引导用户为 App 评分

showing the review alert 核心代码：

import SwiftUI
import StoreKit

enum ReviewRequest {
    // Change this to how many times you want the function to be called before showing the review alert
    static var limit = 10 
    @AppStorage("runsSinceLastRequest") static var runsSinceLastRequest = 0
    @AppStorage("version") static var version = ""

    static func showReview() {
        runsSinceLastRequest += 1
        // print("runsSinceLastRequest", runsSinceLastRequest)
        let appBuild = Bundle.main.object(forInfoDictionaryKey: "CFBundleVersion") as! String // To get the app build number
        let appVersion = Bundle.main.object(forInfoDictionaryKey: "CFBundleShortVersionString") as! String // To get the app build version
        let currentVersion = "Version \(appVersion), build \(appBuild)"

        guard currentVersion != version else { return }
        guard runsSinceLastRequest == limit else { return }

        if let scene = UIApplication.shared.connectedScenes.first(where: {$0.activationState == .foregroundActive}) as? UIWindowScene {
            SKStoreReviewController.requestReview(in: scene)
            runsSinceLastRequest = 0
            version = currentVersion
        }
    }
}

使用方法，比如在首页调用：

   override func viewWillAppear(_ animated: Bool) {
        super.viewWillAppear(animated)
       
        // 用户点击几次后，引导他去评分
        ReviewRequest.showReview()
    }
