Delete unused images in the ios project using scripts.
I recently learned a major trick in reading Tang Qiao's "iOS development advanced": using scripts to delete unused images in ios. (there is a small problem in the paper. Refer to the issue on github: delete unused images in ios using scripts ).
We recommend that you save the code in A. sh file and execute the
First, why should we parameterize the script?
A) To reduce the script size and number, we can reduce the number of scripts by parameterization,
Without parameterization, we may need to copy and modify many scripts to achieve the goal.
B) make the business closer to the real customer's business. Each virtual user uses different parameter values to simulate
This approach is close to the customer's actual situ
