对象分配工具中的列有何含义？
我无法找到这方面的文档。没有快速信息。
这些列有这些不透明的标题：
Category
Live Bytes
# Living
# Transitory
Overall Bytes
# Overall
# Allocations (Net / Overall)
是否有文档显示这些列的含义？不用读600页？
I was unable to find the documentation for this. There is no Quick Info.
The columns have these opaque titles:
Category
Live Bytes
# Living
# Transitory
Overall Bytes
# Overall
# Allocations (Net / Overall)
Is there a document that shows what these columns mean? Without having to read 600 pages?

仪器用户指南的“使用 ObjectAlloc 仪器分析数据”部分用于提供该仪器的详细视图的一些描述（整个指南已被重写）：
对象分配按类型分组，类型显示在
Category标头下。Live Bytes列指示已分配且仍在内存中的此类对象的数量。同样，# Living列告诉您内存中仍有多少此类型的对象。Overall Bytes和#Overall列显示内存中的总大小以及该类型的所有已分配对象的数量，无论它们此时是否仍在内存中。最后，# Transitory只是# Living和#Overall之间的区别，显示在该过程中创建和销毁了多少该类型的对象。您正在分析的时间段。该表右侧的直方图是由文档中上述部分描述的，但它只是提供了上述数字的图形度量。
The "Analyzing Data with the ObjectAlloc Instrument" section of the Instruments User Guide used to provide some description of the detail view for this instrument (the whole guide has since been rewritten):
Object allocations are grouped by type, which is what appears under the
Categoryheader. TheLive Bytescolumn indicates how many of this type of object have been allocated and still are around in memory. Likewise, the# Livingcolumn tells you how many objects of this type are still around in memory. TheOverall Bytesand# Overallcolumns show the total size in memory and number of all allocated objects of that type, whether or not they are still around in memory at this time. Finally, the# Transitoryis simply the difference between# Livingand# Overall, showing how many objects of that type were created and destroyed during the time period you are analyzing.The histogram at the right of this table is described by the above-quoted section from the documentation, but it simply provides a graphical measure of the numbers described above.

这也详细说明了条形颜色的含义...
*向下滚动大约一半到分配部分。

Here's some more information on Instruments... The link in the approved answer's link reroute doesn't work.

This also breaks down what the colors of the bars mean...
*Scroll down about half way to the Allocations section.
