适用于iOS的移动广告SDK使用Apple的广告标识符（IDFA）。SDK根据iOS开发人员计划许可协议中规定的准则使用IDFA。您必须确保遵守用于管理此标识符的iOS开发人员计划许可协议的政策。
总而言之，似乎大多数使用AdMob的开发人员只是简单地检查了第1和第4个对勾标记并提交了他们的应用，而没有完全确定Google在其SDK中的功能，也没有任何官方信息。祝大家好运。
Google AdMob 官方并没有准确侵袭的解释，它们似乎把对侵犯用户隐私的合规风险让开发者一并承担了。
所以暂时不勾选第4个问题的答案。
I'm having the same issue here and I was a bit afraid of checking the last box, since I have no idea what the 3rd party SDK will do with the data collected and if they will respect the Limit Ad Settings.
But I found a post by a Google Admob programmer, Eric Leichtenschlag, on their forums:
The Google Mobile Ads SDK and the Google Conversion Tracking SDK utilize Apple's advertising identifier introduced in iOS 6 (IDFA). While each developer is responsible for how they access device data, the SDKs use IDFA under the guidelines laid out in the iOS developer program license agreement, including Limit Ad Tracking.
Including Limit Ad Tracking. This is what the last box is all about. So you must check the that box if you use AdMob. If you use other SDK I strongly recommend checking if they respect the guidelines as well.
Since I run only ads (Google AdMob), I checked the first (Serve ads...) and last box (I, ___, confirm...). App was approved and released, no issues.
