当您将应用程序提交到App Store时,您需要检查一些内容,以便通知Apple您正在使用标识符.有关这方面的更多细节：

以下是检索广告标识符的方法：

目标C –

@import AdSupport;

…

NSString * adId = [[[ASIdentifierManager sharedManager] advertisingIdentifier] UUIDString];

斯威夫特 –

导入AdSupport

...

let myIDFA: String?
    // Check if Advertising Tracking is Enabled
    if ASIdentifierManager.shared().isAdvertisingTrackingEnabled {
        // Set the IDFA
        myIDFA = ASIdentifierManager.shared().advertisingIdentifier.uuidString
    } else {
        myIDFA = nil
    }
