如何获取iOS的代码覆盖率数据？

Question

I'd like to see code coverage data for an iOS project.

Apparently it used to be possible using gcov but using Xcode 4.5 does not result in any gcda files.

Do you know of any tutorials or solutions on how to get such data using the latest Xcode 4.5.1?

Thank you

Answer 1

Set the following flags in your unit test target:

Generate Test Coverage Files and Instrument Program Flow

to yes .

As far as I remember there will only be coverage files if the unit test pass.
You will find the coverage files in .../Derived Data/Your App/Intermediates/Your App.build/Objects-normal/i386

Answer 2

I went to an excellent presentation on Code coverage in Xcode at our Regular London iOS Developer Group Meeting.

You can get the slides from Lanyrd .

If I recall correctly, it's actually easier with the newer Xcode.
