StoryboardなしでUIViewアプリ作成を始める

ステップ1: main Storyboardを削除

ステップ2: Main Interface にある”Main”を削除

ステップ3: Info.plistのUISceneStoryboardFileとMainの記述を削除

ステップ4: SceneDelegateのfunc scene() を以下のように記述

func scene(_ scene: UIScene, willConnectTo session: UISceneSession, options connectionOptions: UIScene.ConnectionOptions) {
  guard let windowScene = (scene as? UIWindowScene) else { return }
  window = UIWindow(frame: windowScene.coordinateSpace.bounds)
  window?.windowScene = windowScene
  window?.rootViewController = ViewController()
  window?.makeKeyAndVisible()
}

ステップ5: ViewControllerにコードを記述開始

import UIKit

class ViewController: UIViewController {
  let bannerHeight: CGFloat = 100.0	
  var viewWidth: CGFloat {
    view.bounds.width
  }
	
  var viewHeight: CGFloat{
    view.bounds.height
  }
	
  var topInset: CGFloat {
    view.safeAreaInsets.top
  }
	
  var bottomInset: CGFloat {
    view.safeAreaInsets.bottom
  }
	
  var appAreaHeight: CGFloat {
    viewHeight - topInset - bottomInset - bannerHeight
  }	
	
  lazy var first: UIView = {
    let view = UIView()
    view.backgroundColor = .red
    return view
  }()
	
  lazy var second: UIView = {
    let view = UIView()
    view.backgroundColor = .blue
    return view
  }()
	
  override func viewDidLoad() {
    super.viewDidLoad()
    view.backgroundColor = .white
		
    view.addSubview(first)
    view.addSubview(second)
  }
	
  override func viewWillLayoutSubviews() {
    print("topInset: \(topInset)")
    print("bottomInset: \(bottomInset)")
    first.frame = CGRect(x: 0, y: topInset + bannerHeight, width: viewWidth, height: appAreaHeight/2)
    second.frame = CGRect(x: 0, y: topInset + bannerHeight + appAreaHeight/2, width: viewWidth, height: appAreaHeight/2)
  }
}

Gradleの基本を学んでみた

Udacityの無料コースでGradleの基本を学んでみた

手順：

  1. gitHubからrepositoryをdownloadし、Android Studioで開く
  2. terminalで cd 1.01-Exercise-RunYourFirstTask
  3. mac, linux用はgradlew windows用はgradle.bat
  4. terminalで ./gradlew を実行
  5. Could not determine java version from ‘11.0.11’などのエラーが出る場合は、gradle wrapper –gradle-version=7.5 を実行すると、./gradlewが実行出来るようになった

MidiDriverをBuildする

AndroidのMidiDriverをBuildしてみた

https://github.com/KyoSherlock/MidiDriver

// まずはterminalでbuild
$ ./gradlew

// this error occurs
// * What went wrong:
// Could not determine java version from '11.0.11'.

// then, this error occurs
//  Gradle version 2.2 is required. Current version is 7.5. If using the gradle wrapper, try editing the distributionUrl in /Users/{your_user_name}/.gradle/daemon/7.5/gradle/wrapper/gradle-wrapper.properties to gradle-2.2-all.zip

// tried editing distributionUrl in gradle/wrapper/gradle-wrapper.properties
// distributionUrl=https\://services.gradle.org/distributions/gradle-2.2-all.zip
// and click "Try Again"

// then, this shows
// This version of Android Studio requires projects to use Gradle 4.8.1 or newer. This project is using Gradle 2.2.
Change to minimum versions (plugin 3.2.0, Gradle 4.8.1) and sync project
Change to latest versions (plugin 7.1.2, Gradle 7.2) and sync project
Open build file

// I chose "Change to minimum versions and sync project"
// and it works!

その後、./gradlew buildを実行すると、下記エラーメッセージ

StackOverflowにこんな情報がありました。

https://stackoverflow.com/questions/46467561/difference-between-google-and-maven-url-https-maven-google-com

つまり、google()はGradle4.x+から登場したmaven{ url ‘https://maven.google.com’ }のショートカットで、それより古いGradleを使う場合はmavenと記載しないといけないということのようです。

// build.gradle

buildscript {
    repositories {
        jcenter()
        google()
        maven {
            url 'https://maven.google.com/'
            name 'Google'
        }
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:3.2.0'

        // NOTE: Do not place your application dependencies here; they belong
        // in the individual module build.gradle files
    }
}

allprojects {
    repositories {
        jcenter()
