title: NSLog: log file rotation / file limits / size limits
body: <p>Now I searched a while, but didn't found any information about how <a href="https://developer.apple.com/library/mac/documentation/Cocoa/Reference/Foundation/Miscellaneous/Foundation_Functions/#//apple_ref/c/func/NSLog" rel="nofollow">NSLog</a> works in regards to log file rotation.</p>
  
  <p>Are there any file size limits? How many files will be saved? How far back can the log go? What does iOS do if the device gets low on memory? I think it will clean these files?</p>
