init method, this is the only line I add to cause this: [self.layer setCornerRadius:15]; Since this is in the init method and I am reusing the cells properly, I don't see why this should be causing me issue. I have tried adjusting the rasterization and opacity of the sell using multiple combinations of the following, with

问题 I have a custom UICollectionViewCell whose content is also a collection and I would like to use UICollectionView to display its content. Is this possible? How would I accomplish this? I made the custom UICollectionViewCell also inheriting from UICollectionViewDataSource and define a UICollectionView internal property but things are not working as expected. Any idea? 回答1: This is possible. Typically you would create a view controller which manages the inner collection view, and add the view of
