我遇到了一个问题,我的列表下面出现了一个灰色的条,当我点击一个单元格进入其他视图时,会出现一个更大的灰色条。下面是列表视图的代码。
VStack{
NavigationView{
VStack{
List{
ForEach(answersArray.indices, id: \.self) { day in
NavigationLink(destination: DetailView(questions: self.answersArray[day].questions, answers: self.answersArray[day].answers, date: self.answersArray[day].dayDone.toString(dateFormat: "MM/dd/yy"))) {
HStack{
VStack{
ForEach(self.answersArray[day].questions.indices) { question in
//Text(question)
Text(self.answersArray[day].questions[question])
.lineLimit(1)
.frame(width: 250, height: 30, alignment: .leading)
// .padding(.vertical, 5)
//.padding(.bottom)
}
}
// .truncationMode(.tail)
//.frame(minWidth: 0, idealWidth: 200, maxWidth: .infinity, minHeight: 0, idealHeight: 50, maxHeight: 75, alignment: .leading)
Text(self.answersArray[day].dayDone.toString(dateFormat: "MM/dd/yy"))
.frame(minWidth: 0, idealWidth: 50, maxWidth: .infinity, minHeight: 0, idealHeight: 20, maxHeight: 20, alignment: .trailing)
}
.padding(.horizontal, 5)
}
//.frame(minWidth: 0, idealWidth: 250, maxWidth: .infinity, minHeight: 0, idealHeight: 50, maxHeight: 100, alignment: .center)
}
//.colorMultiply(Color("Background Green"))
// .listRowBackground(Color("Background Green"))
//.listRowBackground(Color("Background Green"))
Button(action: {
self.answersArray.append(DailyAnswer(questions: ["Question 1", "Question 2"], answers: ["I am happy", "I am sad"], dayDone: Date().addingTimeInterval(100000), lastWeek: false))
self.answersArray.append(DailyAnswer(questions: ["Question 1", "Question 2"], answers: ["I am happy", "I am sad"], dayDone: Date(), lastWeek: false))
self.answersArray.append(DailyAnswer(questions: ["Question 1", "Question 2"], answers: ["I am happy", "I am sad"], dayDone: Date(), lastWeek: false))
}) {
Text("Create cells")
}
}
.navigationBarTitle("Title")
//.colorMultiply(Color("Background Green"))
}
}
.accentColor(Color("My Gray"))
}
这里是独立视图的代码。
import SwiftUI
struct DetailView: View {
var questions : [String];
var answers : [String];
var date : String;
var body: some View {
//Color("Background Green")
//.edgesIgnoringSafeArea(.all)
NavigationView{
ZStack{
Color("Background Green")
.edgesIgnoringSafeArea(.all)
ScrollView{
VStack{
ForEach(questions.indices) { pair in
Text(self.questions[pair])
.font(.title)
.padding()
Text(self.answers[pair])
.padding()
.font(.body)
.frame(minWidth: 0, idealWidth: 250, maxWidth: 350, minHeight: 150, idealHeight: 200, maxHeight: .infinity, alignment: .topLeading)
.background(
RoundedRectangle(cornerRadius: 5)
.stroke(Color.black, lineWidth: 1)
)
}
}
.padding(.top)
.navigationBarTitle("\(date)", displayMode: .inline)
}
}
}
}
}
我也知道这看起来很像 这个问题但当我在该页面上实施解决方案时,它只是改变了顶部导航栏标题的颜色,而不是底部的灰色。
另外,这也是我对Tab栏和导航栏进行样式设计的地方。
init() {
UINavigationBar.appearance().backgroundColor = UIColor(named: "Background Green")
UITabBar.appearance().isTranslucent = false
UITabBar.appearance().barTintColor = UIColor.black
}
我看到堆栈中有很多导航视图。
VStack{
NavigationView{ // << here in first snapshot
VStack{
和
NavigationView{ // << here in second snapshot
ZStack{
由于没有提供完整的代码,所以可能还有其他的代码......
这里是一个 拇指法则注意:在一个视图层次链中必须只有一个根导航视图。因此,请确保将一个NavigationView作为过去期刊选项卡的选项卡项根视图(同样,仅根据提供的代码进行假设)。
