ios – Xcode Instruments分配中的所有堆分配和所有匿名分配是什么？

概述我有一个申请.当我重复一些动作时,匿名分配内存不断增加很多,而堆分配增加了一点.有人能帮我吗 ？谢谢 关注所有堆分配的实时字节列,以查看应用程序使用的内存量.您无法控制应用程序的匿名VM大小. Focus on the heap allocations because your app has more control over heap allocations.

Focus on the heap allocations because your app has more control over
heap allocations. Most of the memory allocations your app makes are
heap allocations.

The VM in anonymous VM stands for virtual memory.
When your app launches,the operating system reserves a block of
virtual memory for your application. This block is usually much larger
than the amount of memory your app needs. When your app allocates
memory,the operating system allocates the memory from the block it
reserved.

Remember the second sentence in the prevIoUs paragraph. The operating
system determines the size of the virtual memory block,not your app.
That’s why you should focus on the heap allocations instead of
anonymous VM. Your app has no control over the size of the anonymous
VM.
