在Xcode 8升级后，iOS10中的应用程序崩溃，malloc错误返回 [英] App crashes in iOS10 after Xcode 8 upgrade, malloc error returned
本文介绍了在Xcode 8升级后，iOS10中的应用程序崩溃，malloc错误返回的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
我最近升级到iOS10和Xcode 8，以下这些以前的工作代码现在不再工作了。当代码运行应用程序崩溃并且在控制台中显示以下错误消息：
I have recently upgraded to iOS10 and Xcode 8, following this some previously working code is now no longer working. When the code runs the app crashes and the following error message is displayed in the console:
malloc： *对象0x1700bea80的错误：被释放的指针未分配
* 在malloc_error_break中设置一个断点来调试
malloc: * error for object 0x1700bea80: pointer being freed was not allocated * set a breakpoint in malloc_error_break to debug
我已经做了一些测试，并将错误缩小到下面的函数createNativeAd
I have done some testing and have narrowed the error to the function 'createNativeAd' in the following code.
任何人都可以看到为什么可能会抛出此错误？
Can anyone see why this error might be thrown?
