title: xcode - Network Strength in iOS
body: <p>I know that it is not really going to help me out, but still I have some doubts related to "CTGetSignalStrength()" method of Core Telephony framework. What I know about this method is:</p>
  
  <ol>
  <li>It is an undocumented method.</li>
  <li>It belongs to a Private API.</li>
  <li>If I use this method, App store will reject my application.</li>
  <li>Also, I read that there is no public API to get the Signal Strength in iOS.</li>
  </ol>
  
  <p>My reason to pick this topic up again because all the other answers are atleast 2 years old. </p>
  
  <p>And also, I have seen some applications on App store which really tells about the cellular/Wifi Strength(Like Dr.Wifi-something). </p>
  
  <p>If its not possible to get the signal Strength, how those applications are getting it? Or there is some other way now through which we can get the network Strength. I would really appreciate if someone can enlighten me on this. Thank you.</p>
  
  <p><strong>EDIT</strong> : I have checked that question before, the one in the comment, but please see that :
   1. The answer is really old.
   2. In the comments, you can see someone asked "How OpenSignal is doing there signal strength measurement?" and there is no reply to that.
   3. Every opportunity to get signal strength is either removed in the updated iOS version, or giving null or 0 as output.</p>
  
  <p>So I am not really sure if there is no solution present for the problem or, the solution is not yet updated to that question.</p>
