Intrinsic Content Size
以下を呼んだメモ
iOSのAutoLayoutにおけるIntrinsic Content Sizeについて - Qiita
ビューを表示するための最低サイズ UIViewのプロパティとしてある。 読み取り専用だがオーバーライドはできる。
StoryBoard/XIBで一時的に設定できるがこの設定は実行時には影響しない。
Content Hugging Priority コンテンツサイズよりも大きくなりにくさ Compression Resistance Priority コンテンツサイズよりも小さくなりにくさ ちなみにNSLayoutConstraintは1000なのでこれらより大きい。
UIButon 250, 750 UILabel 251,750 UIImageView 251, 750 UISwitch 750, 750 UIActivityIndicatorView 750, 750
ViewのサイズがintrinsicContentSize以上だとContent Hugging Priorityの値 ViewのサイズがintrinsicContentSize以下だとContent Compression Resistance Priorityの値

pdfをepsにする
ひとまずこんな感じでやってみた。
#!/bin/bash
# echo "$1"
# 拡張子を除く
BASE_FILE_NAME=`basename "$1" .pdf`
# echo $BASE_FILE_NAME
pdf2ps "$1"
ps2eps ${BASE_FILE_NAME}.ps
bashの参考

Stackの中のカスタムビュー
Stack内でカスタムで作ったViewが縮む問題、以下で解決できた。
NSLayoutConstraint.activate(
view.widthAnchor.constraint(equalToConstant: 320),
view.heightAnchor.constraint(equalToConstant: 320)
)

UITextViewをSwiftUIで用いる。
makeUIView, updateUIView, makeCoordinatorを実装する。Coordinatorはdelegateを処理する。
import UIKit import Combine // https://www.appcoda.com/swiftui-textview-uiviewrepresentable/ struct EditView: UIViewRepresentable { @Binding var text: String @Binding var textStyle:UIFont.TextStyle func makeUIView(context: Context) -> UITextView { let textView = UITextView() textView.font = UIFont.preferredFont(forTextStyle: textStyle) textView.autocapitalizationType = .sentences textView.isSelectable = true textView.isUserInteractionEnabled = true textView.delegate = context.coordinator return textView } func updateUIView(_ uiView: UITextView, context: Context) { uiView.text = text uiView.font = UIFont.preferredFont(forTextStyle: textStyle) } func makeCoordinator() -> Coordinator { return Coordinator($text) } } class Coordinator: NSObject, UITextViewDelegate { var text: Binding<String> init(_ text:Binding<String>) { self.text = text } func textViewDidChange(_ textView: UITextView) { self.text.wrappedValue = textView.text } func textViewDidBeginEditing(_ textView: UITextView) { } }
使う側は単に呼び出す
struct ContentView: View { @State private var message = "x" @State private var textStyle = UIFont.TextStyle.body var body: some View { VStack(alignment: .leading) { Button(action: { UIApplication.shared.endEditing() }, label: { Text("Push") }) Text(message) EditView(text: $message, textStyle: $textStyle) } } }
今回、キーボードを下げるのは
import UIKit extension UIApplication { func endEditing() { sendAction(#selector(UIResponder.resignFirstResponder), to: nil, from: nil, for: nil) } }
というextensionを用いた。
簡単な画面遷移
WebからJSON取得して表示するリスト画面と設定画面の遷移をするっでもを作ってみた。 設定画面でwebから取得するかローカルファイルから取得するか選べる。
まずモデルは
public struct Article: Codable { let title:String let url:String }
という簡単なもの。
ローカルファイルにはJSON形式で
[{"title":"[pre]【Unity】FungusをLuaで使用する方法","url":"https:\/\/qiita.com\/Humimaro\/items\/76e1730dde5c359f61ba"},...]
