我正在尝试使用SwiftUI创建一个笔记应用程序,我想显示与Apollo Reddit app类似的笔记。
它显示帖子的方式没有什么特别,它只是使用类似于带有GroupedListStyle()
的列表的界面来显示帖子,但各节之间的间距较小。
我尝试了很多技巧来减小这种间距,但是似乎都没有用。
感谢您的帮助。预先感谢!
这是我的代码:
import SwiftUI
struct NotesView: View {
let array = [
Note(title: "Mi pana miguel letra", content:
"""
[Intro: Keyan JRN & Producer Tag]
El pana Miguel, yah, ey
El pana Miguel, yah, ey (Snorkatje)
Mi pana, mi pana, yeah
Mi pana, mi pana, yeah
Mi pana, mi pana, yeah, eh-eh
Uh-uh-uh-uh-uh-uh
[Estribillo]
Ha-ha-hace un rato conocí al pana Miguel
No-no voy a mentir, se ve bastante fresco
(Ey, tío, ¿conoces a IlloJuan?) ¿Quién?
(IlloJuan) No, que quién te ha preguntado (No-oh)
Ha-hace un rato conocí al pana Miguel (Pana Miguel)
No voy a mentir, se ve bastante fresco (Bastante fresco)
Y el desgraciado de Matías que se vaya ya (Uh-uh, uh, uh)
Prefiero quedarme aquí con mi pana, sentado
"""
),
Note(title: "Note 02", content: "This is a test note."),
Note(title: "Note 03", content: "This is a test note that is supposed to be longer than just 3 lines to test the note preview. Since I cba to write...")
]
@ObservedObject var searchBar: SearchBar = SearchBar()
var body: some View {
NavigationView {
List {
if array.count > 0 {
ForEach(
array.filter
{
searchBar.text.isEmpty ||
$0.id.localizedStandardContains(searchBar.text)
},
id: \.self
) { eachNote in
Section {
NoteView(note: eachNote)
}.buttonStyle(PlainButtonStyle())
}
} else {
NavigationLink(destination: NotesTextEditor()) {
Text("Create a new post")
}
}
}
.listStyle(GroupedListStyle())
.add(self.searchBar)
}
}
}

可能的解决方案是使用自定义的a-la组分隔符,而不是标准的
。在某些复制的代码上使用Xcode 11.4 / iOS 13.4进行了测试。
List {
ForEach(array.indices, id: \.self) { i in
VStack(spacing: 0) {
Text(self.array[i].title)
.padding(.horizontal)
Text(self.array[i].content)
.padding(.horizontal)
if i != self.array.count - 1 { // don't show for last
Rectangle().fill(Color(UIColor.systemGroupedBackground))
.frame(height: 16) // << fit as you need
}
}.listRowInsets(EdgeInsets()) // << avoid extra space
}
}.listStyle(GroupedListStyle())
