How to show dialogue box of rate app after X times? - ios

Question

i made app with swift in Xcode and i have implemented Rate App Modal in my app but the problem is this its shown when users install the app and open for very first time but i want to show it after 2 or 3 days , so users can view my app and if he likes then he can rate my app. this is my code
let reviewService = ReviewService.shared
override func viewDidAppear(_ animated: Bool) {
super.viewDidAppear(animated)
let deadline = DispatchTime.now() + .seconds(120)
DispatchQueue.main.asyncAfter(deadline: deadline) { [weak self] in
self?.reviewService.requestReview()
}
}
and this is my ReviewService.swift file
private init() {}
static let shared = ReviewService()
private let defaults = UserDefaults.standard
private let app = UIApplication.shared
private var lastRequest: Date? {
get {
return defaults.value(forKey: "ReviewService.lastRequest") as? Date
}
set {
defaults.set(newValue, forKey: "ReviewService.lastRequest")
}
}
private var oneWeekAgo: Date {
return Calendar.current.date(byAdding: .day, value: -7, to: Date())!
}
private var shouldRequestReview: Bool {
if lastRequest == nil {
return true
} else if let lastRequest = self.lastRequest, lastRequest < oneWeekAgo {
return true
}
return false
}
func requestReview(isWrittenReview: Bool = false) {
guard shouldRequestReview else { return }
if isWrittenReview {
let appStoreUrl = URL(string: "https://itunes.apple.com/app/idxxxxxxx?action=write-review")!
app.open(appStoreUrl)
} else {
if #available(iOS 10.3, *) {
SKStoreReviewController.requestReview()
} else {
// Fallback on earlier versions
}
}
lastRequest = Date()
}
}

Answer 1

When the code finds that no previous request was saved don’t show the request. Instead save that the last request happened 4 or 5 days ago. Then in a few days the first review request will be shown.
One way to do this would be in the shouldRequestReview getter. If lastRequset is nil make a new post dated request time and save that, then return false.
