简单触感

简单触感是 Core Haptics 的一个便捷封装，使其更容易触发瞬时触感点击，类似于 UIFeedbackGenerator。

用法

import SimpleHaptics

let haptics = SimpleHapticGenerator()

try? haptics.fire(intensity: 0.5, sharpness: 1)

与 SwiftUI 集成

简单触感与 @Environment 集成良好。您可以创建一个单独的 SimpleHapticGenerator 并将其作为环境对象传递到您的根 SwiftUI 视图，然后在任何需要触感反馈的子视图中使用它。这样可以避免不必要地初始化大量 CHHapticEngine，并允许您在应用程序生命周期事件中停止和启动触感引擎。例如，在您的 SceneDelegate 中

import SimpleHaptics
import SwiftUI

class SceneDelegate: UIResponder, UIWindowSceneDelegate {

    let haptics = SimpleHapticGenerator()

    ...

    func scene(_ scene: UIScene, willConnectTo session: UISceneSession, options connectionOptions: UIScene.ConnectionOptions) {

        let contentView = ContentView()
            .environmentObject(haptics) // Pass your haptic generator into your root View.

    ...

    // Be sure to stop the haptic generator when entering the background.
    func sceneDidEnterBackground(_ scene: UIScene) {
        haptics.stop()
    }

    func sceneWillEnterForeground(_ scene: UIScene) {
        try? haptics.start()
    }

}

然后，子视图只需创建正确类型的 @EnvironmentObject 变量即可使用它

import SimpleHaptics
import SwiftUI

struct MyView: View {

    @EnvironmentObject private var haptics: SimpleHapticGenerator

    ...

}
