Is there way to customize size of uitableview?


Asked by Scarlette Cervantes on Dec 13, 2021 FAQ



For a long time, a big challenge for iOS developers was custom heights and sizes for UITableView and also UICollectionView Cells. There were ways to achieve this such as ‘ Auto Layout ’, but they were ‘hacky’ and not fully implemented.
In this manner,
There is a way – just implement tableView:willDisplayHeaderView:forSection: in your delegate. The default header view will be passed into the second parameter, and from there you can cast it to a UITableViewHeaderFooterView and then add/change subviews as you wish.
Next, In a UITableView, you can quickly reload, insert, delete, and reorder rows. All these actions come with standard animations out of the box. In a scroll view, you have to write a ton of code to get the same functionality. A table view can arrange items into sections and use indexes.
Also Know,
UITableView.automaticDimension is what enables AutoLayout to calculate the height of each cell at runtime. estimatedHeaderHeight should be set to a rough estimate of the total height of its content to display the scrolling indicator. These properties can be set in the Size Inspector when selecting the TableView in your storyboard.
Additionally,
A UITableViewSource object is responsible for managing the relationship between the relatively few UITableViewCell s and the data is to be displayed. The UITableViewSource 's NumberOfSections (UITableView) and RowsInSection (UITableView, nint) methods allow the UITableView to request only the data necessary for the cells on the screen.
