Hi There,
I have found a suspicious memory leak when I use Scroll View, List or anything else to list a View.
This is Scroll view with Lazy Grid define:
struct TravelingView1: View {
var body: some View {
ScrollView {
LazyVGrid(columns: [GridItem(.flexible())]) {
ForEach(0..<10) {_ in
Rectangle()
.frame(height: 20)
}
}
}
.frame(height: 200)
}
}
And Button Style in the View as:
struct ScreenView1: View {
@ObservedObject var drawRadioButtonViewModel: DrawRadioButtonViewModel1
var body: some View {
RadioButton(type: .radioButton, toggle: drawRadioButtonViewModel.isRadioCheck,
identifier: "Quick Split",
radioWidth: 302,
action: { [weak drawRadioButtonViewModel] in
drawRadioButtonViewModel?.updateToggleCheck()
},
label: {})
.offset(x: -CGFloat(100)/2, y: CGFloat(100))
Button(drawRadioButtonViewModel.isRadioCheck ? "Checked" : "Unchecked", action: { [weak drawRadioButtonViewModel] in
drawRadioButtonViewModel?.updateToggleCheck()
})
.offset(x: -CGFloat(100)/2, y: CGFloat(100) + 30)
}
}
With Button Style as:
struct RadioButton<Content: View>: View {
let type: Button_styles
let toggle: Bool
var isDisable: Bool = false
let identifier: String
var radioWidth: Int
let action: () -> Void
let label: () -> Content
enum Button_styles {
case radioButton
case checkBox
}
init(type: Button_styles, toggle: Bool, isDisable: Bool = false, identifier: String, radioWidth: Int, action: @escaping () -> Void, @ViewBuilder label: @escaping () -> Content) {
self.type = type
self.action = action
self.radioWidth = radioWidth
self.label = label
self.toggle = toggle
self.isDisable = isDisable
self.identifier = identifier
}
init(action: @escaping () -> Void, @ViewBuilder label: @escaping () -> Content) {
self.init(type: .radioButton, toggle: Bool(), isDisable: Bool(), identifier: String(), radioWidth: Int(), action: action, label: label)
}
var body: some View {
Button(action: action, label: label)
.buttonStyle(RadioButtonStyle(toggle: toggle,
isDisable: isDisable,
identifier: identifier,
radioWidth: radioWidth,
action: action))
}
}
struct RadioButtonStyle: ButtonStyle {
var toggle: Bool
var isDisable: Bool
var identifier: String
var radioWidth: Int
var action: () -> Void
func makeBody(configuration _: Configuration) -> some View {
ZStack {
if isDisable {
DisableRadioButton(identifier: identifier, radioWidth: radioWidth, action: action)
} else {
if toggle {
SelectedRadioButton(identifier: identifier, radioWidth: radioWidth, action: action)
} else {
NormalRadioButton(identifier: identifier, radioWidth: radioWidth, action: action)
}
}
}
}
}
struct SelectedRadioButton: View {
var identifier: String
var radioWidth: Int
var action: () -> Void
var body: some View {
let offsetX = radioWidth / 2 + 20/2 + 12
ZStack {
Image("common_check_on")
.frame(width: CGFloat(20), height: CGFloat(20))
Text(identifier)
.shadow(color: .black.opacity(0.75), radius: 1, x: 1, y: 1)
.font(.system(size: 15))
.frame(width: CGFloat(radioWidth), height: CGFloat(20), alignment: .leading)
.offset(x: CGFloat(offsetX), y: 0)
.foregroundColor(.black)
.onTapGesture {
action()
}
}
}
}
struct NormalRadioButton: View {
var identifier: String
var radioWidth: Int
var action: () -> Void
var body: some View {
let offsetX = radioWidth / 2 + 20/2 + 12
ZStack {
Image("common_check_off")
.frame(width: CGFloat(20), height: CGFloat(20))
Text(identifier)
.shadow(color: .black.opacity(0.75), radius: 1, x: 1, y: 1)
.font(.system(size: 15))
.frame(width: CGFloat(radioWidth), height: CGFloat(20), alignment: .leading)
.offset(x: CGFloat(offsetX), y: 0)
.foregroundColor(.black)
.onTapGesture {
action()
}
}
}
}
struct DisableRadioButton: View {
var identifier: String
var radioWidth: Int
var action: () -> Void
var body: some View {
let offsetX = radioWidth / 2 + 20/2 + 12
ZStack {
Image("common_check_off")
.frame(width: CGFloat(20), height: CGFloat(20))
Text(identifier)
.font(.system(size: 15))
.frame(width: CGFloat(radioWidth), height: CGFloat(20), alignment: .leading)
.offset(x: CGFloat(offsetX), y: 0)
.foregroundColor(.gray)
.onTapGesture {
action()
}
}
}
}
I don't have any clue to find out where cause this leak. Could you please re-check it?
