获取“程序接收到的信号:"SIGABRT""；在iPhone SDK中 [英] Getting "Program received signal:  “SIGABRT”" in iphone sdk

问题描述

我遇到此异常:

  malloc:***对象0x754cab0的错误:双重释放***在malloc_error_break中设置断点以进行调试程序接收信号:``SIGABRT''. 

我不知道为什么仅在Iphone sdk 4.0(设备和模拟器)中生成它，却不是在Iphone sdk 3.0版本(设备和模拟器)中生成.

谁能告诉我出了什么问题以便我可以更新我的应用?

解决方案

它告诉您问题是什么:完成操作后，您可能正在释放内存，这可能是通过向对象发送太多释放消息来实现的./p>

以调试模式运行，它可能会在正确的代码行立即停止.然后，追溯您对该对象的操作.

I am getting this exception:

  malloc: *** error for object 0x754cab0: double free
 *** set a breakpoint in malloc_error_break to debug
 Program received signal:  "SIGABRT".

I don't know why it was generated only in Iphone sdk 4.0 (device and simulator), but it was not generated in Iphone sdk 3.0 versions (device and simulator).

Can anyone tell me what is going wrong so that I can update my app?

解决方案

It tells you what the problem is: You are free'ing memory when it has already been done, probably by sending too many release messages to an object.

Run in debug mode and it will probably stop right away at the correct line of code. Then, trace back what you do that object.
