XCode13、iOS15和iPadOS15上的swiftUI窗体错误

Question

我在Xcode12和iOS 14上构建了一个表单，一切都像预期的那样工作。但是在切换到13和iOS 15之后，单元格的高度是不一致的，甚至当滚动到屏幕外时也会发生变化，就像它们是可重用的表格单元格一样。

例如，我有这样的代码：* EDIT:我更改了下面的代码，以包含该页面上当前的所有内容。

    Struct EvalViewMHx: View {
    var body: some View {
    VStack {
        
        Form {
            
            Label(
                title: {
                    Text("Demographics & Medical History")
                        .font(.title)
                        .foregroundColor(.white)
                        .padding()
                },
                icon: {
                    Image(systemName: "heart.text.square.fill")
                        .resizable()
                        .aspectRatio(contentMode: .fit)
                        .foregroundColor(.white)
                    
                })
                .listRowBackground(Color.blue)

            }

                            .padding()
                        
                        Spacer()
                        
                        Toggle("", isOn: $doesNotKnowInjuryDate)
                            .frame(width: 35)
                            .padding(.horizontal)
                        
                        Text("I don't know")
                            .fontWeight(!doesNotKnowInjuryDate ? .regular : .bold)
                            .padding(.leading)
                        
                    }
                    
                    if !doesNotKnowInjuryDate {
                        DatePicker("Injury Date", selection: $injuryDate, displayedComponents: [.date])
                            .foregroundColor(Color(UIColor.systemGray3))
                            .padding()
                    }
                    
                }
                .frame(minWidth: .zero, idealWidth: .infinity, maxWidth: .infinity, minHeight: 150, idealHeight: 150, maxHeight: 150, alignment: .center)
                
                VStack(alignment: .leading) {
                    
                    HStack {
                        Text("Where is your injury?")
                        
                        Spacer()
                        
                        Text("Right")
                            .fontWeight(isInjuryOnRightSide ? .regular : .bold)
                        
                        Toggle("", isOn: $isInjuryOnRightSide)
                            .toggleStyle(SwitchToggleStyle(tint: Color(UIColor.systemGray5)))
                            .frame(width: 35)
                            .padding(.horizontal)
                        
                        Text("Left")
                            .fontWeight(!isInjuryOnRightSide ? .regular : .bold)
                            .padding(.leading)
                    }
                    .zIndex(2.0)
                    
                    
                    
                    Picker(selection: $injuryLocation, label: Text(""), content: {
                        ForEach(injuryLocations, id: \.self) { location in
                            Text(location)
                        }
                    })
                    .pickerStyle(WheelPickerStyle())
                    .frame(minWidth: .zero, idealWidth: .infinity, maxWidth: .infinity, minHeight: 100, idealHeight: 100, maxHeight: 100, alignment: .center)
                    .zIndex(1.0)
                    .padding()
                    
                    
                    
                }
                .padding()
                
                VStack(alignment: .leading) {
                    Text("How did you get hurt? (Method of Injury)")
                        .padding()
                    
                    TextEditor(text: $MOI)
                        .frame(height: 150)
                        .background(Color(UIColor.systemGray5).opacity(0.75))
                        .cornerRadius(15)
                    
                }
                .frame(minWidth: .zero, idealWidth: .infinity, maxWidth: .infinity, minHeight: 200, idealHeight: 200, maxHeight: 200, alignment: .center)
                .padding()
                
                if injuryLocation != "Lower Back" && injuryLocation != "Upper Back" && injuryLocation != "Head / Neck" && injuryLocation != "Chest" {
                    
                    VStack {
                        pastInjuryHistory(injuryLocation: $injuryLocation, hasHadSameSideInjury: $hasHadSameSideInjury, hasHadOppositeSideInjury: $hasHadOppositeSideInjury, isSameSide: true)
                        
                        pastInjuryHistory(injuryLocation: $injuryLocation, hasHadSameSideInjury: $hasHadSameSideInjury, hasHadOppositeSideInjury: $hasHadOppositeSideInjury, isSameSide: false)
                        
                    }
                }
            }
        }
    }
}
    }

(在下图中，您还可以看到顶部的一些按钮，它们只是水平滚动视图中的矩形。然后将上面的代码放在选项卡视图中的下面，如下所示：)

                        TabView(selection: $activeTab) {
            
            EvalViewMHx()
                .tag(1)
            
            EvalObjectiveView()
                .tag(2)
            
            viewThree(activeTab: $activeTab)
                .tag(3)
            
            viewFour(activeTab: $activeTab)
                .tag(4)
            
        }
        .tabViewStyle(PageTabViewStyle())
        .onChange(of: activeTab, perform: { value in
            print(activeTab)
        })
        .animation(.default)

输出显示其中一个单元格的高度完全不同。

​

​

更奇怪的是，另一个部分有一个高度为0的单元格，但仍然显示文本字段位于其他单元格之上。我有一个选择器视图，它也在这些单元格中，并将pickerStyle放到

.pickerStyle(InlinePickerStyle())

将单元格扩展到比iPad屏幕更大的尺寸，而不是像以前的版本那样放在滚轮中。

这些bug是我应该耐心等待修复的，还是我可以做些什么来修复它并继续我的项目？

也在努力解决同样的问题。结果是.animation导致了这个问题，因为它从iOS 15开始就被弃用了。删除这行代码就解决了这个问题。
