如何申请微信callkit灰度测试？
答:申请微信callkit灰度测试方法步骤如下。首先测试是“邀请制”，无法主动提交申请或主动获取，大多数功能在研发出来之后，不会立马应用到微信上，而是以站内信的形式邀请部分参与，被邀请的可以选择参与灰度测试，也可以直接拒绝，但一般不支持主动申请，也无法通过任何渠道获取资格和权限。
苹果是否允许开发者收集和分享联系人数据？
苹果公司不否允许开发者收集和分享联系人数据
特别是在本次的WWDC2018上，苹果再次强调了隐私政策的变化。
苹果在iOS 12中增加了对远程镜像应用的限制、禁止了加密货币挖掘行为，这些都是对数据的控制，防止被不法分子利用， 并且近日苹果又更新了隐私策略，收紧了数据共享规则，阻止开发者获取iPhone用户联系人的数据。
目前APP Store的最新指南在5.2.1条中做出了明确的表示：
https://developer.apple.com/app-store/review/guidelines/#data-collection-and-storage5.1.2 Data Use and Sharing(i) Unless otherwise permitted by law, you may not use, transmit, or share someone’s personal data without first obtaining their permission. You must provide access to information about how and where the data will be used. Data collected from apps may only be shared with third parties to improve the app or serve advertising (in compliance with the Apple Developer Program License Agreement.). Apps that share user data without user consent or otherwise complying with data privacy laws may be removed from sale and may result in your removal from the Apple Developer Program.(ii) Data collected for one purpose may not be repurposed without further consent unless otherwise explicitly permitted by law.(iii) Apps should not attempt to surreptitiously build a user profile based on collected data and may not attempt, facilitate, or encourage others to identify anonymous users or reconstruct user profiles based on data collected from Apple-provided APIs or any data that you say has been collected in an “anonymized,” “aggregated,” or otherwise non-identifiable way.(iv) Do not use information from Contacts, Photos, or other APIs that access user data to build a contact database for your own use or for sale/distribution to third parties, and don’t collect information about which other apps are installed on a user’s device for the purposes of analytics or advertising/marketing.(v) Do not contact people using information collected via a user’s Contacts or Photos, except at the explicit initiative of that user on an individualized basis; do not include a Select All option or default the selection of all contacts. You must provide the user with a clear description of how the message will appear to the recipient before sending it (e.g. What will the message say? Who will appear to be the sender?).(vi) Data gathered from the HomeKit API, HealthKit, Consumer Health Records API, MovementDisorder APIs, ClassKit or from depth and/or facial mapping tools (e.g. ARKit, Camera APIs, or Photo APIs) may not be used for marketing, advertising or use-based data mining, including by third parties. Learn more about best practices for implementing CallKit, HealthKit, ClassKit, and ARKit.(vii) Apps using Apple Pay may only share user data acquired via Apple Pay with third parties to facilitate or improve delivery of goods and services.这篇文档的大概意思就是：在没有得到用户允许的情况下，禁止一切大数据解析还有数据收集，而且如果调用了用户隐私权限，都必须要邮件通知详细的使用情况。
如果违反协议苹果将会下架应用。
