iOS Red Vest project development Process Bug Summary (1)

On-line audit, re-test their app found error: "was compiled with optimization-steppingmay behave oddly; Variables May is not available "

Debugging at run time, I found that when I po parameters, always tell me that the variable is not available.

Solve:

Re-bulid Configuration to debug in the Run option, Xcode->project->scheme->edit scheme I changed it to release when I went online.

Reasons for this resolution:

The project is optimized after compiling, so the program behaves abnormally when one step, and the variables are inaccessible. This is because the compilation of the time to choose the release, and release when the time is to do a lot of optimization, resulting in the above results.
