推荐答案

您已将方法发送到已发布的对象.您可以自己找到它.
请在XCode中为您的方案打开malloc堆栈和僵尸:

You sent a method to a released object. You can find it out by yourself.
Please turn on malloc stack and zombie for your scheme in XCode:

产品->编辑方案->诊断
选中启用僵尸对象"&"Malloc堆栈"

Product -> Edit Scheme -> Diagnostics
check 'Enable Zombie Objects' & 'Malloc Stack'

然后运行该应用程序，XCode在崩溃后应进入调试器模式.在控制台上运行以下命令:

Then run the app, XCode should enter the debugger mode after crash. Run the command below at the console:

info malloc 0x1234567

info malloc 0x1234567

然后您将在控制台中找到哪个对象导致此EXC_BAD_ACCESS.

And you'll find which object cause this EXC_BAD_ACCESS in your console.
