我有NSCollectionView由一些图片组成。当鼠标滚动到NSCollectionView时，在某些情况下应用程序崩溃。所以我启用了Zombie Object和Malloc Stack。当应用程序崩溃时，控制台中会打印-[_NSViewDrawOperation release]: message sent to deallocated instance 0x11ac815e0。我使用malloc_history打印崩溃malloc。

(gdb) info malloc-history 0x11ac815e0
warning: MallocStackLoggingNoCompact not set in target's environment so the malloc history will not be available.

但我仍然不明白这一点。任何人都可以帮助我。谢谢你！

在NSImageView的{​​{1}}中，我选择了此enter image description here

它导致draw函数在第二个线程中实现。人们遇到这个问题可能会尝试取消选择它，所以draw函数是在主线程中实现的。也许它可以帮到你。
