英文:
SwiftUI realm database Issue passing the fetched data to another view
问题
I'm using realm database and I had issue after fetching for the data for a list and use on tap gesture property to go to the detail view it's only show the first set of data in my realm database.
这是我使用 Realm 数据库时遇到的问题，我在获取列表数据后使用"on tap gesture"属性进入详细视图时，它只显示了 Realm 数据库中的第一组数据。
I will show some pictures to illustrate.
我将展示一些图片来进行说明。
this is how my list look like
这是我的列表的外观。
and this is detail view when clicked and it's only showing the first set of data whatever what you clicked on.
当点击详细视图时，它只显示第一组数据，无论你点击了什么。
ForEach(realmManger.patterns, id: \.id) { userPattern in
patternCell(title: userPattern.title ?? "Error??", date: userPattern.dateCreated ?? Date.now)
.onTapGesture {
editPattern = true
}.sheet(isPresented: $editPattern) {
patternEdit(userPattern: userPattern)
}
}
这是代码的一部分，因为它太长，我只展示了关键部分。
struct patternEdit: View {
@EnvironmentObject var realmManger: RealmManger
@State var showAlert = false
let userPattern: Patterns
var body: some View {
Text(userPattern.title ?? "Error")
.font(.title)
.foregroundColor(Color("lightBlue"))
.padding()
}
}
这是详细视图的代码，为什么它只显示第一组数据？

.environmentObject(realmManger)
}
}
the code is too long I tried to show what important
struct patternEdit: View {
@EnvironmentObject var realmManger:RealmManger
@State var showAlert = false
let userPattern:Patterns
var body: some View {
Text(userPattern.title ?? "Error")
.font(.title)
.foregroundColor(Color("lightBlue"))
.padding()
}
and this is the code for the detail view why is it only showing the first data ?

将 .sheet() 移出 ForEach 循环，使用 .sheet(item: ...)，就像在这个示例代码中使用 @State var selectedPattern: ... 一样。
@State var selectedPattern: Patterns? // <-- 这里
// ...
var body: some View {
// ...
ForEach(realmManager.patterns, id: \.id) { userPattern in
patternCell(title: userPattern.title ?? "Error??", date: userPattern.dateCreated ?? Date.now)
.onTapGesture {
selectedPattern = userPattern // <-- 这里
}
}
}
.sheet(item: $selectedPattern) { userPattern in // <-- 这里
patternEdit(userPattern: userPattern)
.environmentObject(realmManager)
}
// ...
}
根据你的需要调整示例代码。
英文:
Take the .sheet() out of the ForEach loop and use the .sheet(item: ...),
like in this example code using @State var selectedPattern: ...
@State var selectedPattern: Patterns? // <-- here
// ...
var body: some View {
// ...
ForEach(realmManger.patterns, id: \.id) { userPattern in
patternCell(title: userPattern.title ?? "Error??", date: userPattern.dateCreated ?? Date.now)
.onTapGesture {
selectedPattern = userPattern // <-- here
}
}
.sheet(item: $selectedPattern) { userPattern in // <-- here
patternEdit(userPattern: userPattern)
.environmentObject(realmManger)
}
// ...
}
Adjust the example code to suit your purpose.
