In-Depth Information
NOTE
Only instruments that match the current project platform are shown; in other words, only Mac-compatible instru-
ments appear for an OS X project, and only iOS compatible instruments appear for an iOS project. There are sig-
nificant differences between the instruments supported on each.
The search field
You can use the search field to add another set of filters to the information in the detail pane. Search operations
depend on the data produced by an instrument, so searches are context-dependent.
Figure 16.8 shows how you can filter the output of the allocations instrument to show only CFArray items. In
your own projects, you can use this feature to monitor your own custom objects while hiding all other activity.
It's easy to overlook the search field, but it can be a very powerful way to filter a flood of data to a trickle of pre-
cisely targeted useful statistics.
FIGURE 16.8
Use the search field to filter the output of the allocations instrument, reducing hundreds of items to just two.
