If you want to programmatically scroll to a specific row in a list, you can use the scrollTo()
method of the ScrollViewReader
view in SwiftUI. Here’s how it works:
- Wrap your list in a
ScrollViewReader
view. This view allows you to read and manipulate the scroll position of the list.
For example, the following code creates a list of 50 rows wrapped in a ScrollViewReader
:
ScrollViewReader { scrollView in List { ForEach(1...50, id: \.self) { row in Text("Row \(row)") } } }
- Use the
scrollTo()
method of theScrollViewReader
to scroll to a specific row in the list. This method takes anid
parameter that identifies the row to scroll to, and an optionalanchor
parameter that specifies where the row should be positioned within the scroll view.
For example, the following code scrolls to the 10th row and positions it at the top of the scroll view:
scrollView.scrollTo(50, anchor: .top)
- If you want to scroll to a specific row in response to a user action (such as a button tap), you can use the
onTapGesture
modifier on the button and call thescrollTo()
method within the gesture’s closure.
For example, the following code creates a button that, when tapped, scrolls to the 10th row of the list:
Button("Scroll to Row 10") { scrollView.scrollTo(10, anchor: .top) }
