两端获取权限的区别

android 调用申请权限,系统会呈现两个还是三个系统弹窗, 直到你同意或拒绝后,选择不在提示,
iOS端,调用申请权限,系统弹窗仅会弹出一次, 该次就决定了你的权限策略, 此后再调用 申请权限API 均无系统弹窗了
区别就是:
android,会一直弹出, 直到你同意或不再提示
iOS仅弹出一次,你此次必须决定授权与否, 此次过后不再弹窗,(除非重装)

所以,针对表现形式不同,逻辑也要做不同处理 (如果要做到双端一致的话)
Android端,选择不再提示后, 帮助用户跳转系统设置,交给用户自己处理
iOS端, 申请过一次后, 下次用户再进行设置 ,就应该帮用户直接跳转系统设置

Android端

PermissionsAndroid就足够了

Android 权限管理

android端对各种权限的状态获取 / 权限申请, 由于有PermissionsAndroid的关系, 可以直接在RN端处理开发
贴一下RN端处理代码, 仅关注 !isIOS逻辑分支(即Android端)内的即可, else分支内为iOS桥接代码,后面再贴出来.
