/**
 *  if you want to get the reason that can cause crash, you can add observer notification in AppDelegate.
 *  for example: 
 *
 *  [[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(dealwithCrashMessage:) name:AvoidCrashNotification object:nil];
 *  
 *  ===========================================================================
 *  
 *  你如果想要得到导致崩溃的原因，你可以在AppDelegate中监听通知，代码如上。
 *  不管你在哪个线程导致的crash,监听通知的方法都会在主线程中
