ios - 如何使用 IRate Sdk 每 30 天显示一次速率警报视图

Question

我在前 6 次尝试中显示费率警报视图，之后我需要使用 Irate SDK 每 30 天显示一次。我该如何证明请帮助我。

  **First 6 attempts :**
[iRate sharedInstance].applicationBundleID = @"Bundle id";
        [iRate sharedInstance].onlyPromptIfLatestVersion = NO;
        [iRate sharedInstance].eventsUntilPrompt = 6;
        [iRate sharedInstance].daysUntilPrompt = 0;

  **to call for 30 days :**
[iRate sharedInstance].applicationBundleID = @"Bundle id";
    [iRate sharedInstance].onlyPromptIfLatestVersion = NO;
    [iRate sharedInstance].eventsUntilPrompt = 0;
    [iRate sharedInstance].daysUntilPrompt = 30;
