问题 I would like it to operate similarly to how the normal test framework works - if you the tests from the Product->Run tests menu item, the output should appear in the left sidebar window. I found a guide for using xcode 3 with boost test, but couldn't figure out how to translate those instructions for xcode 4 (if it is even possible). Finally, I'm building an iPhone application. I could get boost running using the #include <boost/test/included/unit_test.hpp> , however it is pretty slow. Using

问题 I'm trying to embed a private framework (last paragraph) in my application bundle using XCode 4 and following Apple's (seemingly) outdated instructions. In my case, I'm Using Separate Xcode Projects For Each Target . This is the final step: In the General tab of the inspector window, add your framework as a dependency for the application. Adding this dependency causes Xcode to build the framework target before building the application target. The build dependency you establish in the

问题 In the Instruments under Allocations, for the "All Allocations" line the "Live Bytes" and "Overall Bytes" show a very small amount of memory (~2.5MB) and they seem to be very stable. But the "# Living" and "# Overall" keep going up gradually. Question: Which columns are more important in term of finding out memory footprint for my app? What are differences between "Live Bytes" vs "# Living" and "Overall Bytes" vs "# Overall"? BTW: Instruments shows no leaks memory at all. Thank you. 回答1: The
