ios – 如何识别iPad应用程序崩溃的原因？

iOS 前端之家
前端之家收集整理的这篇文章主要介绍了ios – 如何识别iPad应用程序崩溃的原因？，前端之家小编觉得挺不错的，现在分享给大家，也给大家做个参考。
我正在开发一个iPad应用程序,我正面临崩溃问题,但无法找到它背后的原因.

崩溃后它只指向main.mm文件.

尝试：

  1. - NSLogs
  2.  - NSZombiEnabled

以下是崩溃日志.据我所知,它正在使用一些已经被释放的内存位置.但是如何识别,它是哪个对象？

解决方法

看起来你好像忘记删除电影回调的观察者： 
  1. -(void) dealloc
  2. {
  3.     [[NSNotificationCenter defaultCenter] removeObserver:self];
  4. }

电影播放器​​(通过NSNotificationCenter)可能是使用某些内存位置的对象,该内存位置在尝试通知其观察者时已被释放