のようなものを準備しておく。
ファイルのロードは
import Foundation import Combine func load<T:Decodable>(_ filename:String) -> AnyPublisher<T, Error> { let data:Data guard let file = Bundle.main.url(forResource: filename, withExtension: nil) else { return Fail(error: NSError(domain: "FILE", code: 1, userInfo: nil)).eraseToAnyPublisher() } do { data = try Data(contentsOf: file) } catch { return Fail(error: NSError(domain: "FILE_DATA", code: 1, userInfo: nil)).eraseToAnyPublisher() } do { let decoder = JSONDecoder() let obj = try decoder.decode(T.self, from: data) return Just(obj).setFailureType(to: Error.self).eraseToAnyPublisher() } catch { return Fail(error: error).eraseToAnyPublisher() } }
のように、Combineを利用してみた。
Webから取得するところは
import Combine import Foundation var cancellables = [AnyCancellable]() // 記事を取得する。 func fetchArticles(isPreview:Bool) -> AnyPublisher<[Article], Error> { if isPreview { return load("articles.json") } let url = URL(string: "https://qiita.com/api/v2/items")! let request = URLRequest(url:url) return URLSession.shared .dataTaskPublisher(for: request) .tryMap({ (data, response) -> Data in guard let httpResponse = response as? HTTPURLResponse, httpResponse.statusCode == 200 else { throw URLError(URLError.Code.badServerResponse) } return data }) .decode(type: [Article].self, decoder: JSONDecoder()) .eraseToAnyPublisher() }
のように書き、引数によって、ファイルから取得できるようにしてみた。
ViewModelは
import Foundation import SwiftUI import Combine // 記事ビューモデル class ViewModel : ObservableObject { @Published private(set) var text: String = "Hello, World!" @Published private(set) var articles:[Article] = [] let previewFlg:Bool var cancels = [AnyCancellable]() init(isPreview:Bool = false) { previewFlg = isPreview } // タップした func onTapped() { // 記事を取得する fetchArticles(isPreview: previewFlg) .receive(on: DispatchQueue.main) .sink(receiveCompletion: { result in switch result { case .failure(let error): self.text = error.localizedDescription case .finished: break } }) { articles in self.articles = articles }.store(in: &cancels) } }
のように、タップしたらフェッチしてそれをarticlesに入れるという動きを書いた。
これに対応するContentViewを
import SwiftUI import Combine struct ContentView: View { @ObservedObject var viewModel:ViewModel @EnvironmentObject var settingModel:SettingModel var body: some View { VStack { Toggle(isOn:$settingModel.testMode) { Text("") } // if self.settingModel.testMode { // Text("testMode") // } Button(action: { self.viewModel.onTapped() }) { Text("更新") } List(viewModel.articles, id: \.title) { article in HStack { Text(article.title) Spacer() Button("open") { UIApplication.shared.open( URL(string: article.url)! ) } } } Text(viewModel.text) } } } struct ContentView_Previews: PreviewProvider { static var previews: some View { ContentView(viewModel: ViewModel(isPreview: true)).environmentObject(SettingModel()) } }
のようにした。リスト表示の部分が先程のarticlesの表示をする。 設定からの情報を表示するためにenvironmentObjectも使っている。
設定画面は
import SwiftUI struct SettingView: View { @EnvironmentObject var settingModel:SettingModel var body: some View { VStack { HStack { Text("TestMode") Spacer() Toggle(isOn: $settingModel.testMode) { Text(settingModel.testMode ? "":"") } }.padding() } } } struct Setting_Previews: PreviewProvider { static var previews: some View { SettingView().environmentObject(SettingModel()) } }
という単純なもの、settingModelはenvironmentObjectでSceneDelegateで注入されていて
import Foundation import Combine import SwiftUI // 設定モデル class SettingModel : ObservableObject { @Published var testMode: Bool = false }
