  Xcode: Xcode 9.2 Build version 9C40b
  Android Studio: Not Found

Packages: (wanted => installed)
  react: 16.2.0 => 16.2.0
  react-native: 0.52.0 => 0.52.0

Steps to Reproduce

$ react-native run-ios

Expected Behavior

iOS simulator run without showing ignored YellowBox warnings

Actual Behavior

Reproducible Demo

I have in index.js:

import React, {Component} from "react"
import {
  AppRegistry,
  StyleSheet,
  View,
  Dimensions,
  StatusBar,
  YellowBox,
} from 'react-native'
YellowBox.ignoreWarnings = ([
  'Encountered an error loading page',    // WebView uri: result.url and url failing to load - "bloomberg suneq" https://github.com/facebook/react-native/issues/7839#issuecomment-224111608
  'Deprecation warning: moment construction falls back to js Date. This is discouraged and will be removed in upcoming major release. Please refer to http://momentjs.com/guides/#/warnings/js-date/ for more info.',
  'Task orphaned for request ',
  'Remote debugger is in a background tab which may cause apps to perform slowly',
])

This is not the case with the previous form: console.ignoredYellowBox = [...] prior to this change in RN 0.52. The 2 YellowBox warnings in screenshot above got properly ignored. Now in RN 0.52, the only way I can as a workaround suppress these YellowBox warnings is by adding a catch-all disable to my index.js:

console.disableYellowBox = true

Am I missing something in my `YellowBox.ignoreWarnings = ([…]) specs so they aren’t actually ignoring?

I am running RN 0.55.2 and I followed the docs but I am still getting yellow box warnings with both a specific error to ignore and also trying console.disableYellowBox = true;. Neither case is effective at stopping any yellow box warning messages from popping up. I have wiped the app, cache, reinstalled, etc., no dice. Any thoughts on how I can resolve this? Thx!

Seems to be a error in the documentation. This works for me:

import {YellowBox} from 'react-native'
YellowBox.ignoreWarnings([
  'Encountered an error loading page',    // WebView uri: result.url and url failing to load - "bloomberg suneq" https://github.com/facebook/react-native/issues/7839#issuecomment-224111608
  'Deprecation warning: moment construction falls back to js Date. This is discouraged and will be removed in upcoming major release. Please refer to http://momentjs.com/guides/#/warnings/js-date/ for more info.',
  'Task orphaned for request ',
  'Remote debugger is in a background tab which may cause apps to perform slowly',
])
