【中文标题】Xcode 8升级后iOS10应用崩溃，返回malloc错误【英文标题】：App crashes in iOS10 after Xcode 8 upgrade, malloc error returned 【发布时间】：2016-09-29 10:03:16 【问题描述】：我最近升级到 ios10 和 Xcode 8，在此之后一些以前工作的代码现在不再工作。当代码运行时，应用程序崩溃并在控制台中显示以下错误消息：
malloc: * 对象 0x1700bea80 的错误：未分配被释放的指针 * 在 malloc_error_break 中设置断点进行调试
我已经进行了一些测试，并将错误范围缩小到以下代码中的函数“createNativeAd”。
谁能明白为什么会抛出这个错误？

【问题讨论】：
BOOL *stop 是什么？
我不确定，它看起来可疑吗？
只是尝试删除 * 指针符号，如 BOOL stop 和 stop = YES; 可能导致问题..
不，不是那样。 'createNativeAd' 功能有问题
在createNativeAd函数内设置多个断点并检查。你知道如何设置断点吗？

btw：应该是 Mac 的 Safari。不是 iPhone 的 Safari。 是的，它发生在 macOS 和 Xcode8 上。没有这个问题设置符号断点
