*記述箇所によって、表示が変わる
 
*backgroundにpaddingを指定する(cssのmargin的な効果)
[[File:swiftui_padding2.png|300px]]
<pre>
Text(host.host)
.background(Color.green)
.padding()
</pre>
*Textにpaddingを指定することになる(cssのpadding的効果)
[[File:swiftui_padding1.png|300px]]
<pre>
Text(host.host)
.padding()
.background(Color.green)
</pre>
 
===ボタンサイズ===
----
*ボタンのサイズを内容にフィットさせたい
[[File:swiftui_button_size1.png|300px]]
<pre>
Button(action: {}) {
VStack{
:
}
.padding()
.border(Color.blue, width: 3)
}
</pre>
*.buttonStyle(PlainButtonStyle()) を指定
[[File:swiftui_button_size2.png|300px]]
<pre>
Button(action: {}) {
VStack{
:
}
.padding()
.border(Color.blue, width: 3)
}.buttonStyle(PlainButtonStyle())
</pre>
===親Viewのサイズ情報を取得する===

[[File:swiftui_grid_layout1.png|200px]]
[[File:swiftui_grid_layout2.png|400px]]
<pre>
struct HostView : View {
var host: WoL.Host
var body: some View {
GeometryReader { geo in
HStack() {
Text(host.host)
.padding()
.frame(width: geo.size.width * 0.33 , alignment: .leading)
.frame(maxHeight: .infinity)
.background(Color.red)
Text(host.ip)
.padding()
.frame(width: geo.size.width * 0.33 , alignment: .leading)
.frame(maxHeight: .infinity)
.background(Color.green)
Text(host.macaddr)
.padding()
.frame(width: geo.size.width * 0.33 , alignment: .leading)
.frame(maxHeight: .infinity)
.background(Color.yellow)
}.fixedSize(horizontal: false, vertical: true)
}.frame(height: 60)
}
}

===影をつける===
---
*shadowを設定すると、内部のコンポーネント全てに影がつく、compositingGroup を指定することで、背景だけに影をつけることができる
<pre>
:
.background()
.compositingGroup()
.shadow(radius: 10)
</pre>
===Card View===

====ObservableObject を経由して親子ViewでAlertの表示フラグを共有====
[[File:swiftui_share_object.png|300px]]
*ObservableObjectを共有して、変更をSubscribeする
<pre>
struct HostListView: View {
@ObservedObject var hosts = HostList()
@ObservedObject var param = Param()
var body: some View {
VStack {
let columns =
[GridItem(.adaptive(minimum: 250, maximum: 800))]
ScrollView {
LazyVGrid(columns: columns, spacing:10) {
ForEach(hosts.hosts, id: \.id) { host in
HostView(host:host).environmentObject(param)
}
} .padding(20)
}.alert(isPresented: $param.isSaveAlert, content: {
Alert(title: Text("Title"),message: Text("Messge"),
primaryButton: .default(Text("OK"), action: {}),
secondaryButton: .cancel(Text("Cancel"),action: {}))
})
}
}
}
struct HostView : View {
@ObservedObject var host: WoL.Host
@EnvironmentObject var param: Param
var body: some View {
VStack{
HStack {
Button(action: {
self.param.isSaveAlert = true
}) {
Image(systemName: "square.and.arrow.down")
}.help(Text("save"))
}
:
}
}
}
 
class Param : ObservableObject {
@Published var isSaveAlert: Bool = false
}
</pre>
 
====@Binding を経由して親子ViewでAlertの表示フラグを共有====
[[File:swiftui_share_object.png|300px]]
*@Binding でView間で変数を共有
*呼び出し側は@State
<pre>
struct HostListView: View {
@ObservedObject var hosts = HostList()
@State var isSaveAlert = false
 
var body: some View {
VStack {
let columns =
[GridItem(.adaptive(minimum: 250, maximum: 800))]
ScrollView {
LazyVGrid(columns: columns, spacing:10) {
ForEach(hosts.hosts, id: \.id) { host in
HostView(host:host, isSaveAlert: $isSaveAlert, alertMessage: $alertMessage)
}
} .padding(20)
}.alert(isPresented: $isSaveAlert, content: {
Alert(title: Text("Title"),message: Text(alertMessage),
primaryButton: .default(Text("OK"), action: {}),
secondaryButton: .cancel(Text("Cancel"),action: {}))
})
}
}
}
struct HostView : View {
@ObservedObject var host: WoL.Host
@Binding var isSaveAlert: Bool
var body: some View {
VStack{
HStack {
Button(action: {
self.isSaveAlert = true
}) {
Image(systemName: "square.and.arrow.down")
}.help(Text("save"))
:
}
}
}
}
</pre>
=====@Binding使用時のPreview=====
*@Stateかつ、staticで宣言
*$で変数を渡す
<pre>
struct HostView_Previews: PreviewProvider {
@State static var isAlert = true
 
static var previews: some View {
let host = WoL.Host(host: "test.local", ip: "192.168.0.1", macaddr: "aa:bb:cc:dd:ee:ff", comment: "")
HostView(host: host, isAlert: $isAlert)
}
}
</pre>
