℡╲_俬逩灬. 提交于 2020-01-05 04:25:08
问题 Using a List view, is there a way to access (and therefore modify) the underlying UITableView object without reimplementing the entire List as a UIViewRepresentable ? I've tried initializing a List within my own UIViewRepresentable , but I can't seem to get SwiftUI to initialize the view when I need it to, and I just get an empty basic UIView with no subviews. This question is to help find an answer for Bottom-first scrolling in SwiftUI. Alternatively, a library or other project that

ScrollView acting weired (Xcode 11 GM seed - SwiftUI)

主宰稳场 提交于 2020-01-03 05:26:29
问题 I was trying to make a custom list. And its acting weired if we add Encapsulated VStack in scrollView and try to add new row from that VStack. But we have to encapsulate because in Xcode will give "complex view complier error". I am providing full code for better understanding. Please try to run it. New element is not added as expected and its pushing everything upward. struct RowView: View { var body: some View { VStack{ HStack{ Spacer() .foregroundColor(Color.black) Spacer() } } .background

How do I efficiently filter a long list in SwiftUI?

╄→尐↘猪︶ㄣ 提交于 2020-01-02 17:36:10
问题 I've been writing my first SwiftUI application, which manages a book collection. It has a List of around 3,000 items, which loads and scrolls pretty efficiently. If use a toggle control to filter the list to show only the books I don't have the UI freezes for twenty to thirty seconds before updating, presumably because the UI thread is busy deciding whether to show each of the 3,000 cells or not. Is there a good way to do handle updates to big lists like this in SwiftUI? var body: some View {
