Guideline 5.1.1 - Legal - Privacy - Data Collection and Storage
We noticed that your app requires users to register with personal information to access non account-based features. Apps cannot require user registration prior to allowing access to app content and features that are not associated specifically to the user.
Please see attached screenshot for details.
Next Steps
User registration that requires the sharing of personal information must be optional or tied to account-specific functionality. Additionally, the requested information must be relevant to the features.
Request a phone call from App Review
At your request, we can arrange for an Apple Representative to call you within the next three to five business days to discuss your App Review issue.
意思是说你不能强制用户登录注册，用户注册必须是可选的，因为你APP请求的内容与用户信息无关。
