title: Exception Types in iOS crash logs
body: <p>I've seen a few different types of crash logs since I begin learning iOS development.  </p>
  
  <p>I know that: 
  <strong>Exception Type:  EXC_BAD_ACCESS (SIGSEGV)</strong> mean we are accessing a released object.</p>
  
  <p>but don't know about:<br>
  <strong>Exception Type:  EXC_BAD_ACCESS (SIGBUS)</strong><br>
  <strong>Exception Type:  EXC_CRASH (SIGABRT)</strong><br>
  <strong>Exception Type:  EXC_BREAKPOINT (SIGTRAP)</strong></p>
  
  <p>Do you know how many Exception Types in iOS crash logs and what do they mean?</p>