BaseViewはこの２つをとりまとめていて、
import SwiftUI struct BaseView: View { @State var setting:Bool = false var body: some View { NavigationView { VStack { Button("設定") { self.setting = true print("x") } ContentView(viewModel: ViewModel()) NavigationLink(destination: SettingView(), isActive: $setting) { EmptyView() } } }.navigationViewStyle(StackNavigationViewStyle()) } } struct BaseView_Previews: PreviewProvider { static var previews: some View { BaseView().environmentObject(SettingModel()) } }
のようにNavigationLinkで設定画面に移動できるようにしている。
これで実装できたが、実際は設定画面の情報をContentのViewModelに渡せていなくて ローカルファイルの読み込みができていない。 そのところは変える必要があるだろう。
簡単なViewModel
ごく簡単にViewModelを作ってみた。
まずモデルは
struct Article: Codable { let title:String let url:String } func fetchArticles() -> AnyPublisher<[Article], Error> { let url = URL(string: "https://qiita.com/api/v2/items")! let request = URLRequest(url:url) return URLSession.shared .dataTaskPublisher(for: request) .map({$0.data}) .decode(type: [Article].self, decoder: JSONDecoder()) .eraseToAnyPublisher() }
ViewModelはこのようにボタンタップをしたらtextが変わる形に書いておく。 ObservableObjectを継承する。
import Foundation import SwiftUI import Combine class ViewModel : ObservableObject { @Published private(set) var text: String = "Hello, World!" var cancels = [AnyCancellable]() func onTapped() { fetchArticles() .receive(on: DispatchQueue.main) .sink(receiveCompletion: {_ in }) { articles in self.text = articles.description }.store(in: &cancels) } }
ViewでViewModelをつなげる。@ObservedObjectを使う。
import SwiftUI import Combine struct ContentView: View { @ObservedObject var viewModel = ViewModel() var body: some View { VStack { Button(action: { self.viewModel.onTapped() }) { Text("Push") } Text(viewModel.text) } } }
ここではエラーについて議論していない。
combineの簡単な例
PassthroughSubject と CurrentValueSubject
を使ってみた。おおよそRxSwift的に使えると思った。
func test() -> Void { let pub = PassthroughSubject<Int, Error>() _ = pub .sink(receiveCompletion: { _ in }) { value in print("new val -> \(value)") } pub.send(10) pub.send(100) pub.send(completion: .finished) } //test() func test2() -> Void { let pub = CurrentValueSubject<Int, Error>(100) _ = pub.sink(receiveCompletion: {_ in }, receiveValue: { (value) in print("new val -> \(value)") }) pub.send(100) pub.send(1000) pub.send(completion: .finished) } //test2() func test3() -> Void { let pub = [1,2,3,4,5,6,7,8,9,10].publisher _ = pub.sink(receiveValue: { value in print("new val -> \(value)") }) } //test3() func test4() -> Void { let pub = [1,2,3,4,5].publisher let pub2 = pub.map { (x) -> Int in return x*2 } _ = pub2.sink(receiveValue: { value in print("new val -> \(value)") }) } //test4() /* new val -> (4, 5) new val -> (4, 6) new val -> (4, 7) new val -> (4, 8) */ func test5() -> Void { let pub = [1,2,3,4].publisher let pub2 = [5,6,7,8].publisher let pub3 = pub.combineLatest(pub2) _ = pub3.sink(receiveValue: { value in print("new val -> \(value)") }) } //test5() /* new val -> (1, 5) new val -> (2, 6) new val -> (3, 7) new val -> (4, 8) */ func test6() -> Void { let pub = [1,2,3,4].publisher let pub2 = [5,6,7,8].publisher let pub3 = pub.zip(pub2) _ = pub3.sink(receiveValue: { value in print("new val -> \(value)") }) } //test6() func test7() -> Void { let sub = PassthroughSubject<Int, Error>() _ = sub.sink(receiveCompletion: { comp in print("\(comp)") }, receiveValue: { (value) in print("new val -> \(value)") }) sub.send(100) sub.send(120) sub.send(completion: .failure(NSError(domain: "Error!", code: 0, userInfo: nil))) } test7()
