title: How to debug iOS crash due to memory pressure
body: <p>I'm using ARC and the app crashes saying received memory warning.
  I'm testing the application directly on the device (iPhone 4 with iOS 7.0.2) and compiling with XCode 5 using iOS 6 SDK.
  I have used the apple instruments and I am having have around a 20MB LiveBytes allocated.</p>

  <p>After 4-5 min my app has 30mb of memory.</p>

  <p>After compiling and testing the app on device I see that crash after a few minutes, just after the memory warning message. Why do not happen crash using instruments?
  However I am trying to clear this problem for a month and can't get thing rite, and I really need help.
  It looks like I do not have any leaks but I cannot find where is wrong.
  Thanks in advance for any advice.</p>
